Defines traceable calibration methods of black-standard thermometers (BST), white-standard thermometers (WST), black-panel thermometers (BPT) and white-panel thermometers (WPT) for use in natural and artificial weathering: - method A, a contact method, uses a traceable calibrated resistance standard thermometer; - method B, a contactless method, uses a traceable calibrated pyrometer.

This European Standard specifies traceable calibration methods of black-standard thermometers (BST), white-standard thermometers (WST), black-panel thermometers (BPT) and white-panel thermometers (WPT) for use in natural and artificial weathering:

• method A, a contact method, uses a traceable calibrated resistance standard thermometer;

• method B, a contactless method, uses a traceable calibrated pyrometer.

A basic design of types of the thermometers is described in ENISO4892-1.

NOTE1 Historically method A has been used for weathering applications for many years: Method B has been developed recently. Both methods are qualified for weathering applications. They may provide different calibration results that are not interchangeable.

NOTE2 Annex A gives information on the characteristics of BST/WST and BPT/WPT.
