The lawsuit removed ASTM D-1692, Bunsen burner test, when measuring burn characteristics, and required the currently used ASTM E 84 test method of surface burning characteristics be used as a testing standard. It was also a key factor in the establishment of Section 1717 of the 1976 Uniform Building Code and has been used in every subsequent edition.
NPG or Neopentyl Glycol is another material we see a lot in customer specs. NPG is typically used with powder coating resins to increase weather ability and thermal UV stability or with liquid gel coats in boats and kitchen & bath fixtures. At Shelter Works, we use liquid gel coats that already provide superior resistance to ultraviolet deterioration and hydrolysis. Although we can meet specs that require NPG easily enough, unless your project is for a waste water application or located in a marine environment, having Neopentyl Glycol required by your spec only adds unnecessary costs to your project.
Clearly written, updated and correctly worded specifications have a direct impact on the cost and accuracy of your project. At Shelter Works, we work with our customers to review and make recommendations regarding specifications. In some cases we have developed specifications tailored to the individual job for our customers, saving them time, money and headaches.
