Periods of Exposure and Evaluation of Results 9.
Note 1—Previous versions of this practice referenced fluorescent UV devices described by Practicewhich described very specific equipment designs. This practice also covers the preparation of test specimens, and the evaluation of test results.
The GRP laminate should not display any deterioration like chalking, flaking, wrinkling, blistering or cracking. NOTE 11—Fischer illustrates use of rank comparison between test and control materials in speci? 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. If in doubt, users should consult the manufacturer of their device for clarification.
Attach porous specimens to a solid backing such as aluminum that can act as a vapor barrier. A The cycles described are not listed in any order indicating importance, and are not necessarily recommended for the applications listed.
Last previous edition approved in as D — Often several exposure times such as, and hours also will be compared to each other. G Historical convention has established this as a very commonly used test cycle.
Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Significant factors include regulation of line voltage, temperature of the room in which the device operates, temperature control, and condition and age of the lamps.
Our laminate is type tested at the renowned international testing laboratory Exova to certify our products to be weather resistant. Refer to Practice G for detailed information on the caveats applicable to use of results obtained according to this practice. However, for users of equipment made by another manufacturer, the irradiance control system did not have the measurement inaccuracies described above, so running at the new set points will represent a change in the actual irradiance of the test.
This cycle may not adequately simulate the effects of outdoor exposure.
Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world. Turn the device off before removing panels for inspection. The previous set points were 0. Formally confirming that your products and services meet all trusted external and internal standards.
ASTM International is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. Work Item s – proposed revisions of this standard.

NOTE 13—In some cases, exposures are conducted by a contracting agency but property tests are conducted by the contracting party. 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. This practice is intended to induce property changes associated with end-use conditions, including the effects of sunlight, moisture, and heat.
The standardized time period needs to consider conditioning prior to testing. Work Item s – proposed revisions of this standard. The values given in parentheses are for information only. 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.
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 The previous set points were 0. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. C Previous editions of Practice D contained non-mandatory irradiance set points in Table 1 that were commonly used in the industry.
Additional exposure cycles are described in Practice G This practice also covers the preparation of test specimens, and the evaluation of test results. Validating the specifications, value and safety of your raw materials, products and assets. Where is it tested? 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.
NOTE 9—An example of a statistical analysis using multiple laboratory and exterior exposures to calculate an acceleration factor is described by J.

Current edition approved July 1, ASTM D classification defines the standard practice for fluorescent UV and condensation exposures of paint and related coatings. Assurance Testing Inspection Certification.
Adherence to the standard is mandatory across the GCC region and globally. It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results.
All references to exposures in accordance with this practice must include a complete description of the test cycle used. All concerned parties must agree on the speci? Active view current version of standard. 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?
Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. This cycle may not adequately simulate the effects of outdoor exposure. Nondestructive instrumental measurements are recommended whenever possible. Moisture is provided by forced condensation, and temperature is controlled by heaters.
Standards can be obtained from appropriate standard authorities. These cycles would be continued for extended periods of time – up to thousands of hours – simulating even longer periods of time in the real world. Industrial maintenance coatings G.
