1 Scope 1.1 This Standard provides the minimum requirements, unless otherwise specified by the authority having jurisdiction, for the purity of compressed breathing air supplied to the service outlet and for breathing air systems required to produce, store, and distribute such air. 1.2 This Standard is limited to compressed breathing air and compressed breathing air systems used in the…

1.1 This Standard establishes the test method, criteria, and device to evaluate a hydrogen fueling station dispensing system (hereinafter referred to as a “dispenser”) as it relates to achieving the protocols specified in SAE J2601 and SAE J2799 with light duty vehicle hydrogen storage systems less than 248.6 L (10 kg H70). The testing evaluation applies to dispensers designed to fill vehicle…

1 Scope 1.1 This Standard applies to photovoltaic (re)combiners rated up to 2000 V dc or 750 V ac, for use on photovoltaic (PV) systems installed in nonhazardous locations in accordance with CSA C22.1, Canadian Electrical Code, Part I. 1.2 (Re)combiners for use in photovoltaic systems that are ungrounded, positive grounded, and/or negative grounded are within the scope of this Standard…

1 Scope This part of IEC 61000 defines the immunity test methods and range of preferred test levels for electrical and electronic equipment connected to low-voltage power supply networks for voltage dips, short interruptions, and voltage variations. This standard applies to electrical and electronic equipment having a rated input current not exceeding 16 A per phase, for connection to 50 Hz…

1 Scope This part of IEC 61000 relates to the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, to ring waves occurring in low-voltage power, control and signal lines supplied by public and non-public networks. The object of this document is to establish a common reference for evaluating the immunity of electrical and electronic…

IEC 60749-20-1:2019 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 60749-20-1:2019 applies to all devices subjected to bulk solder reflow processes during PCB assembly, including…

This document specifies the validation protocol of analytical methods used for ensuring the quality of the gaseous hydrogen (H2) at hydrogen distribution bases and hydrogen fuelling stations for road vehicles using proton exchange membrane (PEM) fuel cells. It also gives recommendations on the calculation of an uncertainty budget for the amount fraction. This document is established mainly for…

This document defines the Rabin-Montgomery (RAMON) crypto suite for the ISO/IEC 18000 series of air interfaces standards for radio frequency identification (RFID) devices. Its purpose is to provide a common crypto suite for security for RFID devices that can be referred to by ISO/IEC for air interface standards and application standards. This document specifies a crypto suite for Rabin-Montgomery…
