ASTM Subcommittee E20.02 on Radiation Thermometry

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 or infrared (IR) 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.


The E20.02 was started shortly after the E20 Committee was established in 1962.


The following people have served as E20.02 chairman:

  • Henry J. Kostkowski (ca. 1962– ca. 1974)
  • Eugene A. Nutter (ca. 1974 – 1982)
  • G. Raymond Peacock (1982 – 2008)
  • Frank Liebmann (2008–present)


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.[1]

Subcommittee meetings generally take place in May and November as part of the E20 meetings.
