EN 71-1:2014 on the safety of toys supersedes BS EN 71-1:2014 and combines three amendments into one which covers:

Developing strategies to minimize obsolescence during the design

BS EN 980:2008 also provides examples of how symbols can be used and the information they convey

Water quality. Determination of phosphorus. Ammonium molybdate spectrometric method PAS 15 safe and standardized starter batteries1 Scope This International Standard specifies methods for the determination of orthophosphate (see Clause 4); orthophosphate after solvent extraction (see Clause 5); hydrolysable phosphate plus orthophosphate (see Clause 6); total phosphorus after decomposition (see Clauses 7 and 8). The methods are applicable to all kinds of water including seawater and effluents. Phosphorus concentrations within the range of 0,005 mg l to 0,8 mg l may be determined
