All samples shall produce curves that correspond to the reference standard when tested under the same conditions as those specified on the master curve, and it must be neoprene. 3.10 SUPPLIERS RESPONSIBILITY Material supplied to this

9、specification must be equivalent to that originally approved. Changes in formulation or processing shall not be made without prior approval as described in Supplier Procedure I-A. 4. APPROVAL OF SUPPLIERS: Suppliers to this specification must be approved by the affected product engineering office. Procedure for gaining approval of a specific material to a new/existing ES-M specification is contained in Supplier Procedure I-A. Approved new suppliers will be added to the Engineering Materials Approved Source List.
