1 Scope 1.1 General This Standard establishes minimum requirements for pressure relief devices intended for use on fuel containers that comply with CSA/ANSI HGV 2, CSA B51, Part 2, or SAE J2579. Pressure relief devices designed to comply with this Standard are intended to be used with hydrogen fuel complying with SAE J2719 or ISO 14687. Pressure relief devices may be of any design or…

Scope The scope of this standard is to specify provision of connectionless user data confidentiality, frame data integrity, and data origin authenticity by media access independent protocols and entities that operate transparently to MAC Clients. NOTE—The MAC Clients are as specified in IEEE Std 802®, IEEE Std 802.1Q™, and IEEE Std 802.1X.2 To this end, it a) Specifies the requirements to…

This document gives guidance to specifiers and users on the control of eye and face hazards including physical, mechanical, chemical, optical radiation and biological and on the selection, use and maintenance of eye and face protectors. This document applies to — occupational use, — tasks that are performed similarly to those in an occupation but not in the workplace, e.g. "do-it-…

1.1 General 1.1.1 This standard covers devices for detection, monitoring or control of water supply and distribution systems in sizes DN 8 to DN 300 (NPS-1/4 to NPS-12) for commercial and residential applications and specifies requirements for materials, performance testing, environmental limitations, installation, and markings. 1.1.2 Devices for detection, monitoring or control of plumbing…

IEC 61215-1-1:2021 is available as IEC 61215-1-1:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61215-1-1:2021 lays down requirements for the design qualification of terrestrial photovoltaic modules suitable for long-term operation in open-air climates. The useful service life of…

IEC 61215-1-1:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61215-1-1:2021 lays down requirements for the design qualification of terrestrial photovoltaic modules suitable…

IEC 61215-1-1:2021 lays down requirements for the design qualification of terrestrial photovoltaic modules suitable for long-term operation in open-air climates. The useful service life of modules so qualified will depend on their design, their environment and the conditions under which they are operated. Test results are not construed as a quantitative prediction of module lifetime. In climates…

IEC 60584-3:2021 It is necessary for thermocouple temperature measurement that the electro-motive force (abbreviated as e.m.f. hereafter) of the thermocouple circuit is precisely measured by a measuring instrument. A thermocouple is electrically connected to the instrument by a proper pair of electric cables. IEC 60584-3:2021 standardizes these cables. It specifies identification and…

This document gives direction on the interpretation and application of the results of the measurement of particle deposition rate on one or more vulnerable surfaces in a cleanroom as part of a contamination control programme. It provides some instructions on how to influence the particle deposition rate and reduce the risk of particle contamination on vulnerable surfaces. This document gives…

This document specifies how to represent (not visualize) documents (instance data, not data schemas) as graphs. It does not specify how to visualize or operate on document data, but it aims at making documents easier for people to compose and comprehend by allowing for various graph-based flexible user interfaces, possibly incorporating document-visualization practices (see Introduction). In this…
