The performance aspects of this Specification are derived from long-term studies and tests of the BDM product, but are issued for guidance only. Any proposed use of the BDM zipper range must be fully tested by the user and no warranty is issued against failure of the zipper in new or old applications based purely upon the above figures, especially in life-threatening situations.

Field Trials are ESSENTIAL

The New Zipper Company disclaims any liability for failure of, or subsequent losses resulting from the use of, the BDM product range where production error by NZ cannot be irrefutably proven. The New Zipper Company reserves the right to change any or all of the above specification in the continuing search for product improvement. *(NOTE: 10 pitch zippers are not recommended for clothing applications.)*
