Scope

1.1 This practice covers the exposureof plastics to a specific test environment. The test environment is a laboratory-scale reactor that simulates a landfill withenhanced biological activity. Biological activity is enhanced by adding moisture, recirculating leachate, and heating to 35°C. Plastic exposureoccurs in the presenceof a mediaundergoing anaerobic degradation. The standard media used inthe practice simulates a municipal solid-waste stream. The practice allows for the use of other media to represent particular waste streams. This practice provides exposed specimens for further testing and for comparison with controls. This test environment does not necessarily reproduce conditions thatcould occur in a particular landfill. 1.2 Changes in the material properties of the plastic and controls should be determined using appropriate ASTM test procedures. Changes could encompass physical and chemical changes such asdisintegration and degradation. 1.3 This practice may be used for different purposes. The interested parties therefore must select the following:exposure conditions from those allowed by this practice; criteria for a valid exposure, that is, minimum or maximumchange requirements for the simulated landfill environmentand controls; and magnitudes of material properties changes required for the plastic specimens. 1.4 The values stated in SI units areto be regarded as the standard. The values given in parentheses are for information only. 1.5 This standard does not purport to address all o f the safetyconcerns, if any, associated with its use. It is the responsibilityofthe mer ofthis standard to establish appropriate safety and health practices and determine theapplicability o f regulatory limitations priorto use. Specifichazards statements aregiven in Section 8. NOTE1-There is no similar or equivalent IS0 standard.
