ASTM F2203-13(2022)(Test Method)
Standard Test Method for Linear Measurement Using Precision Steel Rule

SIGNIFICANCE AND USE
4.1 This test method provides a means for measuring linear dimensions. Accurate measurement of dimensions can be critical to meeting specifications and characterizing process performance.  
4.2 This test method should not be applied to tolerance ranges of less than 3 mm (1/8 in.) when it is preferable that test error does not exceed 30 % of tolerance range. See Precision and Bias Section for gauge repeatability and reproducibility results.  
4.3 This test method does not address acceptability criteria. These need to be jointly determined by the user and producer of the product.
SCOPE
1.1 This test method covers the measurement of linear dimension of flexible packages and packaging materials. It is recommended for use with an allowable tolerance range of 3 mm (1/8 in.) or greater based on gauge repeatability and reproducibility presented in the Precision and Bias section.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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.  
1.3 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 Methods for Measuring the Opening Size of Geohazard Nettings

SIGNIFICANCE AND USE
5.1 Using a geohazard netting as a medium to retain rock particles necessitates compatibility between it and the adjacent rock. These test methods measure the opening size of a geohazard netting which may be used to estimate the largest size of rocks or other objects that may pass through the geohazard netting without transferring load to the wire mesh or wire net.  
5.2 These test methods may be applied to other components of the geohazard netting, such as regularly spaced reinforcement elements or secondary mesh openings.  
5.3 These test methods may also be used for quality control during the manufacturing process and quality assurance that materials supplied conform to project or material specifications.
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 These test methods are index tests to measure the opening size of a geohazard netting, or its components, or both, as it has been manufactured. They can be used for estimating the largest size of rock or other object that may pass through an individual opening in the geohazard netting without transferring load to the wire mesh or wire net and may also be used for quality control purposes. These test methods are not used to determine the maximum size rock or other object that the geohazard netting may contain through mobilization of the netting’s strength. These test methods do not apply to the measurement of the opening size of a geosynthetic, such as a turf reinforcement mat or geotextile, that may be manufactured as a composite system with the geohazard netting.  
1.2 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only and are not considered standard. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard.  
1.3 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.  
1.3.1 For purposes of comparing a measured or calculated value(s) with specified limits, the measured or calculated value(s) shall be rounded to the nearest decimal of significant digits in the specified limit.  
1.3.2 The procedures used to specify how data are collected/recorded or calculated in the standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objective; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.  
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...

Standard Specification for UAS Traffic Management (UTM) UAS Service Supplier (USS) Interoperability

SIGNIFICANCE AND USE
7.1 This specification is intended to be used by USS developers, CAAs, and others to assess USS conformance with this UTM specification.
SCOPE
1.1 This specification is intended to be a global specification providing components that may be used to satisfy requirements expected to be common to many UTM-related regulations. This specification is not intended to comprehensively address all aspects of any particular UTM-related regulation or concept of operations. Similarly, because varying terminology for the same concept is frequently used across different regulations, readers should not expect an exact terminology consistency with any particular UTM-related regulation.  
1.2 This version of the specification is focused on strategic aspects of UAS operations, including strategic conflict detection, aggregate conformance of operations to their operational intents, constraint awareness, and situational awareness in the event of nonconforming or contingent operations. The intention is that this specification will evolve to address increasingly complex strategic aspects of UAS operations and potentially certain tactical aspects of UAS operations.  
1.3 This specification addresses the performance and interoperability requirements, including associated application programming interfaces (APIs), for a set of UTM roles performed by UAS Service Suppliers (USSs) in support of UAS operations.2 Roles are groupings of one or more related UTM services. A competent authority may choose to use the roles defined in this specification in establishing the granularity of authorizations granted to a USS. The roles defined in this specification are:
(1) Strategic Coordination, comprising the Strategic Conflict Detection and Aggregate Operational Intent Conformance Monitoring services;
(2) Conformance Monitoring for Situational Awareness (CMSA);
(3) Constraint Management, comprising the Constraint Management service; and
(4) Constraint Processing, comprising the Constraint Processing service.  
1.4 Section 4, Conceptual Overview, provides a description of each of the services and roles and includes further discussion on their scope.  
1.5 A regulator may choose to require that a USS support a minimum or prescribed set of roles and services and may adopt terminology other than USS for a software system that provides something other than that minimum or prescribed set of roles and services. However, for purposes of this specification, a USS is a system that provides one or more of the UTM services defined in this specification.  
1.6 A USS is not required by this specification to perform all roles or implement all defined services, providing business case flexibility for implementers. A typical USS that supports operators in the planning and execution of UAS operations may implement the Strategic Coordination, Constraint Processing, and CMSA roles. (Note that a USS providing CMSA for a UAS operation is required to also provide Strategic Coordination for the operation.) However, other implementations more limited in scope are possible. For example, a USS may implement only the Constraint Management role and be intended for use only by authorized constraint providers; or, a USS may implement only the Constraint Processing role to provide general airspace awareness to users independent of planning UAS flights. USSs may also provide additional, value-added capabilities and still be compliant with this specification as long as the value-added capabilities do not conflict with the services defined in this specification, and the implementation of services defined in this specification conforms to the applicable requirements.  
1.7 A USS may also support other UTM roles such as Remote ID and airspace access (for example, the FAA’s LAANC), specified in other documents.  
1.8 This specification addresses aspects common to all roles and services, such as Discovery and Synchronization Services (DSS), security, aud...

Geometrical product specifications (GPS) - Transition specification (ISO 21204:2020)
SIST EN ISO 21204:2020

This document defines a number of specification operators for the specification of extended edge transition features between features. An edge transition feature is an integral feature connecting two adjacent integral features. The extended edge transition feature includes portions of the adjacent features. All these specifications apply to any line in a defined direction in the extended edge transition feature. This document also defines the specification modifiers and the drawing indications for such transition specifications.
The proportions and dimensions of the graphical symbols to be used are also specified.
The specifications defined in this document are suitable for relatively simple edge transition functions, for example ensuring assembly without interference. For more complex functions, geometrical tolerancing offers more precise tools.
This document is by intention limited to only edge transition features between two planes and between a cylinder and a plane nominally perpendicular to it.
Annex A gives the first approach for an algorithm to identify toleranced features and adjacent reference sections. This algorithm is subject to change as more experience is gathered.
This document provides a set of tools to express several transition specifications. It does not present any information on the relationship between a function or a use and a transition specification.
NOTE 1  Corners (the transition between three or more features) are not edge transition features and are consequently not covered by this document.
NOTE 2  An edge transition feature exists between two single features. A defined edge transition feature has a defined nominal shape and is not sharp (r = 0).

Geometrical product specifications (GPS) - Matrix model

ISO 14638:2014 is a fundamental ISO GPS standard. It explains the concept of Geometrical Product Specification (ISO GPS), and provides a framework to illustrate how current and future ISO GPS standards address the requirements of the ISO GPS system. The framework is intended to be of use to users of ISO GPS standards, by illustrating the extent of the scope of the different standards, and showing how they relate to each other. The framework is also used for structuring the development of standards for GPS by technical committee ISO/TC 213.

ISO/TR 14253-6:2012 expands the scope of decision rules to industrial situations where the default rule of ISO 14253-1 might not be economically optimal. (ISO 14253-1 provides a default decision rule having a very high probability that a measured value resulting in product acceptance also yields a product with the corresponding measurand conforming to specifications.) ISO/TR 14253-6:2012 does not address how to determine the cost of correct decisions (accepting conforming workpieces or rejecting nonconforming workpieces) or incorrect decisions (rejecting conforming workpieces or accepting nonconforming workpieces) as this is a business concern. However, the terminology and requirements to communicate and implement the particular decision rules desired by an organization are provided along with examples to guide the reader.

Both parts are beneficial to all technical functions in a company in the interpretation of GPS specifications [i.e. tolerances of workpiece characteristics and values of maximum permissible errors (MPEs) for metrological characteristics of measuring equipment].
ISO 14253-2:2011 introduces the Procedure for Uncertainty MAnagement (PUMA), which is a practical, iterative procedure based on the GUM for estimating uncertainty of measurement without changing the basic concepts of the GUM. It is intended to be used generally for estimating uncertainty of measurement and giving statements of uncertainty for: single measurement results; the comparison of two or more measurement results; the comparison of measurement results from one or more workpieces or pieces of measurement equipment with given specifications [i.e. maximum permissible errors (MPEs) for a metrological characteristic of a measurement instrument or measurement standard, and tolerance limits for a workpiece characteristic, etc.], for proving conformance or non-conformance with the specification.
The iterative method is based basically on an upper bound strategy, i.e. overestimation of the uncertainty at all levels, but the iterations control the amount of overestimation. Intentional overestimation and not underestimation, is necessary to prevent wrong decisions based on measurement results. The amount of overestimation is controlled by economical evaluation of the situation.
The iterative method is a tool to maximize profit and minimize cost in the metrological activities of a company. The iterative method/procedure is economically self-adjusting and is also a tool to change/reduce existing uncertainty in measurement with the aim of reducing cost in metrology (manufacture). The iterative method makes it possible to compromise between risk, effort and cost in uncertainty estimation and budgeting.
