Imperfections in thermoplastic welds. ClassificationWhat is this standard about? This document specifies a system for classifying imperfections that may be encountered in thermoplastic welded joints during manufacture and provides examples of imperfections for the following welding processes: heated tool butt welding; heated tool socket welding; electrofusion socket welding; hot gas welding; extrusion welding; solvent socket welding. This document does not describe imperfections that may be generated

Note: BS 7121-2-4 does not cover the stability testing and certification immediately following installation of loaders cranes on vehicles

It gives recommendations on reducing energy consumption and maintaining energy efficiency in new and existing cleanrooms and clean air devices

2 % non-proportional elongation and rounding rules have been added

Industrial and hospital articles may be subjected to special laundering procedures which may be more severe in some respects

steel sourced from (scrap-based) steel recycling can be made to the same specification as steels sourced from the (iron ore based) primary routes

The objective of the standard is to specify the method for demonstration of compliance with the specific absorption rate (SAR) limits for such equipment
