Animal and vegetable fats and oils. Determination of fatty-acid-bound chloropropanediols (MCPDs) and glycidol by GC/MS - Method using acid transesterification and measurement for 2-MCPD, 3-MCPD and glycidol1 Scope This document specifies a procedure for the simultaneous determination of 2 MCPD esters (bound 2 MCPD), 3MCPD esters (bound 3MCPD) and glycidyl esters (bound glycidol) in a single assay, based on acid catalysed ester cleavage and derivatization of cleaved (free) analytes with phenylboronic acid (PBA) prior to GC MS analysis. This document is applicable to solid and liquid fats and oils. For all three analytes the limit of quantification (LOQ)

It defines general procedures for quality assessment to be used in the IECQ System and gives general rules for:

The scope was widened to encompass a wider range of stud design

Why should you use PD IEC/TS 62229 - Multimedia e-publishing and e-book standards

users can assess the purity of urea fertilizers and prevent interference with nitrogen metabolism and protein synthesis in plants

BS 3641-2 and BS 3641-3

e)      Added information on uninterruptable power supplies

BS EN 12977-4 applies to combistores with a nominal volume up to 3 000 l and without integrated burner

Why should you use BS 4480-2 - Solid plastics bushes for plain bearings

That has been corrected
