ASTM G151-06 - 15.11.2006
 
1. Scope

1.1 This practice provides general procedures to be used when exposing nonmetallic materials in accelerated test devices that use laboratory light sources. Detailed information regarding procedures to be used for specific devices are found in standards describing the particular device being used. For example, detailed information covering exposures in devices that use open flame carbon arc, enclosed carbon arc, xenon arc and fluorescent UV light source are found in Practices G 152, G 153, and G 154, and G 154 respectively.

Note 1—Carbon-arc, xenon arc, and fluorescent UV exposures were also described in Practices 23, G 26, and G 53 which referred to very specific equipment designs. Practices G 152, G 153, and G 154, and G 155 are performance based standards that replace Practices G 23, G 26, and G 53.

1.2 This practice also describes general performance requirements for devices used for exposing nonmetallic materials to laboratory light sources. This information is intended primarily for producers of laboratory accelerated exposure devices.

1.3 This practice provides information on the use and interpretation of data from accelerated exposure tests. Specific information about methods for determining the property of a nonmetallic material before and after exposure are found in standards describing the method used to measure each property. Information regarding the reporting of results from exposure testing of plastic materials is described in Practice D 5870.

Note 2—Guide G 141 provides information for addressing variability in exposure testing of nonmetallic materials. Guide G 169 provides information for application of statistics to exposure test results

Note 3—This standard is technically equivalent to ISO 4892, Part 1.

1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
