5.1 This test method is intended to provide a standardized test procedure of protective materials to ensure comparable results among manufacturers and users.

5.2 This test method involves measurement of the attenuation of X-rays by protective clothing material at an accelerating potential (kVp) between 60 and 130 kVp. These energies are considered to be representative of those commonly used during medical diagnosis.

5.3 The reporting of the attenuation at a specific X-ray energy is intended to allow the end user organization to assess the attenuating properties of the protective clothing material at that energy level.

1.1 This test method establishes procedures for measuring the attenuation of X-rays by protective materials at accelerating potentials from 60 to 130 kVp.

1.2 This test method provides attenuation values of primary beam X-radiation.

1.3 This test method applies to both leaded and non-leaded radiation protective clothing materials.

1.4 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 appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
