Aluminium and aluminium alloys. Chemical analysis. Sampling from metal melts Ingestion-build-228203 Fireman’s switches complying with BS1 Scope This document specifies criteria for sampling and gives guidance on the sampling from melts in order to verify if the chemical composition of the product fabricated from a metal melt is in conformance with the specification. NOTE For sampling from product or laboratory samples see EN 14242 or prEN 14726.
