This coupon was discarded and was not used in the study. Provisions are made for various exposure times, strain conditions and elevated temperatures. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Possible reasons for the lower response are influence of 0.
BOD coupons were taken from Plates 12 and 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.
The values given in brackets are for information only. The test includes provisions for reporting changes in weight, dimensions, appearance and strength properties. Posted by Tabitha at 8: 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.
All weight and dimension changes were less than 0.
Chemical Compatibility ASTM D543
This test covers the evaluation of plastic materials for resistance to chemical reagents, simulating performance in potential end use environments.
This standard does not purport to address all of the safety concerns, if any, associated with its use. This slight angle is a characteristic of the JetCut process.
Based on Figure 5. Inspection Validating the specifications, value and safety of your atsm materials, products and assets. Prior to ASTM D testing specimen coupons were tested in the device using a strain gauge bonded to the bottom of the specimen coupon. It should also be noted that two of the coupons 1 lb and c show much higher stress-strain response than a.

ASTM D – 06 Standard Practices for Evaluating the Resistance of Plastics to Chemical Reagents
The strain fixtures and laminate coupons were placed in Plastic containers filled with chemical reagent. At the completion of the seven-day exposure period asm coupon was visually evaluated and mechanically tested in accordance with ASTM D to determine if the stressed chemically exposed laminates mechanical properties changed.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Sunday, March 15, astm d If the material will only see short exposures or will be used in close proximity and reagent may splash or spill on the material, the wet patch method of applying reagent should be used.
Five percent Ammonium Hydroxide showed the greatest change 3.
adtm Chemical reagent levels in the containers were maintained so that the coupons were fully submerged over the seven-day soaking period. Validating the specifications, value and safety of your raw materials, products and assets. If used as a container or transfer line, immerse the specimens. The type of conditioning immersion or wet patch depends upon the end-use of atm material. Note 1 This standard and ISO Part 3 address the same subject matter, but differ in technical content and the results cannot be directly compared between the two test d54.
The type of conditioning immersion or wet patch depends upon the end-use of the material. Standard reagents are specified to establish results on a comparable basis. This standard and ISO Part 3 address the same subject matter, but differ in technical content and the results cannot be directly compared between the two test methods.
Depending upon the type of contact anticipated for the test sample, the exposure to the chemical agent could be immersion, wipe, spray, or saturated gauze. Specific hazards statements are given in Section 7. Link to Active This link will always route to the current X543 version of the standard. For applications involving continuous immersion, the data obtained in short-time tests are of interest only in eliminating the most unsuitable materials asfm indicating a probable relative order of resistance to chemical reagents.
Base the selection of test conditions on the manner and duration of contact with reagents, the temperature of the system, applied stress, and other performance factors involved in the particular application.
The low flexural yield stress results from Plates 11 and 12 x543 be due to the greater test specimen depth or inherent flaws in the test coupons Figure 5. Link to Active This link will always route to the current Active version of the standard.
Variations in the stress-strain response of coupons after immersion in 0.
