Gas cylinders - Cylinder valves with integrated pressure regulators - Specification and type testing (ISO 22435:2024)
kSIST FprEN ISO 22435:2024

This document specifies design, type test methods, marking and instruction requirements for cylinder valves with integrated pressure regulators (VIPRs) intended to be fitted to gas cylinders, pressure drums or tubes or used as a main valve for bundles of cylinders that convey compressed, liquefied or dissolved gases.
These are requirements for VIPRs that are in addition to those given in the relevant closure standard, for example, in ISO 10297 for cylinder valves, in ISO 17871 for quick-release cylinder valves, in ISO 17879 for self-closing cylinder valves or in ISO 23826 for ball valves. For ISO 17871, these requirements are only applicable to quick-release cylinder valves types B, C, D and E.
NOTE 1        If the pressure regulating system of a VIPR is acting as the primary valve operating mechanism, it is covered by the relevant closure standard, e.g. ISO 10297, ISO 17871, ISO 17879 and ISO 23826. 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 system.
NOTE 2        If the primary valve operating mechanism of a VIPR is located at the low-pressure side of the pressure regulating system, it is covered by the relevant closure standard, e.g. ISO 10297, ISO 17871, ISO 17879 and ISO 23826.
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 VIPRs for
a)       medical applications (see ISO 10524-3);
b)       liquefied petroleum gas (LPG);
c)        cryogenic applications.
NOTE 4        Additional requirements for a VIPR with a residual pressure device (RPD) are specified in ISO 15996.
NOTE 5        Additional requirements for pressure relief valves can exist in international/regional regulations/ standards.

Safety and control devices for burners and appliances burning gaseous and/or liquid fuels - Valve proving systems for automatic shut-off valves
SIST EN 1643:2023

EN 13611:2019, Clause 1 is replaced by following:
This document specifies the safety, design, construction and performance requirements, and testing for valve-proving systems, hereafter referred to as “VPS”, intended for use with gas burners and gas-burning appliances burning one or more gaseous fuels.
This document applies to all types of VPS used for the automatic detection of leakage in a gas burner section having at least two automatic shut-off valves, and which give a signal if the leakage of one of the valves, the piping in-between the valves or of the VPS itself and its components exceeds the detection limit.
This document applies to VPS for gases with a maximum inlet pressure up to and including 500 kPa.
This document does not apply to VPSs for use in explosive atmospheres.
This document is applicable to AC and DC supplied VPS (for VPS supplied by stand-alone battery system, battery systems for mobile applications, or VPS which are intended to be connected to DC supply networks, see Annex I).

Safety and control devices for burners and appliances burning gaseous or liquid fuels - Control functions in electronic systems - Part 2: Fuel/air ratio control/supervision of the electronic type
SIST EN 12067-2:2023

EN 13611:2019, Clause 1 is replaced by the following:
This document specifies the safety, design, construction and performance requirements, and testing for electronic fuel/air ratio control systems (ERC), electronic fuel/air ratio supervision systems (ERS) and electronic fuel/air ratio trim systems (ERT) intended for use with burners and appliances burning gaseous or liquid fuels. It also describes the procedures for evaluating these requirements and specifies information necessary for installation and use.
This document is applicable to:
-   closed loop fuel/air ratio control systems, see 3.101;
-   fuel/air ratio supervision systems, see 3.102;
-   closed loop fuel/air ratio trim systems, see 3.103;
and does not differentiate into classification by heat input.
NOTE   The documents for burners, appliances or processes which use ERC, ERS or ERT can override the requirements of this document.
