    New Test Method for Contact Transfer and Residual Analysis After Decontamination Experiments

    (What is a Work Item?)

    Developed by Subcommittee: E54.03 | Committee E54 | Contact Staff Manager


    1. Scope

    1.1 This test method will describe the procedures to be used after the performance of a decontamination experiment on a laboratory test panel to insure collection of adequate samples to determine the amount of residual contamination remaining after the end of the experiment. The samples are collected via contact transfer and are analyzed for the amount of residual contaminant remaining after the decontamination experiment.

    After materials are decontaminated, it becomes necessary to monitor the material for any remaining contamination prior to releasing the material for use by unprotected personnel. For chemical warfare agents, the chemical agent detector paper response test indicates whether the contaminant present in or on the test material after the treatment process would result in a colorimetric response (i.e., positive response). M8 and M9 chemical agent detector papers are qualitative, surface-sampling techniques that provide a colorimetric response when the paper comes in contact with liquid chemical agent. A negative chemical agent detector paper response is typically a performance criterion in technology transition agreements and requirement documents. This method of determining that a material has completed decontamination is inadequate since residual contamination, which can leach out of the material over the course of several hours, or days, may remain within the material. This test method allows the amount of contaminant remaining in materials after decontamination to be quantified so the amount of risk present from the residual contaminant can be assessed accurately by qualified personnel. Practitioners performing decontamination experiments in a laboratory would need this test method.
