D Temperature is at equilibrium for either an uninsulated or insulated black panel, although the response of the insulated black panel might be slower than that for the uninsulated black panel.

Expose replicates of the test specimen and the control specimen so that statistically signi? What is the test? Table 1 describes commonly used test conditions. Certification Formally confirming that your products and services meet all trusted external and internal standards. dd4587

ASTM D4587

Nondestructive methods are preferred because panels so measured need not be repaired. Do not use this covered area of the specimen as part of the test area. 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.

The ability of a paint or coating to resist deterioration of its physical and optical properties caused by exposure to light, heat, and water can be very significant for many applications.

Water resistance of th Therefore, no reference to the use of this practice shall be made unless accompanied by a report prepared according to Section 10 that describes the specific operating conditions used. The measurement data used to establish these set points was inaccurate, due to an error ast calibration on the part of one manufacturer. Table 1 describes commonly used test conditions. The acceleration factor is material dependent and is only valid if it is based on data from a sufficient awtm of separate exterior and laboratory accelerated exposures so that results used to relate times to failure in each exposure can be analyzed using statistical methods.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. The GRP laminate should not display any deterioration like chalking, flaking, wrinkling, blistering or cracking.

This method is preferred over evaluating materials after an arbitrary exposure time or radiant exposure. Practice G 53 has been withdrawn and replaced by Practice Gwhich describes performance criteria for all exposure devices that use laboratory light sources, and by Practice Gwhich gives requirements for exposing nonmetallic materials in? Your comments will receive careful consideration at a meeting of aastm responsible technical committee, which you may attend.

Often several exposure times such as, and hours also will be compared to each other. D Temperature is at equilibrium for either an uninsulated or insulated aetm panel, although the response of the insulated black panel might be slower than that for the uninsulated black panel.


Auditing Consulting Sourcing Training. Note Previous versions of this practice referenced fluorescent UV devices described by Practice Wstm 53, which described very specific equipment aztm. Additional intervals and periods of condensation may be substituted upon agreement among the concerned parties.

Our glass reinforced polyester laminate, which is the primary material across our product range is constructed with a protective layer of gelcoat having a high thickness of – microns. Refer to Practice G for more information about the construction and differences between uninsulated and insulated black panels. The standard sample holders can hold one sample 3 x 12 inches 75 x mm or two samples 3 x 6 inches 75 x mm.

E Typical uses do not imply that results from exposures of these materials according to the cycle described will correlate to those from actual use conditions. B The d45887 set point given is typical for devices operated without irradiance control. Typically, flat plaques or disks are used for accelerated weathering studies.

NOTE 3—Additional information on sources of variability and on strategies for addressing variability in the design, execution and data analysis of laboratory accelerated exposure tests is found in Guide G Measurements visual or instrumental should be made within a standardized time period or as agreed upon between interested parties.
