Input-output norms for three-phase electrical energy meters require specified input materials and verification that imported inputs are used in exports.

Input output norms for Three Phase Electrical Energy Meter set permissible inputs (aluminium, MS and CRNGO sheets, copper wire or electrolytic copper, stainless steel, magnets, plastics/rubbers, bearing assemblies) with specific content by weight ratios or net to net measures. Applicants must determine the proportion of inputs required for manufacture and ensure imported goods are those actually used in the export product; compliance and verification of use are required to rely on the stated norms.
