We design and manufacture equipment for off-road use in the agriculture and industrial markets. We use an ASAE (American Society of Agricultural Engineers) standard for product validation. This standard is EP-455, which includes chemical resistance requirements and test methodologies to verify compliance. Hope this helps! Rick Vernon, QA Engineer Phoenix International Corp.

Does anyone know what possible industry specifications would or might cover this area? Even being pointed towards ANSI or Mil-Std's would be helpful! thank Doug
