It is intended to be used in conjunction with a practice or method that defines specific exposure conditions for an application along with a means to evaluate changes in material properties. This practice is 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 usage. ASTM G ASTM G is a standard that is used as the basis for all other accelerated weathering standards that use fluorescent UV light sources to simulate exposure to natural sunlight. Many standards call up this practice. For a list of these by product category, please see the QUV standards list. Proposal: ASTM WK • Perform UV condiIoning tests according to method and apparatus described in ASTM G‐ Standard PracIce for OperaIng Fluorescent Ultraviolet (UV) Lamp Apparatus for Exposure of Nonmetallic Materials.

Name of Legally Binding Document: ASTM G Standard Practice for Exposing Nonmetallic Materials in Accelerated Test Devices that Use Laboratory Light Sources Name of Standards Organization: American Society for Testing and Materials LEGALLY BINDING DOCUMENT. ASTM G is one of the most commonly used accelerated weathering tests. Various industries use the standard throughout their products' design and development to determine the impact of UV exposure on a non-metallic material. While it is similar to the ASTM G, the apparatus used to mimic the effects of weathering differs. Downloads: Price: Free* [ *Free Regsitration Required] Uploader: Arashigul. It is the responsibility of the astm g of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Specimen preparation and evaluation of the results are covered in ASTM methods or specifications for specific materials. General guidance is given in Practice G and ISO Note 4: General information about methods for determining the change in properties after exposure and reporting these results is described in ISO and.
