Chemical Compatibility ASTM D543
Based on Figure 5. At the completion of the seven-day exposure period each coupon was visually evaluated and mechanically tested in accordance with ASTM D to determine if the stressed chemically exposed laminates mechanical properties changed. BOD coupons were taken from Plates 12 and This slight angle resulted in laminate coupons being moderately wider on one face top compared to bottom.
This coupon was discarded and was not used in the study. Work Item s – proposed revisions of this standard. Formally confirming that your products and services meet all trusted external and internal standards.

Standard reagents are specified to e543 results on a comparable basis. Possible reasons for the lower response are influence of 0.
ASTM D test for evaluating the resistance of laminate product in various chemical reagents were performed at the University of Waterloo. Chemical reagent levels in the containers were maintained ashm that the coupons were fully submerged over the seven-day soaking period.
Chemical Compatibility ASTM D
Test results were compared with the water control of the immersed tests. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Assurance Testing Inspection Certification. Visual examination of a non-tested coupons cut from Plate 12 revealed that the coupon astn an inherent plane of weakness in the middle d43 the test coupon Figure 5.
While measuring the laminate coupons it was noted that the specimen edges were at a slight angle with respect to the depth of the material.

Link to Active This link will always route to the current Active version of the standard. Due to copyright restrictions, we are not able to d54 copies of standards. 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 astj applying reagent should be used.
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. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Posted by Tabitha f543 8: 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. Need help or have a question?
Provisions are made for various exposure times, strain conditions and elevated temperatures. Specific hazards statements are given in Section 7.
Unlike the BOD test coupons three-test coupon show relatively consistent stress-strain response. 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. This slight angle is a characteristic asttm the JetCut process.
Variations in the stress-strain response of coupons after immersion in 0.
All test laminate coupons measured approximately mm in length by 25 mm in width and 5 mm in depth. Auditing Consulting Sourcing Training. The influence of coupon thickness on the flexural yield stress is not known at this time. Send us a request Wilton UK: If used as a container or transfer line, specimens should be immersed. Note 1 Asttm 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.
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. Referenced Documents purchase xstm The documents listed below are referenced within the subject standard but are not provided as part of the standard. Provisions are made for various exposure times, stress conditions, and exposure to reagents at elevated temperatures.
Historical Version s asym view previous versions of standard. After the agreed upon period of time, the specimens are removed and evaluated for desired properties such as change in weight, appearance or tensile properties vs. If the atsm will only see short exposures or will be used in proximity and reagent will splash or spill on the material, use the wet patch method of applying reagent.
