ASTM E3190-19

1.1This practice is intended to provide a basis for simulating radioactive contamination consistent with processes used to evaluate decontamination. The methods described provide a “fixed-type” radiological or surrogate contamination on porous surfaces; these methods provide a surface contamination that is not easily removed by brushing or flushing with water.

1.2The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

1.3This practice is intended to be practiced primarily on porous surfaces such as concrete, marble, granite, grout, brick, tile, asphalt, vinyl floor tile, latex painted gypsum wall board and polyurethane coated wood. Preparation of non-porous substrates is not addressed, although similar methodology may be used.

1.4The chemical simulants shall not include nor generate toxic by-products as defined by U.S. Occupational Safety and Health Administration (OSHA) during preparation, application, or removal under normal conditions. A Safety Data Sheet shall be provided so that appropriate PPE can be selected.

1.5This 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.

1.6This 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.
