JIG, short for Joint Industry Guide, is a guideline established jointly by the member companies of EICTA (European Information, Communications and Consumer Electronics Technology Industry Association), JGPSSI (Japan Green Procurement Survey Standardization Initiative), EIA (Electronic Industries Alliance of the US) and JEDEC (Joint Electron Device Engineering Council of the US). It regulates the materials and chemicals contained in electrical and electronic equipment that suppliers must disclose, as well as their threshold values.
