ASTM G153-2021 Scope of application
1.1 “This practice covers the basic principles and operating procedures for using enclosed carbon-arc light and water apparatus intended to reproduce the weathering effects that occur when materials are exposed to sunlight (either direct or through window glass) and moisture as rain or dew in actual use. This practice is limited to the procedures for obtaining, measuring, and controlling conditions of exposure. A number of exposure procedures are listed in an appendix; however, this practice does not specify the exposure conditions best suited for the material to be tested.

NOTE 1:”Practice G151 describes performance criteria for all exposure devices that use laboratory light sources. This practice replaces Practice G23, which describes very specific designs for devices used for carbon-arc exposures. The apparatus described in Practice G23 is covered by this practice.

1.2 “” Test specimens are exposed to enclosed carbon arc light under controlled environmental conditions.

1.3 “” Specimen preparation and evaluation of the results are covered in various methods or specifications for specific materials. General guidance is given in Practice G151 and ISO 4892-1. More specific information about methods for determining the change in properties after exposure and reporting these results is described in ISO 4582.

1.4 “” The values stated in SI units are to be regarded as the 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.

1.5.1 “” Should any ozone be generated from the operation of the light source, it shall be carried away from the test specimens and operating personnel by an exhaust system.

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.

1.1 “This code covers the fundamentals and operating procedures for the use of enclosed carbon arc lamps and water equipment designed to reproduce the weathering effects of materials when exposed to sunlight (direct or through window glass) and moisture such as rain or dew in actual use. This protocol is limited to procedures for obtaining, measuring, and controlling exposure conditions. A number of contact procedures are listed in the appendix; However, this procedure does not specify appropriate exposure conditions for the material to be tested.

Note 1: Specification G151 describes performance standards for all exposure devices using laboratory light sources. This specification replaces specification G23, which describes a very specific design of a device for carbon arc exposure. Devices described in regulation G23 are included in this regulation.

1.2 “The sample is exposed to a closed carbon arc under controlled environmental conditions.

1.3 “Sample Preparation and Result Evaluation” is included in various methods or specifications for specific materials. For general guidance see Practice G151 and ISO 4892-1. More specific information is described in ISO 4582 on methods for determining post-exposure property changes and reporting these results.

1.4 “Values expressed in the International System of Units shall be considered standard values.

1.5 “This standard is not intended to address all safety concerns (if any) associated with its use. Users of this standard are responsible for establishing appropriate safety, health and environmental practices prior to use and for determining the applicability of regulatory restrictions.

1.5.1 “If the operation of the light source produces any ozone, it shall be removed from the sample and the operator through the exhaust system.

1.6 “This international standard is based on internationally recognized standardization principles established in the Decision on Principles for the Development of International Standards, Guidelines and Recommendations issued by the WTO Committee on Technical Barriers to Trade (TBT).
