1 Scope

This part of GB/T 36014 gives standard test methods for determining the technical parameters of radiation thermometers (hereinafter referred to as thermometers) for

The end user determines or confirms the basic measurement parameters of a single wavelength range and a single measurement field radiation thermometer. All these technical parameters

Provisions are made in GB/T 36014.1-2018.

In order to improve the comparability and testability of technical parameters, this part specifies a clear test to determine the technical parameters under standardized measurement conditions

The test method is used by skilled end users as a standard performance criterion for evaluating or selecting radiation thermometers.

For a specific type of radiation thermometer, manufacturers and sellers do not have to list all technical parameters given in this section in the parameter table

Number, just give the relevant parameters.

This section does not apply to infrared ear thermometers and infrared forehead thermometers.
