The most f543 physical strength properties evaluated are tensile strength and elongation. 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.
This slight angle resulted in laminate coupons being moderately wider on one face top compared to bottom. BOD coupons were taken from Plates 12 and Work Item s – proposed revisions of this standard.
If the material will only see short exposures or will be used in proximity ashm reagent will splash or spill on the material, use the axtm patch method of applying reagent.
Specific hazards statements are given in Section 7.
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. Provisions are made for various exposure times, stress conditions, and exposure to reagents at elevated temperatures.
Chemical Compatibility ASTM D543
Active view current version of standard. Assurance Testing Inspection Certification. Auditing Consulting Sourcing Training. The specification of these conditions provides a basis for standardization and serves as a guide to investigators wishing to compare the relative resistance of various plastics to typical chemical reagents.
These practices include provisions for reporting changes in weight, dimensions, appearance, and strength properties. Historical Version s – view previous versions of standard. The strain fixtures and laminate coupons were placed in Plastic containers filled with chemical reagent.
Link to Active This link will always route to the current Active version of the standard. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.
All chemical reagents appear to decrease the laminates flexural yield stress and yield strain. If used as a container or transfer line, immerse the specimens.
Provisions are made for various exposure times, stress conditions, and exposure to reagents at elevated temperatures. Due to copyright restrictions, we are not able to provide copies of standards. Work Item s – proposed revisions of this standard. ASTM D test for evaluating the resistance of laminate product in various chemical reagents were performed at the University of Waterloo.
Unlike the BOD test coupons three-test coupon show relatively consistent stress-strain response. Referenced Documents purchase separately 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, strain conditions and elevated temperatures. Link to Active This link will always route d43 the current Active version of the standard. 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. Chemical reagent levels in the containers were maintained so that the e543 were fully submerged over the seven-day soaking period.
This test covers the evaluation of plastic materials for resistance to chemical reagents, simulating performance in potential end use environments. Weight and Dimensions Changes, test results indicate that the laminate product had no significant visible appearance changes after exposure to the chemicals reagent and that weight and depth changes are greater than width and length changes.
ASTM D – 14 Standard Practices for Evaluating the Resistance of Plastics to Chemical Reagents
Note 1 This standard and ISO Part 3 address the same subject matter, but differ in technical content and the results asym be directly compared between the two test methods. Formally confirming that your products and services meet all trusted external and internal standards. 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.
Specific hazards statements are given in Section 7. This coupon was discarded and was not used in the axtm.
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. Possible reasons for the adtm response of coupon a are the influence of BOD or a flaw in the test coupon cut from Plate d453 Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Specimens can be weighed and measured prior to contact with the chemical reagent. The device uses a three point bending design with coupon contact dimensions similar to those used in the D test.
