Scope

GB/T 33905.5-2017 is the English-translated version of 智能传感器第5部分：检查和例行试验方法.

GB/T 33905.5-2017 is Part 5 of GB/T 33905 and gives the inspection and routine test methods for intelligent (smart) sensors. It covers the sampling of sensors for test, general inspection - appearance and insulation resistance - functional inspection, performance testing, and the test reports and documentation to be issued.

Sampling may follow a method agreed between user and manufacturer, and routine tests are normally run on every unit.

The appearance check asks for a complete and clean sensor with stable moving parts, no significant corrosion, dents, scratches or coating defects, clear and complete markings and nameplate, correctly assembled and reliably connected parts, and correct mechanical and electrical interfaces.

It applies to smart sensors that convert one or more physical or chemical quantities into a digital signal for use in a communication network, or into an analogue electrical signal.

Terms and the performance test methods it calls up come from GB/T 2900.56, GB/T 18271.1-2017, GB/T 18271.2 and GB/T 33905.4-2017. The series has five parts: general principles, IoT application rules, terms, performance evaluation methods and this one. Issued on 31 July 2017, it has applied since 1 February 2018.
