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 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

This part of ISO 6142 specifies a gravimetric method for the preparation of calibration gas mixtures in cylinders with traceable values for the amount-of-substance fraction (amount fraction) of one or more components. This part of ISO 6142 describes a method for calculating the uncertainty associated with the amount fraction of each component. This uncertainty calculation requires the evaluation of the contributions to the uncertainty due to factors including the weighing process, the purity of the components, the stability of the mixture, and the verification of the final mixture.This part of ISO 6142 is only applicable to mixtures of gaseous or totally vaporized components, which may be introduced into the cylinder in the gaseous or liquid state. Both binary and multi-component gas mixtures (including natural-gas type mixtures) are covered by this part of ISO 6142. Methods for the batch production of more than one mixture in a single process are not included in this part of ISO 6142.This part of ISO 6142 requires estimation of the stability of the mixture for its intended life time (maximum storage life), but it is not for use with components that react with each other unintentionally. This part of ISO 6142 also requires the impurities in each parent gas or liquid used in the preparation of the mixture to be assessed and quantified.
