Standard Input-Output norms prescribe allowable composition and input quantities for manufacture of Low Voltage Porcelain Insulators, listing required raw materials and permitted additives by proportion. These norms function as the regulatory benchmark for assessing that imported inputs are those used or required in the export product; applicants must ensure declared imports conform to the listed inputs and proportions.
