Standard Guide for Selection of Substitute, Non-hazardous, Liquid Filling Substances for Packagings Subjected to the United Nations Performance Tests

Importancia y uso:

5.1 Regulations prescribing the test procedures for hazardous materials packaging allow for the substitution of non-hazardous fill materials for packaging performance tests with certain limitations as outlined in 49 CFR 178.602(c). This regulatory guidance has proven to be flexible enough, in common industry practice, to produce variations in the selection of fill materials for package performance tests that may cause inconsistent and non-repeatable test results. This variation has the potential to create significant problems in product liability, packaging selection, and regulatory enforcement in this highly regulated industry. Use of this guide should enhance uniformity in test procedures.

5.2 Consistent and repeatable test results coupled with clear test fill product descriptions will enhance transportation safety by simplifying packaging selection. This will also increase the general level of confidence that package testing, manufacture and use are being guided by sound, generally accepted engineering principles. It also aids in clarifying expectations between the packaging industry and the regulatory authorities.

5.3 The guide will be used by packaging manufacturers, and packaging test labs to create packaging test plans that meet customer needs and conform to the HMR under the widest possible situational circumstances. In addition, for the user of a packaging, certain information about the type and physical characteristics of the material used to test the packaging must be available in the test report and/or notification instruction to allow them to evaluate whether a particular packaging was tested with a substitute material appropriate for the hazardous material to be shipped.

5.4 For more information on the UN certification tests, refer to Guide D4919. For guidance on determining the appropriate fill materials for preparing samples for UN certification testing with solids reference Guide D8135. For conditioning of plastic packaging designs reference Guide D7790.
