I have never heard of those two, and a quick search of Techstreet shows a couple of things BS EN 13496:2002 -- Thermal insulation products for building applications. Determination of the mechanical properties of glass fibre meshes and ISO 13496:2000 -- Meat and meat products - Detection of colouring agents - Method using thin-layer chromatography
DIN 16937 -- Plasticized polyvinyl chloride (PVC-P) waterproofing sheet compatible with bitumen; requirements
So, I am not sure. But also keep in mind that ISO 9002 has been obsolete for a while, so I am not sure where the recruiter was going.
