BS 4401 is a European standard on methods of test for meat and meat products that discusses the determination of starch and glucose contents in meat and meat products to ensure meat and meat products are safe for consumption

This British Standard a part of the BS 8000 series

the IEC recommends its use as a means for the calibration of specified vibrators used in audiometry and for the exchange of specifications and of data on bone conduction hearing aids

of elastomer pressure springs intended for use in press tools

Cosmetics. Analytical methods. Validation criteria for analytical results using chromatographic techniques Ingestion-build-79769 BS EN 4250 on nickel1 Scope This International Standard defines validation criteria with which analytical results obtained from the analysis of cosmetic products should comply in order to give confidence in performance, reliability and quality of the final result. It sets out an analytical approach that can be used by a single laboratory to carry out chromatographic analyses on a given sample, or samples.
