1 Scope 1.1 This Standard sets forth minimum requirements for emergency breakaway fittings, swivel connectors and pipe-connecting fittings of the threadless compression type. Connectors and fittings covered by these requirements are intended only for the following services. 1.2 A swivel connector is either a hose swivel or swivel joint. The swivel connector will allow radial movement and is…

This document specifies a method for the determination of certain cyclic volatile methylsiloxanes (cVMS) in environmental water samples with low density polyethylene (LDPE) as a preservative and subsequent liquid-liquid extraction with hexane containing 13C-labeled cVMS as internal standards. The extract is then analysed by gas chromatography-mass spectrometry (GC-MS). NOTE Using the 13C-…

This document specifies the geometry of test specimens and the testing procedure for mechanized peel testing of single mechanical joints on single-lap test specimens up to a single sheet thickness of 4,5 mm. The term "sheet", as used in this document, includes extrusions and cast materials. The purpose of the mechanized peel tests is to determine the mechanical characteristics and the…

This document specifies the common requirements for sterilizers used for terminal sterilization of medical devices in health care facilities. This document covers sterilizers that operate with a variety of sterilizing agents (alone or in combination) within a sealed vessel at different temperatures, above, at, or below atmospheric pressure. This document provides high-level requirements and…

1.1 These requirements cover pressure regulators for use with LP-Gas equipment. NOTE: For the purposes of this standard the terms “LP-Gas” and “Propane” are interchangeable. 1.2 Regulators covered by these requirements are intended to be installed and used in systems in accordance with the applicable Codes and Regulations as determined by the Authority Having Jurisdiction (AHJ), such as, but…

IEC 61800-1:2021 applies to adjustable speed electric DC power drive systems, which include semiconductor power conversion and the means for their control, protection, monitoring, measurement and the DC motors. It applies to adjustable speed electric power drive systems intended to feed DC motors from a BDM/CDM connected to line-to-line voltages up to and including 1 kV AC 50 Hz or 60 Hz and/or…

This document gives guidelines for the development of multi-operator/multi-service interoperable public surface (including subways) transport fare management systems (IFMSs) on a national and international level. This document is applicable to bodies in public transport and related services which agree that their systems need to interoperate. This document defines a conceptual framework which is…

IEC 60433:2021 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 60433:2021 is applicable to string insulator units of the long rod type with insulating parts of ceramic material…

IEC 62977-2-1:2021(E) specifies standard measurement conditions and measuring methods for determining the optical characteristics of electronic display modules and systems. These methods apply to emissive and transmissive direct view displays that render real 2D images on a flat panel. This document evaluates the optical characteristics of these displays under darkroom conditions. This document…

1 Scope 1.1 This Standard outlines requirements for low slope membrane roofing systems (LSMRS) when identified as “silver” and “gold” performance level based on the climate severity and resilience requirements. Note: The National Building Code of Canada and the National Energy Code of Canada for Buildings provides “bronze” requirements for LSMRS. 1.2 This Standard is intended to be used by…
