Standard Input Output Norms govern permitted inputs for manufacture of FR-type laminates, requiring imported inputs match export product use.

Standard Input-Output Norms prescribe permissible inputs and their proportions for manufacture of Copper Clad Glass Epoxy Laminate (FR-4) single-sided and double-sided of thickness 3.2mm, listing component quantities for copper foil, glass fabric, epoxy resin, thinners and solvents, hardeners, accelerators, release film and padding paper, with measures for single- and double-sided products. Applicants must determine input proportions used in manufacture and ensure imported goods correspond to inputs used or required in the exported product.
