BS EN 12163 is a European standard on copper and copper alloy that discusses the criteria for manufacturing copper alloy rods of various shapes

Part 1 of this standard covers the general requirements of soil testing relating to civil engineering

The scope of PD IEC TS 62351‑100‑1 is to specify commonly available procedures and definitions for conformance and/or interoperability testing of IEC TS 62351-5 and IEC TS 60870-5-7

Leather. Chemical determination of formaldehyde content - Method using colorimetric analysis Ingestion-build-156411 7 Extending ISO/IEC 15408 evaluationWhat is this standard about? This document specifies a method for the determination of free and released formaldehyde in leathers. This method, based on colorimetric analysis, is not intended to be used for a precise quantification of formaldehyde. The formaldehyde content is taken to be the quantity of free formaldehyde and formaldehyde extracted through hydrolysis contained in a water extract from the leather under standard conditions. This process
