so for a project in europe we have recently been submitted a breakdown of VOC-content for a putty product which showed significantly different values depending on the testing method: DIN ISO 11890 5 g/L, ASTM D-3960-1 72.5 g/L.
Anyone have any experience / problems with this in review? Normally the VOC contents are simply quoted without testing method and we do not usually ask which method was used.
I cant find any requirement in the Ref Guide regarding testing method, but the SCAQMD Rules specify 3 possibilities: the U.S. EPA Reference Test Method 24; Method 303 in SCAQMD's "Laboratory Methods of Analysis for Enforcement Samples" manual, or Method 304 in SCAQMD's "Laboratory Methods of Analysis for Enforcement Samples" manual. Are these simply THE standards in the US which all products use?

Hi Victoria,
So, this is just my initial reaction but...I would think you would want to use the ASTM standard. My thoughts are that the DIN standard is German where the ASTM standard is more in line with the EPA and US standards. Also, it seems safest to go with the higher VOC level.
Let us know if you hear anything official on this.
Thanks,
Shannon
