JB/T 6771-1993 is a recommended Chinese mechanical and machinery industry standard that gives the test method for the thermal adaptability of spark plugs chosen for automobile and motorcycle engines. It describes how a plug is tested to establish whether its heat range suits the engine it has been selected for. The method is written for automobile and motorcycle engines, while tests on spark plugs for special vehicles fall outside it. It quotes JB 3743, ZB T81 001, GB 5363 and GB 7825, and it carries the Chinese classification T37. Issued on 21 August 1993, it has applied since 1 October 1993.
