This document applies to acetylene manifold systems extending from the cylinder valve or the bundle outlet connections to the outlet connection of the main shut-off valve. It specifies requirements for design, materials and testing of cylinder manifold systems for the supply of acetylene for use in welding, cutting and allied processes. This document applies to acetylene manifold systems in which one of the following acetylene sources is used or connected for collective gas withdrawal: — Single individual cylinder; — Multiple cylinders; — Single individual bundle; — Multiple bundles, When a single individual cylinder with cylinder regulator according to ISO 2503 is directly connected to the cylinder valve, this document does not apply. NOTE National regulations exist regarding limitation of the amount of single cylinders/bundles of acetylene on a single location (e.g. in warehouse or connected to a manifold system).

 

This document specifies a method for determination of tuft withdrawal force and is applicable to all textile floor coverings with a cut and/or loop pile yarn structure.

 

This document establishes a classification system for resilient, textile, laminate and modular mechanical locked floor coverings. The classification is based on practical requirements for areas of use and intensity of use and is linked to the requirements specified in the relevant documents for each type of floor covering. This document is also intended to provide guidance for manufacturers, specifiers and consumers, to enable them to choose the appropriate class of floor covering for any given area of use or specific room. NOTE The wear and appearance of floor coverings are influenced by standards of installation and maintenance, the condition of the subfloor and the kind of use (type of footwear, high concentrations of localized traffic, etc.). These factors are intended to be taken into account when using this classification system.
