Never trust an internal testing or QC certification from the supplier directly. Always insist for a trustable/accreditated 3rd party lab testing.
However in this case, as you can see highlighted, it's common that a fastener company without any real QC or professional experience in standards has just published they clearly do not comply(probably in honest truth) whereby their own QC has verified that they do not meet the AS3566 standards while claiming to do so. The standard clearly stated min.(minimum) 25 microns zinc-tin, how does >15 microns seem as a PASS when the standard which they also published here clearly says minimum 25 microns to pass?
