Scope
GB/T 37252-2018 is the English-translated version of 氧传感器用片式氧化锆陶瓷元件.
GB/T 37252-2018 is the Chinese national product standard for the planar zirconia ceramic element at the heart of an automotive oxygen sensor. The element uses sheet zirconia ceramic as its working electrolyte and also carries a test electrode, a reference electrode, a heater, an insulating layer and an electrode protective layer.
The standard covers terms and definitions, requirements such as the 12 V to 14 V operating voltage range, test methods, inspection rules, and marking, packaging, transport and storage.
Its references point to environmental tests for free fall, sinusoidal vibration and salt spray, bending strength, density and porosity tests for fine ceramics, and sampling by AQL.
It applies to elements for oxygen sensors used with motor gasoline to GB 17930 or ethanol gasoline to GB 18351. It was issued on 28 December 2018 and has applied since 1 November 2019.
