AKRON (Aug. 2, 2011)—Akron Rubber Development Laboratory Inc. has added ASTM D 5712 and ASTM D 6499 standards to the scope of its accredited tests.
D 5712 is the “Standard Test Method for Analysis of Aqueous Extractable Protein in Natural Rubber and its Products Using the Modified Lowry Method. It is used to determine the total extractable protein content from rubber products.
D 64999 is the “Standard Test Method for the Immunological Measurement of Antigenic Protein in Natural Rubber and its Products.” It is used to quantifiy the level of Hevea proteins.
ARDL said it is using the two testing methods as the basis for its natural rubber latex allergy product evaluation program and will be under the firm's newly established Microbiology laboratory being directed by David Kostyal, ARDL's senior microbiologist. The lab focuses on latex protein testing and biocompatibility assays and further expands the company's capabilities in the microbiological field.
