The Engine is the heart of the automobile power system, with the complex structure, and the number of parts, the stable work needs all parts have good reliability. So the quality of the oil pressure sensor is the most core problem.
Our Pressure sensor factory has been focusing on the R&D and production of pressure sensors, temperature sensors, fuel level sensors, speed sensors etc… over 25 years of pressure sensor professional technical experience… has been obtained the QC/T822-2009, ISO/TS16949, RoHs and Reach Certificates.
So today let,s us to know : Automobile industry standard of the People’s Republic of China
Standard numbe:r QC/T 822-2009 Engine oil pressure sensor for automobile
Release date: November 17, 2009 The implementation date is April 01, 2010 Expiration date none
China Standard classification number T35
International Standard Classification number 43.040.10
Release unit industry standard – Automotive
Step 1: Scope :
This standard specifies the requirements, test methods, inspection rules and marks, packaging, storage and custody of engine oil pressure sensors for automotive (hereinafter referred to as sensors).
This standard applies to engine oil pressure sensors for automotive applications. Other motor vehicle engine oil pressure sensors can also refer to the execution.
