It does not apply to nuts requiring properties such as:

Note: BS EN 1888-1 European Standard does not cover toys

Note 3: Copper and alloys containing a high percentage of copper are heavily tarnished in the test atmosphere owing to the formation of copper sulphides

Requirements of population and resistance (clause 9) revised

E39 are excluded as they do not comply with European safety requirements

Workplace air. Determination of hexavalent chromium in airborne particulate matter. Method by ion chromatography and spectrophotometric measurement using diphenyl carbazide Ingestion-build-109673 It does not apply to1 Scope This International Standard specifies a method for the determination of the time weighted average mass concentration of hexavalent chromium in workplace air. Separate sample preparation methods are specified for the extraction of soluble and insoluble hexavalent chromium. The method for insoluble hexavalent chromium can also be used to prepare samples for determination of total hexavalent chromium, if desired. This International Standard is
