Standard Test Method for Laboratory Oil Spill Dispersant Effectiveness Using the Baffled Flask

Standard Test Method for Laboratory Oil Spill Dispersant Effectiveness Using the Baffled Flask

SIGNIFICANCE AND USE
5.1 A standard test is necessary to establish a baseline performance parameter so that dispersants can be compared, a given dispersant can be compared for effectiveness on different oils, and at different oil weathering stages, and batches of dispersant or oils can be checked for effectiveness changes with time or other factors. This test method provides a second test at higher mixing energy in addition to the Swirling Flask (Test Method F2059).  
5.2 Dispersant effectiveness varies with oil type, sea energy, oil conditions, salinity, and many other factors. Test results from this test method form a baseline at high mixing energy, but are not to be taken as the absolute measure of performance at sea. Actual field effectiveness could be more or less than this value.  
5.3 Many dispersant tests have been developed around the world. This test has been developed in recent years and provides higher mixing energies compared to other laboratory scale tests.
SCOPE
1.1 This test method covers the procedure to determine the effectiveness of oil spill dispersants on various oils in the laboratory. This test method is not applicable to other chemical agents nor to the use of such products or dispersants in open waters.  
1.2 This test method covers the use of the Baffled Flask test apparatus and does not cover other apparatuses nor are the analytical procedures described in this report directly applicable to such procedures.  
1.3 The test results obtained using this test method are intended to provide baseline effectiveness values used to compare dispersants and oil types under conditions analogous to those used in the test.  
1.4 The test results obtained using this test method are effectiveness values that should be cited as test values derived from this standard test. Dispersant effectiveness values do not directly relate to effectiveness at sea or in other apparatuses. Actual effectiveness at sea is dependent on sea energy, oil state, temperature, salinity, actual dispersant dosage, and amount of dispersant that interacts with the oil.  
1.5 The decision to use or not use a dispersant on an oil should not be based solely on this or any other laboratory test method.  
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Use of Activity and Use Limitations, Including Institutional and Engineering Controls

SIGNIFICANCE AND USE
4.1 Activity and use limitations  are typically used in conjunction with risk-based decision-making principles in Federal, state, tribal, and local remediation programs, or where residual chemicals of concern remain following an evaluation of risk or following the implementation of a remedial action (see American Bar Association's Implementing Institutional Controls at Brownfields and Other Contaminated Sites; EPA's Institutional Controls: A Site Manager's Guide to Identifying, Evaluating and Selecting Institutional Controls at Superfund and RCRA Corrective Action Cleanups; EPA’s Enforcement Discretion Guidance Regarding Statutory Criteria for Those Who May Qualify as CERCLA Bona Fide Prospective Purchasers, Contiguous Property Owners, or Innocent Landowners (“Common Elements”); EPA’s Superfund Liability Protections for Local Government Acquisitions after the Brownfields Utilization, Investment, and Local Development Act of 2018); and EPA's Strategy to Insure Institutional Control Implementation at Superfund Sites). The principal purposes of  activity and use limitations are to:  
4.1.1 Eliminate exposure pathways for, or reduce potential exposures to, chemicals of concern identified in the conceptual site model.  
4.1.2 Provide notice to property owners, holders of interests in the property, title companies, utilities, tenants, realtors, lenders, developers, appraisers and others of the presence and location of chemicals of concern that may be present on the site;  
4.1.3 Identify the objectives and goals of each activity and use limitation, as an integral component of the corrective action plan for site remediation plan;  
4.1.4 Identify the exposure assumptions upon which each activity and use limitation is based;  
4.1.5 Identify the site uses and activities which, if they were to occur in the future, would be appropriate and consistent with maintaining a condition of “acceptable risk” or “no significant risk”;  
4.1.6 Identify the site uses and activities...
SCOPE
1.1 This guide covers information for incorporating activity and use limitations that are protective of human health and the environment into federal, state, tribal or local remediation programs using a risk-based approach to corrective action. Activity and use limitations should be considered early in the site assessment and remedial action selection process, and should be considered an integral part of remedial action selection. In the event that an appropriate activity and use limitation cannot be found, the user may need to revisit the initial remedial action selection decision.  
1.2 This guide does not mandate any one particular type of activity and use limitation but merely serves to help users identify, implement and maintain the types of activity and use limitations that may be appropriate in programs using a risk-based decision-making approach.  
1.3 This guide identifies screening and balancing criteria that should be applied in determining whether any particular activity and use limitation may be appropriate. This guide identifies the need to develop long-term monitoring and stewardship plans to ensure the long-term reliability and enforceability of activity and use limitations. This guide explains the purpose of activity and use limitations in the remedial action process and the types of activity and use limitations that are most commonly available.  
1.4 This guide describes the process for evaluating potentially applicable activity and use limitations and using and screening and balancing criteria to select one or more activity and use limitations for a specific site. The guide also describes some “best practices” from a transactional, stakeholder involvement, and long-term stewardship perspective. The guide also emphasizes the importance of considering the need for, and potential applicability of, activity and use limitations EARLY in the remedial action process. This guide can be used to effectively i...

Standard Guide for Climate Resiliency Planning and Strategy

SIGNIFICANCE AND USE
4.1 The Use of this Standard Guide—This guide addresses issues related solely to adaptation strategies and development of a plan to address extreme weather and related physical changes. This guide does not include specific guidance on risk assessment, however references are provided in Appendix X3. The matrix approach does reflect general risks for certain regions of the country, based upon the frequency of extreme weather and/or conditions such as fires, floods, storms, drought, and extreme temperatures. Adaptation strategies and planning may consist of a wide variety of actions by an individual, community, or organization to prepare for, or respond to, the impacts of extreme weather.  
4.1.1 This guide does not address causes of extreme weather.  
4.1.2 This guide addresses adjustment strategies and planning that a group of people or ecosystems make to limit negative effects of extreme weather. It also addresses taking advantage of opportunities that long term extreme weather patterns may present.  
4.2 Example Users:  
4.2.1 Small businesses or enterprises;  
4.2.2 Service industries;  
4.2.3 Federal, state or municipal facilities and regulators, including departments of health and fire departments;  
4.2.4 Financial and insurance institutions;  
4.2.5 Public works staff, including water system, stormwater system, wastewater system, solid waste, and other utilities (electrical, telephone, gas, et al) and other waste managers, including liquid and solid waste haulers, treatment, recycling, disposal and transfer;  
4.2.6 Consultants, auditors, state, municipal and private inspectors and compliance assistance personnel;  
4.2.7 Educational facilities;  
4.2.8 Property, buildings and grounds management, including landscaping;  
4.2.9 Non-regulatory government agencies, such as the military;  
4.2.10 Wildlife management entities including government, tribal and NGOs.  
4.3 This guide is a first step in crafting simplified goals for managing and communic...
SCOPE
1.1 Overview—For the purposes of this guide, ‘resiliency’ refers to efforts by entities, organizations, or individuals to prepare for or adjust to future extreme weather and related physical conditions. The primary purpose is to reduce negative economic impacts associated with extreme weather.  
1.1.1 This guide presents a generalized, systematic approach to voluntary assessment and risk management of extreme climate related events and conditions. It helps the user structure their understanding of the climate related vulnerabilities and consequences they seek to manage. It helps the user identify adaptive actions of both an institutional (legal), as well as engineering (physical) nature. Options for analysis provide a priority ranking system to address the “worst first” risks of a municipality, local area or facility, addressing practicality and cost-benefit. Users may approach this analysis having initially undertaken a risk assessment to determine what they are seeking to manage, or use the guide to help determine the likely areas of greatest need.  
1.1.2 These climate adaptations or adjustments may be either protective (that is, guarding against negative impacts of extreme weather), or opportunistic (that is, taking advantage of any beneficial effects of extreme weather).  
1.1.3 This guide addresses adaptation strategies and planning in response to various impacts that may occur to individuals, organizations, human settlements or ecosystems in a broad variety of ways. For example, extreme weather might increase or decrease rainfall, influence agricultural crop yields, affect human health, cause changes to forests and other ecosystems, or impact energy supply or infrastructure.  
1.1.4 Climate-related impacts may occur locally within a region or across a country and may affect many sectors of the economy. In order to meet these challenges, this guide provides an organized, uniform approach to prepare for the impa...

Standard Test Method for Determination of Erosion Control Products (ECP) Performance in Protecting Slopes from Sequential Rainfall-Induced Erosion Using a Tilted Bed Slope

SIGNIFICANCE AND USE
5.1 This test method utilizes large-scale testing equipment and procedures established at a variety of testing laboratories over the last 30 years.  
5.2 This method is useful in evaluating ECPs and their installation to reduce soil loss and sediment concentrations when exposed to defined rainfall conditions and improving water quality exiting the area disturbed by earthwork activity by reducing suspended solids and turbidity.  
5.3 This test method is a performance test, but can also be used for acceptance testing to determine product conformance to project specifications. For project-specific conformance, unique project-specific conditions should be considered. Caution is advised since information regarding laboratory specific precision is incomplete at this time, and differences in soil and other environmental and geotechnical conditions may affect ECP performance.  
5.4 This standard can also be used as a comparative tool for evaluating the erosion control characteristics of different ECPs and can also be used to gain agency approvals.
Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.
SCOPE
1.1 This test method is used to evaluate the ability of erosion control products (ECP) to protect slopes from rainfall-induced erosion using an adjustable tilting bed slope. The standard slopes range from 2:1 to 4:1 (H:V) having a target rainfall intensity of 3.5 in./h [90 mm/h].  
1.2 There are three main elements the ECPs must have the ability to perform: 1. Absorb the impact force of raindrops, thereby reducing soil particle loosening and detachment through “splash” mechanisms; 2. Slow runoff and encourage infiltration, thereby reducing soil particle displacement and transport through “overland flow” mechanisms; and 3. Trap soil particles beneath the ECP. When comparing data from different ECPs under consideration, it is important to keep the test conditions the same for the ECPs being evaluated, for example, the rainfall intensity rate and the slope.  
1.3 The results of this test method can be used to evaluate performance and acceptability, and can be used to compare the effectiveness of different ECPs. This method provides a comparative evaluation of an ECP to baseline bare soil conditions under controlled and documented conditions. This test method can provide information about a product that is under consideration for a specific application where no performance information currently exists.  
1.4 This test method covers the use of three different soil types, ECP installation: sprayed, rolled, or dry applied, and a runoff collection procedure. This test is typically performed indoors, but may be performed outside as long as certain requirements are met. Partially enclosed facilities are acceptable providing the environmental conditions are met.  
1.5 Units—The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. Reporting of test results in units other than inch-pound shall not be regarded as nonconformance with this standard.  
1.5.1 The gravitational system of inch-pound units is used when dealing with inch-pound units. In the system, the pound (lbf) represents a unit of force (weight), while the units for mass is slugs. The slug unit is n...

Standard Test Methods and Definitions for Mechanical Testing of Steel Products

SIGNIFICANCE AND USE
4.1 The primary use of these test methods is testing to determine the specified mechanical properties of steel, stainless steel, and related alloy products for the evaluation of conformance of such products to a material specification under the jurisdiction of ASTM Committee A01 and its subcommittees as designated by a purchaser in a purchase order or contract.  
4.1.1 These test methods may be and are used by other ASTM Committees and other standards writing bodies for the purpose of conformance testing.  
4.1.2 The material condition at the time of testing, sampling frequency, specimen location and orientation, reporting requirements, and other test parameters are contained in the pertinent material specification or in a general requirement specification for the particular product form.  
4.1.3 Some material specifications require the use of additional test methods not described herein; in such cases, the required test method is described in that material specification or by reference to another appropriate test method standard.  
4.2 These test methods are also suitable to be used for testing of steel, stainless steel and related alloy materials for other purposes, such as incoming material acceptance testing by the purchaser or evaluation of components after service exposure.  
4.2.1 As with any mechanical testing, deviations from either specification limits or expected as-manufactured properties can occur for valid reasons besides deficiency of the original as-fabricated product. These reasons include, but are not limited to: subsequent service degradation from environmental exposure (for example, temperature, corrosion); static or cyclic service stress effects, mechanically-induced damage, material inhomogeneity, anisotropic structure, natural aging of select alloys, further processing not included in the specification, sampling limitations, and measuring equipment calibration uncertainty. There is statistical variation in all aspects of mechanical testin...
SCOPE
1.1 These test methods2 cover procedures and definitions for the mechanical testing of steels, stainless steels, and related alloys. The various mechanical tests herein described are used to determine properties required in the product specifications. Variations in testing methods are to be avoided, and standard methods of testing are to be followed to obtain reproducible and comparable results. In those cases in which the testing requirements for certain products are unique or at variance with these general procedures, the product specification testing requirements shall control.

Standard Practice for Electrofusion Joining Polyethylene (PE) Pipe and Fittings for Pressure Pipe Service

SIGNIFICANCE AND USE
4.1 Using the procedures and apparatus in Sections 8 and 9 and the manufacturer's instructions, pressure-tight joints as strong as the pipe itself can be made between manufacturer-recommended combinations of pipe and fittings. See Specification F1055 for performance requirements of polyethylene electrofusion fittings.
SCOPE
1.1 This practice describes procedures for making joints suitable for pressure service with polyethylene (PE) pipe and fittings by means of electrofusion joining techniques in, but not limited to, a field environment. Other suitable electrofusion joining procedures are available from various sources including fitting manufacturers. This standard does not purport to address all possible electrofusion joining procedures, or to preclude the use of qualified procedures developed by other parties that have been proven to produce reliable electrofusion joints. (Note 1)
Note 1: Reference to the manufacturer in this practice refers to the electrofusion fitting manufacturer.  
1.2 The parameters and procedure are applicable only to joining polyethylene pipe and fittings (Note 2) which are intended for PE fuel gas pipe per Specification D2513 and PE potable water, sewer and industrial pipe manufactured per Specification F714, Specification D3035, Specification F2619, and AWWA C901 and C906.
Note 2: Commercially available materials classified with a thermoplastic pipe material designation code beginning with PE 14, PE 23, PE 24, PE 27, PE 33, PE 34, PE 36, and PE 46, and PE 47 in accordance with Specification D3350 and Terminology F412 are generally acceptable for electrofusion joining using this practice.

Standard Test Method for Determining Filtering Efficiency and Flow Rate of the Filtration Component of a Sediment Retention Device

SIGNIFICANCE AND USE
5.1 This test method is used to determine the filtering efficiency and flow rate of the filtration component of a sediment retention device, such as a silt fence, a silt barrier, or a silt curtain, for specific soil tested.  
5.2 This test method may be used for the design of the filtration component of a sediment retention device to meet requirements of regulatory agencies in filtering efficiency or flow rate for the specific soil tested.  
5.2.1 The designer can use this test method to determine the spacing between sediment retention devices.  
5.3 This test method is intended for performance evaluation, as the results will depend on the specific soil evaluated. Unless testing with the default soil is desired, it is recommended that the user or representative perform the test to pre-approve products, as sediment retention device manufacturers are not typically equipped to handle or test soil requirements.  
5.4 This test method provides a means of evaluating the filtration component of sediment retention devices with different soils under various conditions that simulate the conditions that exist in a sediment retention device installation. This test method may be used to simulate several storm events on the same sediment retention device specimen. Therefore, the number of times this test is repeated per specimen is dependent upon the user and the site conditions.
SCOPE
1.1 This test method is used to determine the filtering efficiency and the flow rate of the filtration component of a sediment retention device, such as a silt fence, silt barrier, or inlet protector.  
1.1.1 The results are shown as a percentage for filtering efficiency and cubic metres per square metre per minute (m3/m2/min) or gallons per square foot per minute (gal/ft2/min) for flow rate.  
1.1.2 The filtering efficiency indicates the percent of sediment removed from sediment-laden water.  
1.1.3 The flow rate is the average rate of passage of the sediment-laden water through the filtration component of a sediment retention device.  
1.2 This test method requires several specialized pieces of equipment, such as an integrated water sampler and an analytical balance, or a vacuum filtration system. At the client’s discretion, the test soil is either a site-specific soil or a soil that is representative of a target default gradation.  
1.3 The values stated in SI units are the standard, while the inch-pound units are provided for information. The values expressed in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Metal Injection Molded Cobalt-28Chromium-6Molybdenum Components for Surgical Implant Applications

ABSTRACT
This specification covers chemical, mechanical, and metallurgical general requirements for metal injection molded (MIM) cobalt-28chromium-6molybddenum components to be used in manufacturing surgical implants. In this specification, the MIM components covered may have been densified beyond their as-sintered density by post-sinter processing. For the chemical requirements, the components supplied in this specification must conform in accordance to the chemical requirements specified herein in Table 1. The product analysis tolerances must also conform to the product tolerances presented in Table 2. The specification also enumerates the mechanical requirements for MIM components wherein the tensile properties of the MIM must conform to the mechanical properties in Table 3. The microstructural requirements and specimen preparation shall be in accordance with Guide E3 and Practice E407.
SCOPE
1.1 This specification covers chemical, mechanical, and metallurgical requirements for metal injection molded (MIM) cobalt-28chromium-6molybdenum components to be used in the manufacture of surgical implants  
1.2 The MIM components covered by this specification may have been densified beyond their as-sintered density by post-sinter processing.  
1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.

ASTM A480/A480M-23a(Specification)
Standard Specification for General Requirements for Flat-Rolled Stainless and Heat-Resisting Steel Plate, Sheet, and Strip

ABSTRACT
This specification covers general requirements for flat-rolled stainless and heat-resisting steel plate, sheet, and strip. The steel shall be made by one of the following processes: electric-arc, electric-induction, or other suitable processes. Heat and product analyses shall conform to the chemical requirements for each of the specific elements. The material shall undergo mechanical tests such as tension test, hardness test, and bend test. Special tests like intergranular corrosion test, permeability test, Charpy impact testing and tests for detrimental intermetallic phases in wrought duplex stainless steels shall be also be performed when required.
SCOPE
1.1 This specification2 covers a group of general requirements that, unless otherwise specified in the purchase order or in an individual specification, shall apply to rolled steel plate, sheet, and strip, under each of the following specifications issued by ASTM: Specifications A240/A240M, A263, A264, A265, A666, A693, A793, and A895.  
1.2 In the case of conflict between a requirement of a product specification and a requirement of this specification, the product specification shall prevail. In the case of conflict between a requirement of the product specification or a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail. The purchase order requirements shall not take precedence if they, in any way, violate the requirements of the product specification or this specification; for example, by waiving a test requirement or by making a test requirement less stringent.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The SI units are shown in brackets, except that when A480M is specified, Annex A3 shall apply for the dimensional tolerances and not the bracketed SI values in Annex A2. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.4 This specification and the applicable material specifications are expressed in both inch-pound and SI units. However, unless the order specifies the applicable “M” specification designation [SI units], the material shall be furnished in inch-pound units.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
