This International Standard specifies a method for the determination of the pH of aqueous solutions of surface active agents. This method is applicable only if so indicated in the specific standard for each product.

 

This document specifies design, type testing, marking and manufacturing tests and examinations requirements for: a) self-closing cylinder valves; b) self-closing cylinder valves with integrated pressure regulator (VIPR), which include VIPR designs where the primary valve operating mechanism is located upstream of the pressure regulating system (VIPR type A) and where the primary valve operating mechanism is located at the low-pressure side of the pressure regulating system (VIPR type C); used for refillable transportable gas cylinders which convey compressed, liquefied or dissolved gases. NOTE 1 The main applications for such self-closing cylinder valves are in the calibration gas and beverage industries. NOTE 2 Where there is no risk of ambiguity, cylinder valves and VIPRs are addressed with the collective term “valves” within this document. This document does not apply to: — VIPR designs where the pressure regulating system is acting as the primary valve operating mechanism (VIPR type B) and designs where closure of the primary valve operating mechanism is obtained by closing the seat of the pressure regulating mechanism (such designs are covered by ISO 10297); — 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 contains normative references to this document; — ball valves. NOTE 3 Requirements for valves for cryogenic vessels are specified in ISO 21011 and at a regional level, e.g. in EN 1626. Requirements for valves for portable fire extinguishers are specified at a regional level, e.g. in EN 3 series. Requirements for self-closing LPG cylinder valves are specified in ISO 14245. Requirements for quick-release cylinder valves are given in ISO 17871. Requirements for ball valves are given in ISO 23826. This document only covers the function of a valve as a closure. NOTE 4 Other additional functions that can be integrated into the valve can be covered by other standards. Such standards do however not constitute requirements of this document. NOTE 5 Definition of and specific requirements for VIPRs in addition to those given in this document are specified in ISO 22435 for industrial applications or ISO 10524-3 for medical applications. Similarly, certain specific additional requirements for residual pressure valves (RPV) are given in ISO 15996.

 

ISO 17879:2017 specifies the design, type testing, marking and manufacturing tests and examinations requirements for self-closing cylinder valves intended to be fitted to refillable transportable gas cylinders which convey compressed, liquefied or dissolved gases. NOTE 1 The main applications for such self-closing cylinder valves are in the calibration gas and beverage industries. ISO 17879:2017 covers the function of a self-closing cylinder valve as a closure. NOTE 2 Requirements for standard cylinder valves are given in ISO 10297. Requirements for quick-release cylinder valves are given in ISO 17871. ISO 17879:2017 is not applicable to self-closing cylinder valves for cryogenic equipment, for portable fire extinguishers, or for liquefied petroleum gas (LPG). NOTE 3 Requirements for valves for cryogenic vessels are specified in ISO 21011 and at a regional level, for example, in EN 1626. Requirements for valves for portable fire extinguishers at a regional level are specified, for example, in EN 3 series. Requirements for self-closing LPG cylinder valves are specified in ISO 14245. NOTE 4 Additional requirements for pressure-relief devices might be specified in international/regional regulations/standards.

 

This document defines various terms relating to the design, construction, primary packaging and testing of fireworks of categories F1, F2 and F3 as defined by Article 6 Paragraph (1) clause (a) subclause (i) to (iii) of Directive 2013/29/EU. It gives descriptions of fireworks types and establishes a system for categorization. Minimum labelling requirements for fireworks as well as for primary and selection packs of fireworks are specified. Firework specific test methods are defined. Specifications of requirements for construction and performance of firework, primary packs and selection packs complete this standard. This standard does not apply to fireworks intended to be kept or used at temperatures below -20 °C or above 50 °C.

 

This document provides technical specifications on categories, operations, safety management and risk analysis of the use of proximity pyrotechnic articles. This document provides technical reference on the technologies of close proximity pyrotechnic articles. This document aims to provide technical guidance for the protection of property, operators, performers, auxiliary personnel, and audience safety when using pyrotechnic articles effects at close range indoors or outdoors, and to provide technical reference for proximity pyrotechnic article shows. This document applies to the use of proximity pyrotechnic articles in front of the nearest audience, performers, or supporting personnel for performing arts in conjunction with drama, music, or similar works. This document applies to the performance specifications, usage instructions, notifications, and labelling of manufacturers of pyrotechnic materials, instruments, equipment, and supplies. This document applies to any indoor use of proximity pyrotechnic articles.

 

This document defines the procedures for classifying, testing and labelling of cartridges for powder actuated tools (PAT cartridges), as defined in Clause 3 of this document. This document applies to PAT cartridges which are all classified as P1. This document does not apply to pyrotechnic articles containing blasting agents and military explosives except black powder and flash composition. PAT cartridges contain pyrotechnic composition(s) delivering mainly gases, intended to propel a piston. The piston propels fasteners (e.g. nails) or drives hard marking characters into appropriate materials. This document also applies to PAT cartridges sold to persons younger than 18 years, if this is permitted by the Member State due to the low hazard of the PAT cartridges. NOTE PAT cartridges can also be used for hard marking tools. Information on cartridge operated fixing and hard marking tools can be found in EN 15895:2025 [1]. This document applies to the cartridges listed in Table 1. Table 1 — Lists of the established calibres for PAT cartridges

 

ISO 17516:2014 is applicable for all cosmetics and assists interested parties in the assessment of the microbiological quality of the products. Microbiological testing does not need to be performed on those products considered to be microbiologically low risk.
