ASTM Standards cover antimicrobial efficacy of solid copper.August 9, 2013 -
Subcommittee B05.06, part of ASTM Committee B05 on Copper and Copper Alloys, is developing ASTM WK42235, Test Method for Efficacy of Copper Alloy Surfaces as a Sanitizer; ASTM WK42244, Test Method for Residual Self-Sanitizing Activity of Copper Alloy Surfaces; and ASTM WK42247, Test Method for Continuous Reduction of Bacterial Contamination on Copper Alloy Surfaces. Developed in conjunction with EPA, standards will provide base for evaluation of antimicrobial efficacy of solid copper materials.
Three Proposed ASTM Standards to Cover Antimicrobial Efficacy of Solid Copper Materials

W. CONSHOHOCKEN, Pa., —Three proposed ASTM International standards will provide a base for the evaluation of the antimicrobial efficacy of solid copper materials. The proposed standards are being developed by Subcommittee B05.06, Methods of Test, part of ASTM International Committee B05 on Copper and Copper Alloys.
The three proposed standards are:
ASTM WK42235, Test Method for Efficacy of Copper Alloy Surfaces as a Sanitizer;
ASTM WK42244, Test Method for Residual Self-Sanitizing Activity of Copper Alloy Surfaces; and
ASTM WK42247, Test Method for Continuous Reduction of Bacterial Contamination on Copper Alloy Surfaces.
James Michel, manager, technical services, Copper Development Association Inc., and secretary of B05, says that the three proposed standards have been developed in conjunction with the U.S. Environmental Protection Agency to test the effectiveness of solid copper alloy surfaces to kill bacteria. Each of the proposed standards is a test method translated from an EPA protocol into the ASTM format.
“Previously, no test method has existed to qualify a solid material as a public health antimicrobial product,” says Michel. “Each of the proposed methods is different, but they are used together to qualify copper alloys as EPA-registered antimicrobial materials with human health claims.”
Michel notes that the foundation of the proposed standards will allow users throughout the world to quote and use the methods for testing procedures locally. “To the layman, the proposed standards will provide symbols that a material has been rigorously tested and proven to provide intrinsic antimicrobial benefits,” says Michel.
EPA copper alloys approved by use of these proposed methods will be available for such surfaces as door knobs and railings in healthcare facilities, schools and other public buildings, and transportation, to reduce bacteria and decrease the potential for infection. Primary users of ASTM WK42235, ASTM WK42244 and ASTM WK42247, once they have been approved, will be testing laboratories that want to qualify materials for potential EPA approval.
All interested parties are encouraged to join in the standards developing activities of Committee B05.
