Proposed New Standard Provides Specification for Secondary Prime Western Grade Zinc

A proposed new ASTM International standard will provide a definable quality specification for both producers and consumers of secondary prime western grade zinc metal. WK16399, Specification for Prime Western Zinc Metal Produced from Recycled Zinc Secondary Material, is being developed by Subcommittee B02.04 on Zinc and Cadmium, part of ASTM International Committee B02 on Nonferrous Metals and Alloys.

According to Larry Parkinson, retired president, Interamerican Zinc Inc., and secretary, Committee B02, prime western grade zinc produced by recycling zinc secondary materials is not currently covered by other B02.04 standards such as B6, Specification for Zinc, and B852, Specification for Continuous Galvanizing Grade (CGG) Zinc Alloys for Hot-Dip Galvanizing of Sheet Steel. Consumers of this type of zinc include fabrication hot dip galvanizers who produce products such as guardrails, electric poles, pipes and beams.

Parkinson says that all interested parties are welcome to participate in the development of WK16399.
