ASTM Subcommittee E20.02 on Radiation Thermometry is a subcommittee of the
ASTM Committee E20 on Temperature Measurement, a committee of
ASTM International. The subcommittee is responsible for standards relating to
radiation
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes:
* ''electromagnetic radiation'', such as radio waves, microwaves, infrared, visi ...
or
infrared
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around ...

temperature measurement. E20.02's standards are published along with the rest of the E20's standards in the ''Annual Book of ASTM Standards'', Volume 14.03.
History
The E20.02 was started shortly after the E20 Committee was established in 1962.
Membership
Membership in the organization is open to anyone with an interest in its activities. Participating members join this subcommittee to write standards and to forward their own interests.
Subcommittee meetings generally take place in May and November as part of the E20 meetings.
