1.1 This practice covers dosimetric procedures to be fol-
lowed in installation quali?cation, operational quali?cation and
performance quali?cation (IQ, OQ, PQ), and routine process-
ing at electron beam facilities to ensure that the product has
been treated with an acceptable range of absorbed doses. Other
procedures related to IQ, OQ, PQ, and routine product pro-
cessing that may in?uence absorbed dose in the product are
also discussed.
1.2 The electron beam energy range covered in this practice
is between 80 and 300 keV, generally referred to as low energy.
1.3 Dosimetry is only one component of a total quality
assurance program for an irradiation facility. Other measures
may be required for speci?c applications such as medical
device sterilization and food preservation.
1.4 Other speci?c ISO and ASTM standards exist for the
irradiation of food and the radiation sterilization of health care
products. For the radiation sterilization of health care products,
see ISO 11137-1. In those areas covered by ISO 11137-1, that
standard takes precedence. For food irradiation, see ISO
14470. Information about effective or regulatory dose limits for
food products is not within the scope of this practice (see
ASTM F1355 and F1356).
1.5 This document is one of a set of standards that provides
recommendations for properly implementing dosimetry in
radiation processing, and describes a means of achieving
compliance with the requirements of ISO/ASTM 52628.Itis
intended to be read in conjunction with ISO/ASTM 52628.
1.6 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appro-
priate safety, health, and environmental practices and deter-
mine the applicability of regulatory limitations prior to use.

dance with internationally recognized principles on standard-
ization established in the Decision on Principles for the

Processing and is the direct responsibility of Subcommittee E61.03 on Dosimetry
Application, and is also under the jurisdiction of ISO/TC 85/WG 3.
