Standard Practice for Training Exoskeleton Users

Standard Practice for Training Exoskeleton Users

SIGNIFICANCE AND USE
4.1 This practice establishes the minimum training criteria for exoskeleton users.  
4.2 This practice does not supersede any established laws or regulations of international, national, federal, state, tribal, local, or regional governments.  
4.3 A commonly used training practice is for a competent, qualified, or certified trainer to provide to the student with written, visual, and verbal training materials that elementally breakdown the intended subject matter into a series of achievable modules. The trainer describes and demonstrates each module, and then interactively has the exoskeleton student user repeat and demonstrate specified knowledge, skills, and abilities to verify and validate the complete transfer of that knowledge, skills, and abilities.  
4.4 This practice by itself is not a training document. It is an outline of the topics required for training or evaluating exoskeleton users for competence, proficiency, certification, or license.  
4.5 The knowledge, skills, and abilities presented in the following sections are not in any particular order and do not represent a training sequence.
SCOPE
1.1 This practice establishes the minimum training requirements, including general knowledge, skills, and abilities, for personnel who use an exoskeleton as part of their duties.  
1.2 This practice applies only to exoskeletons and exosuits.  
Note 1: For more advanced exoskeletons, those that are powered, or with IT data connections/links for data transfer, or combinations thereof, upload/download requirements, ensure exoskeleton user and system operators training includes addressing all precautions so they can quickly identify and resolve any data transfer problems experienced with a fully operational exoskeleton.  
1.3 It is recognized that organizations and job responsibilities vary widely among military, medical, industrial, and emergency response communities. It is the responsibility of the user of this practice to identify the appropriate subject matter for its program and its specific needs.  
1.4 Users of this practice should consult with the exoskeleton manufacturer to ensure they have the latest and most relevant information on the exoskeleton. In addition, all training should comply with laws and regulations regarding user safety and health as well as the safety of individuals in close proximity to the user.  
1.5 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 non-conformance with the standard.  
1.6 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.  
1.7 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 Terminology for Exoskeletons and Exosuits

SCOPE
1.1 This terminology covers terms associated with exoskeletons and exosuits. By providing a common and consistent lexicon, the purpose of this terminology is to facilitate communication between individuals who may be involved in the research, design, deployment, and use of exoskeletons and exosuits in applications, including but not limited to industrial, military, emergency response, recreational, and medical areas.  
1.2 For the terminology to be harmonious with the practices in the fields, definitions have been drawn from other standards, the literature, or other public sources when possible. When no definition is available, is similar but requires change for use within standards produced by Committee F48, or in dispute, a consensus-based approach will be used to resolve definitions and add them to the lexicon. The development of this terminology is taking place in close coordination with corresponding efforts in all Committee F48 subcommittees to ensure comprehensive and consistent coverage.  
1.3 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.  
1.4 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 Test Method for Exoskeleton Use: Gait

SIGNIFICANCE AND USE
5.1 Exoskeletons are being used in the industrial/occupational, military, response, medical, and recreational sectors to enhance safety and effectiveness of the user to perform tasks. Gait is a component of many tasks that someone would do with an exoskeleton. For example, an exoskeleton may be used to help rehabilitate a patient who suffered a traumatic leg injury. In manufacturing, warehousing, military, and other similar environments, workers and soldiers in exoskeletons walk with and without carrying loads, many times over long distances, indoors or outdoors, as part of their daily activities. Fig. 1 shows examples of exoskeleton users walking, which, depending upon the task, may require people to traverse various ground surfaces while wearing an exoskeleton. The testing results of exoskeletons shall describe, in a statistically significant way, how reliably the exoskeleton is able to support tasks within the specified types of environments, confinements, and terrains, and thus provide sufficiently high levels of confidence to determine the applicability of the exoskeleton to a given task.
FIG. 1 Examples of Exoskeleton Users Walking in Various Sectors
Note 1: Examples include: (a) medical rehabilitation (courtesy Gogoa), (b) military material handling (courtesy Mawashi), (c) military soldiering (courtesy Mawashi), (d) recreational hiking through snow and (e) walking on pavement as part of daily work duties (courtesy Humotech), and (f) industrial worker standing up from a chair prior to walking (courtesy SuitX).  
5.2 This test method addresses exoskeleton safety and performance requirements expressed by manufacturing, emergency responders, military, or other organizations requesting this test. The safety and performance data captured within this test method are indicative of the test exoskeleton’s and the exoskeleton user’s capabilities.

SCOPE
1.1 Purpose:  
1.1.1 The purpose of this test method, as a part of a suite of exoskeleton use test methods, is to quantitatively evaluate an exoskeleton’s (see Terminology F3323) safety (see 1.4) or performance, or both, for gait.  
1.1.2 Exoskeletons shall possess a certain set of allowable exoskeleton user movement capabilities, including user-motion adaptability, to suit operations such as: industrial/occupational, military, response, medical or recreational. Environments in these typical sectors often pose constraints to exoskeleton user movement to various degrees. Being able to walk, as intended by the user or test requestor, while using an exoskeleton is essential for exoskeleton deployment for a variety of tasks. This test method specifies test setup, procedure, and recording to standardize this gait task for testing exoskeleton user movement.  
1.1.3 Exoskeletons shall be able to handle many types of task and terrain complexities. The required movement capabilities include, for example: walking, running, crawling, climbing, traversing gaps, hurdles, stairs, slopes, various types of floor surfaces or terrains, and confined spaces. Standard test methods are required to evaluate whether or not exoskeletons meet these requirements.  
1.1.4 ASTM Subcommittee F48.03 develops and maintains international standards for task performance and environmental considerations that include but are not limited to, standards for safety, quality, and efficiency. This subcommittee aims to develop standards for any exoskeleton application, as exemplified as in 1.1.2. The F48.03 test suite consists of a set of test methods for evaluating exoskeleton capability requirements. This gait test method is a part of the test suite. The setup, procedure, and apparatuses associated with the test methods challenge specific exoskeleton capabilities in repeatable ways to facilitate comparison of different exoskeleton models or exoskeleton capa...

Standard Practice for Documenting Environmental Conditions for Utilization with Exoskeleton Test Methods

SIGNIFICANCE AND USE
4.1 This section provides a description of the environmental conditions listed in Section 1 and describes the sub-conditions within each condition. Examples provided for many of the conditions and sub-conditions are provided as guidance only. Each of the conditions described should be evaluated and documented as set forth in Sections 5 – 7.  
4.2 Environment Consistency: Static, Dynamic, Transitional  
4.2.1 Static is when the environment is similar throughout the test apparatus. For example, there are minor fluctuations in temperature throughout the apparatus as shown in Fig. 1 and Fig. 2. Dynamic is when the environment significantly differs within the test apparatus. For example, when the temperature changes between repetitions as shown in Fig. 3. Transitional is when the environment significantly differs in different areas within the test apparatus as shown in Fig. 4. The intent here is to not give specific guidance, but to provide a high-level classification of a particular set of environmental conditions. If environment consistency is dynamic or transitional, or both, a report form (see Section 7) for each unique set of environmental conditions should be completed.
FIG. 1 Example of Static Environment Using Temperature
FIG. 2 Example of Static Environment Using Temperature and Showing a Transition Between Two Static Environments
FIG. 3 Example of Dynamic Environment Using Temperature and Showing that the Environment Changed During the Test
FIG. 4 Example of Transitional Environment Using Temperature Portions of the Environment may Remain Static or may be Dynamic (For example, Cold to Colder)  
4.3 Floor or Ground Surface:  
4.3.1 Exoskeleton mobility is affected by ground surface conditions including: surface texture/roughness, deformability, slope or lack of flatness (that is, undulation). Ground surface conditions can affect the exoskeleton: traction, vibration affecting the electronics integrity, positioning, and stability.  
4.3.2 Type(s):  ...
SCOPE
1.1 When conducting test methods, it is important to consider the role that the environmental conditions play in measurement of exoskeleton safety and performance. Exoskeletons are designed to be operated both indoors and outdoors under conditions specified by the manufacturer. Likewise, end users of the exoskeletons will be using these exoskeletons in a variety of environmental conditions. When conducting and replicating ASTM Committee F48 test methods by exoskeleton manufacturers and users, it is important to specify and document the environmental conditions under which the exoskeleton is to be tested as there will be variations in system performance caused by the conditions, especially when comparing and replicating sets of test results. It is also important to consider changes in environmental conditions during the course of operations (for example, transitions between conditions). As such, environmental conditions specified in this document are static, dynamic, or transitional, or combinations thereof; with the exoskeleton stationary or in motion. This document provides brief introduction to the following list of environmental conditions that can affect performance of the exoskeleton:  
1.1.1 Floor or ground surface;  
1.1.2 Temperature;  
1.1.3 Humidity;  
1.1.4 Atmospheric pressure;  
1.1.5 Lighting;  
1.1.6 Air flow and quality;  
1.1.7 External sensor emission;  
1.1.8 Electrical interference;  
1.1.9 Boundaries;  
1.1.10 Additional categories, for example underwater, extraterrestrial, may also be added to this standard as the exoskeleton industry applications evolve in these areas.  
1.1.11 This document then breaks down each condition into sub-categories so that the user can document the various aspects associated with the category prior to exoskeleton tests defined in ASTM Committee F48 test methods listed in Section 2. It is recommended that salient environment conditions be documented when conduc...

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. Consult with the pipe or fitting manufacturer for specific compatibility information.  
1.3 Parts that are within the dimensional tolerances given in present ASTM specifications are required to produce sound joints between polyethylene pipe and fittings when using the joining techniques described in this practice.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 The text of this practice references notes, footnotes, and appendices which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the practice.  
1.6 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.  
1.7 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.

ASTM D5141-23(Test Method)
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.
