Scope

GB/T 33706-2017 is the English-translated version of 标准直接辐射表.

GB/T 33706-2017 is the Chinese standard for the standard pyrheliometer, the reference instrument for direct solar radiation. It fixes the composition of the instrument, its technical requirements, the test methods, the inspection rules, the test and calibration cycle, marking, packaging, transport and storage, and the accompanying documents.

Clause 3 defines zero offset, tilt response, solar altitude angle and the absolute cavity radiometer, a self-calibrating instrument with a cavity receiver.

Four annexes classify the environmental conditions, set the electromagnetic compatibility requirements and test methods, give performance requirements for the equipment used to test radiation sensors, and give the environmental test methods.

It applies to the design, manufacture and acceptance of standard pyrheliometers. It was issued on 12 May 2017 and has applied since 1 December 2017.
