This document specifies design, type testing and marking requirements for:
a) cylinder valves intended to be fitted to refillable transportable gas cylinders;
b) main valves (excluding ball valves) for bundles of cylinders;
c) cylinder valves or main valves with integrated pressure regulator (VIPR);
NOTE 1 This includes the following specific VIPR designs where:
1) the pressure regulating system of a VIPR is acting as the primary valve operating mechanism (VIPR type B). This also includes designs where closure of the primary valve operating mechanism of a VIPR is obtained by closing the seat of the pressure regulating mechanism.;
2) the primary valve operating mechanism of a VIPR is located at the low pressure side of the pressure regulating system (VIPR type C).
d) valves for pressure drums and tubes;
which convey compressed, liquefied or dissolved gases.
NOTE 2 Where there is no risk of ambiguity, cylinder valves, main valves, VIPR and valves for pressure drums and tubes are addressed with the collective term “valves” within this document.
NOTE 3 The term “pressure receptacle” is used within this document to cover instances where no differentiation is necessary between gas cylinders, bundles of cylinders, pressure drums and tubes.
This document does not apply to
— valves for cryogenic equipment, portable fire extinguishers and liquefied petroleum gas (LPG);
— quick-release cylinder valves (e.g. for fire-extinguishing, explosion protection and rescue applications) - requirements for quick-release cylinder valves are specified in ISO 17871 which nevertheless contains normative references to this document;
— self-closing cylinder valves or ball valves.
NOTE 4 Requirements for valves for cryogenic vessels are specified in ISO 21011 and at a regional level, e.g. in EN 1626. Requirements for LPG valves are specified in ISO 14245 or ISO 15995. Requirements for self-closing cylinder valves are specified in ISO 17879. Requirements for ball valves are specified in ISO 23826. Requirements for valves for portable fire extinguishers at a regional level are specified e.g. in EN 3 series.
This document only covers the function of a valve as a closure. Other functions that are possibly integrated in the valve can be covered by other standards. Such standards do however not constitute requirements according to this document.
NOTE 5 Definition and specific requirements for VIPR in addition to those that are given in this document are specified in ISO 22435 for industrial applications or ISO 10524‑3 for medical applications. Similarly, certain specific requirements for residual pressure valves (RPV) with or without a non-return function in addition to those that are given in this document are given in ISO 15996.
NOTE 6 Certain specific requirements for valves for breathing apparatus in addition to those that are given in this document are specified at a regional level, e.g. in EN 144 series. Certain specific requirements for quick-release valves for fixed fire-fighting systems in addition to those that are given in this document are specified in ISO 16003 and at a regional level e.g. in EN 12094–4.
NOTE 7 Additional requirements for pressure-relief devices can exist in international/regional regulations/standards.
NOTE 8 Requirements for manufacturing tests and examinations of valves covered by this document are given in ISO 14246.
This document establishes terminology for AI and describes concepts in the field of AI.
This document can be used in the development of other standards and in support of communications among diverse, interested parties or stakeholders.
This document is applicable to all types of organizations (e.g. commercial enterprises, government agencies, not-for-profit organizations).
This document establishes an Artificial Intelligence (AI) and Machine Learning (ML) framework for describing a generic AI system using ML technology. The framework describes the system components and their functions in the AI ecosystem. This document is applicable to all types and sizes of organizations, including public and private companies, government entities, and not-for-profit
organizations, that are implementing or using AI systems.
This document specifies the required characteristics, tests and tooling applicable to female electrical contacts 071, type A, crimp, class S used in elements of connection according to EN 3155-002.
It shall be used together with EN 3155-001.
The associated male contacts are specified in EN 3155-008 and EN 3155-070.
This document specifies the rack and panel rear mounted plug 2 and 4 modules, series 3 used in the family of rectangular electrical connectors. The receptacles corresponding to those plugs are specified in EN 4165-002.
This document specifies safety requirements and test methods for all types of load sharing devices commonly used in mountaineering (climbing and associated activities) and rescue.
This standard does not cover the specific requirements of devices intended for use in slackline applications.
Adoption of ISO 13004:2022 – This is currently in FDIS and will be publishing in October 2022.
This document describes a method for substantiating a selected sterilization dose of 17,5,
20, 22,5, 27,5, 30, 32,5 or 35 kGy that achieves a sterility assurance level (SAL) of 10−6 or less for radiation
sterilization of health care products. This Technical Specification also specifies a method of sterilization
dose audit used to demonstrate the continued effectiveness of the substantiated sterilization dose.
NOTE Selection and substantiation of the sterilization dose is used to meet the requirements for establishing
the sterilization dose within process definition in ISO 11137-1.
This International Standard specifies the determination of phytase activity in feeding stuff samples, including feed raw materials from plant origin, compound feeds (complete, complementary, mineral feeds), premixtures and feed additives.
The method is collaboratively validated for the determination of phytase activity in complete feed, complementary feed including mineral feed, premixtures and feed additives.
The method does not distinguish between phytase added as a feed additive and endogenous phytase already present in the feed materials. Therefore, the method is also applicable for feed materials from plant origin.
The method cannot be used to evaluate or compare the in vivo efficacy of the phytase product. It is not a predictive method of the in vivo efficacy of phytases present on the market as they can develop different in vivo efficacy per unit of activity.
Note 1: Products which are not included in the validation studies in the Annexes have to be checked especially on their linearity of response (release of phosphorus)
This document specifies a gas chromatography and a mass spectrometry method of detecting the presence of argon in metal powder produced components, consolidated by hot isostatic pressing.
This document specifies the calibration and functionality test for the equipment covered. It also specifies methods for sampling, sample preparation and sample test procedure of PM HIP components to detect argon presence.
Components produced by additive manufacturing are not covered in this document.
ISO 10563:2017 specifies a method for the determination of the change of mass and the change of volume of self-levelling and non-sagging sealants used in joints in building construction.
