Specification and qualification of welding procedures for production welding of steel castings
ISO 11970:2016 specifies how a welding procedure specification (WPS) for production welding of steel castings is qualified.
It defines the conditions for the execution of welding procedure qualification tests and the limits of validity of a qualified welding procedure for all practical welding operations within the range of essential variables.
Tests are intended to be carried out in accordance…
Microbiology of the food chain — Detection, isolation and characterization of Shiga toxin-producing ...
This standard describes the detection and isolation of Shiga toxin-producing Escherichia coli (STEC). The procedure includes the detection by Real Time PCR of the major virulence genes of STEC, stx1 and stx2 (Reference [2]) in enrichment cultures. Isolation of STEC from the enrichment culture is attempted if one or both stx genes are detected in the screening.
