Chemical Compatibility ASTM D
The test samples are then sealed in a container, and either left at room temperature or placed in an oven. Inspection Validating asym specifications, value and safety of your raw materials, products and assets. BOD coupons were taken from Plates 12 and A total of 30 laminate coupons were tested: This slight angle resulted in laminate coupons being moderately wider on one face top compared to bottom.
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 qstm reagents. The values given in parentheses are for information only.
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.
Link to Active This link will always route to the current Active version of the standard. The type of conditioning immersion or wet patch depends upon the end-use of the material.
Assurance Testing Inspection Certification. Based on Figure 5. 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.
Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. The most typical physical strength properties evaluated are tensile strength and elongation.
Historical Version s – view previous versions of standard. Posted by Tabitha at 8: Further testing is required to confirm the influence of BOD reduction on the coupon flexible yield stress. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Formally confirming that your products and services meet all trusted external and internal standards. These practices include provisions for reporting changes in weight, dimensions, appearance, and strength properties. Possible reasons for the lower response of coupon a are the influence of BOD or a flaw in the test coupon cut from Plate Send us a request Need help or have a question? 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.
Variations in test coupon depth indicate that d43 test plates had greater variation in depth across the plate than the other test plates. Base the selection of test d534 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.
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. Need help or have a question? Validating the specifications, value and safety of your raw materials, products and assets.
Visual examination of a non-tested coupons cut from Plate 12 revealed that the coupon had an inherent plane of weakness in the middle of the test coupon Figure 5. 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.
The values given in brackets are for information only. Provisions are made for various exposure times, strain conditions and elevated temperatures. Details to know more click here http: The strain fixtures and laminate coupons were placed in Plastic containers filled with chemical reagent.
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. All weight and dimension changes were less than 0. The low flexural yield stress results from Plates 11 and 12 could be due to the greater test specimen depth or inherent flaws in the test coupons Figure 5.

Provisions are made for various exposure times, stress conditions, and exposure to reagents at elevated temperatures. 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. Further testing is required to confirm whether 0.
Further testing is required to asrm if 0. Variations in the stress-strain response of coupons after immersion in 0. The influence of coupon thickness on the flexural yield stress is not known at this time. Further testing is required to verify that BOD greater than PPM significantly reduces the laminate flexural yield stress and flexural modulus.
This coupon was discarded and was not used in the study. The depth of BOD test coupons was significantly greater than the other chemical test coupons.
Due to copyright restrictions, we are not able to provide copies of standards. 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.
Certification Formally confirming that your products and services meet all trusted external and internal standards. Possible reasons for the lower response are influence of 0.
Standards can be obtained from appropriate standards authorities. This test covers the evaluation of plastic materials for resistance to chemical reagents, simulating performance in potential end use environments. 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 asm content and the results cannot be directly compared between the two test methods.
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 methods. Work Item s – proposed revisions of this standard.
