FR Recognition List Number 040 Date of Entry 08/14/2015 
FR Recognition Number 14-463
Standard
ISO ASTM  51608 Second edition 2015-03-15
Practice for dosimetry in an X-ray (bremsstrahlung) facility for radiation processing at energies between 50 KeV and 7.5 MeV
Scope/Abstract
ISO/ASTM 51608:2015 outlines the dosimetric procedures to be followed during installation qualification, operational qualification, performance qualification and routine processing at an X-ray (bremsstrahlung) irradiator. Other procedures related to operational qualification, performance qualification and routine processing that may influence absorbed dose in the product are also discussed.
ISO/ASTM 51608:2015 is one of a set of standards that provides recommendations for properly implementing and utilizing dosimetry in radiation processing. It is intended to be read in conjunction with ISO/ASTM Practice 52628, "Practice for Dosimetry in Radiation Processing".
In contrast to monoenergetic gamma radiation, the X-ray energy spectrum extends from low values (about 35 keV) up to the maximum energy of the electrons incident on the X-ray target.
Extent of Recognition
Complete standard
Rationale for Recognition
This standard is relevant to medical devices and is recognized on its scientific and technical merit and/or because it supports existing regulatory policies.
