Fluorocarbon Feedstock Grade Chloroform
Producers of fluorocarbons are invited to join in the ongoing standards developing activities of ASTM International Committee D26 on Halogenated Organic Solvents and Fire Extinguishing Agents. The committee has recently approved a new standard, D7509, Specification for Fluorocarbon Feedstock Grade Chloroform, under the jurisdiction of Subcommittee D26.08 on Halogenated Organics Used as Feedstocks.
Producers of feedstock for the fluorocarbon business as well as fluorocarbon producers themselves will be users of D7509, according to Douglas Terry, chair of Committee D26. “Until fairly recently, most feedstock was produced in the U.S. and Europe,” says Terry. “Now we are seeing more being produced in Asia for use in that area. It’s an international market and ASTM produces international standards. It makes sense now to have international standards for these feedstocks. Chloroform is a major feedstock, so we started with it.”
Committee D26 plans to continue to develop feedstock standards. “We are certainly interested in participation by the users, the fluorocarbon producers from both the manufacturing view (specifications) and analytical (test methods),” says Terry. “We have participation by some producers, but we would like to see more of that also, and we certainly welcome general interest.”
