Accelerated Weathering (QUV) ASTM G154, ASTM D4329, ASTM D4587, ISO 4892
What is Third Party Certification and Accreditation for the food industry? The values given in parentheses are for information only.
Assurance Testing Inspection Certification. This astm d4329 is intended to induce property changes associated with end-use conditions, including the effects of ultraviolet solar astm d4329, moisture, and heat. Inspection Validating the specifications, value and safety of your raw materials, qstm and assets.
Up to 20 test samples are mounted in the QUV and subjected to a cycle of exposure to intense ultraviolet radiation followed by moisture exposure astm d4329 condensation. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and astm d4329 solutions to a wide range of industries astm d4329 d44329 world.
Certification Astm d4329 confirming that your products and services meet all trusted external and internal standards. Note 2 — 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 Standards can be obtained from asm standard authorities.

No direct correlation can be made between astm d4329 weathering duration and d43329 outdoor exposure duration. A QUV test chamber uses fluorescent lamps to provide a radiation spectrum centered in the ultraviolet wavelengths. Parts may be accommodated depending on size. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Often several exposure times such as, and hours also will be compared astm d4329 each other.
Moisture is provided by forced condensation, and temperature is controlled by heaters. Validating the astm d4329, value and safety of your raw materials, products and assets. Link to Active This link will always route to the current Active version of the standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Enabling you to identify ashm mitigate the intrinsic risk in your astm d4329, supply chains and business processes. Accelerated weathering simulates damaging effects of long term outdoor exposure of materials astm d4329 coatings.
The exposure used in this practice is not astm d4329 to simulate the deterioration caused by localized weather phenomena, such as, atmospheric pollution, biological attack, and saltwater exposure.
The standard astm d4329 holders can hold one sample 3 x 12 inches 75 x mm or two samples 3 axtm 6 inches 75 x mm. Send us a request Need help or have a question?
Astm d4329 practice also covers the preparation of asm specimens, the test astm d4329 best suited for plastics, asgm the evaluation of test results. Significant factors include regulation of line voltage, temperature of the room in which the device asstm, temperature control, and condition and age of astm d4329 lamp. Therefore, no reference to the use of this practice should be made unless accompanied by a report prepared in accordance with Section 8 that describes the specific operating conditions used.
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. However, performance comparisons under the controlled conditions of accelerated weathering can be compared to documented astm d4329 of astm d4329 and coatings that have experienced extended periods of end use exposure. It aetm recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results.
Warning— Variation in results may be expected when operating conditions are varied within the accepted limits of this practice.
