ASTM E3283-21

Standard Practice for Preparation of Loose Radiological/Surrogate Contamination on Nonporous Test Coupon Surfaces for Evaluation of Decontamination Techniques

SIGNIFICANCE AND USE
5.1 This practice provides a protocol to compare different decontamination technologies with a standard contamination mechanism and analysis of subsequent decontamination factors/efficiencies.  
5.2 The use of this practice provides for the preparation of test coupons with a known amount of loose radiological or surrogate contaminant on the surface.  
5.3 A standard test coupon is described and a list of potential equipment, contaminants, and contaminating solutions is provided within the procedure.  
5.4 This practice describes a contamination simulation process that meets the requirements of testing performed (previously) by the U.S. Department of Energy and U.S. Environmental Protection Agency for the removal of loose contamination.
SCOPE
1.1 This practice is intended to provide a basis for simulating radioactive contamination consistent with processes used to evaluate decontamination. The methods described provide a “loose-type” radiological or surrogate contamination on nonporous surfaces; these methods provide a surface contamination that may be easily removed by brushing or flushing with water.  
1.2 This practice is intended for nonporous surfaces such as stainless steel, aluminum, glass, laminates, and epoxy painted surfaces. Preparation of porous substrates is not addressed, although similar methodologies may be used. A different practice is employed using Practice E3190, to produce “fixed” contamination.  
1.3 The chemical simulants shall not include nor generate toxic byproducts as defined by U.S. Occupational Safety and Health Administration (OSHA) during preparation, application, or removal under normal conditions. A Safety Data Sheet (SDS) shall be provided so that appropriate personal protective equipment (PPE) can be selected.  
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.5 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.  
1.6 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.
