Standard input-output norms for brake diaphragms under FTP require specified input proportions and mandate import-use alignment.

Standard input-output norms prescribe the composition and per-unit input proportions for brake diaphragms made of natural rubber containing a minimum sixty percent natural rubber, listing specific inputs such as nylon yarn, natural rubber, carbon black, zinc oxide, rubber chemicals, and miscellaneous chemicals. The framework requires determination and adherence to these input proportions in manufacture and obliges applicants to ensure imported goods are those used or required in the export product, so imports must correspond to declared input usage.
