FINAL PUBLIC NOTICE: ISRI Proposed Changes to SHELMO and ROPES Specifications

(Washington, DC) – The Institute of Scrap Recycling Industries (ISRI) Board of Directors approved amendments to existing nonferrous specifications for shredded electric motors (SHELMO) and wheel weights (ROPES) at its Winter Meeting on February 1. These specification changes are intended to more accurately reflect the nonferrous scrap commodities currently being traded in the marketplace.

The proposed modifications:

1) Change the maximum allowable amount of aluminum-wound material in the SHELMO specification from 10 percent to 5 percent; and

2) Change the ROPES specification title from “Wheel Weights” to “Lead Wheel Weights.”

As per ISRI’s Policy Manual, any party may submit to ISRI a written appeal of the ISRI Board’s approval of these changes up to 30 days after publication of this notice. Written appeals must provide a rationale and a request for action. Once finalized, the new specification will be included in ISRI’s Scrap Specifications Circular. ISRI’s Scrap Specifications Circular provides industry guidelines for buying and selling a variety of processed scrap commodities, including ferrous, nonferrous, paper, plastics, electronics, rubber, and glass.
