ASTM D6440-01

Standard Terminology Relating to Hydrocarbon Resins

SCOPE
1.1 The hydrocarbon resin industry continues to evolve from a source of replacement products for naturally-derived materials to industrial materials that have no naturally-derived counterparts. Along with this changing character of the industry, various manufacturing participants have introduced terms that have led to confusion among both manufacturers and consumers. This terminology standard is intended to alleviate that confusion and promote standard usage of terms in the hydrocarbon resin industry.
1.2 Resins derived principally from natural terpene fractions are under the jurisdiction of D01.34.
