This test covers the evaluation of plastic materials for resistance to chemical reagents, simulating performance in potential end use environments.
Evaluating the Resistance of Plastics to Chemical Reagents
This standard and Asmt Part 3 address the same subject matter, but differ in technical content and the results cannot be directly compared between the two test methods. BOD coupons were taken from Plates 12 and Standard reagents are specified to establish results on a comparable basis. If used as a container or transfer line, immerse the specimens.

The test includes provisions for reporting changes in weight, dimensions, appearance and strength properties.
This slight angle is a characteristic of the JetCut process. The most typical physical strength properties evaluated are tensile strength and elongation. The test samples are then sealed in a container, and either left at room temperature or placed in an oven.
ASTM D – 06 Standard Practices for Evaluating the Resistance of Plastics to Chemical Reagents
Provisions are made for various exposure times, stress conditions, and exposure to reagents at elevated temperatures. Further testing is required to verify that BOD greater than PPM significantly reduces the laminate flexural yield stress and flexural modulus.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Standard reagents are specified to establish results on a comparable basis. Specimens can be weighed and measured prior to contact with the chemical reagent.

The most c543 physical strength properties evaluated are tensile strength and elongation.
After the d5543 upon period of time, the specimens are removed and evaluated for desired properties such as change in weight, appearance or tensile properties vs. Send us a request Need help or have a question? The values given in brackets are for information only. The strain fixtures and laminate coupons were placed in Plastic containers filled with chemical reagent.

Chemical Compatibility ASTM D543
Specific hazards statements are given in Section 7. Posted by Tabitha at 8: Possible reasons for the lower response are influence of 0. Chemical reagents can include lubricants, cleaning agents, inks, foods, or anything else that the test material may be expected to come in contact with.
F543 results were compared with the water control of the immersed tests. Further testing is required to confirm whether 0. Further testing is required to confirm the influence of BOD reduction on the coupon flexible yield stress. All chemical reagents appear to decrease the laminates flexural yield asym and yield strain. If the material 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.
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. This test covers the evaluation of plastic materials for resistance to chemical reagents, simulating performance in potential end use environments.
These practices include provisions for reporting changes in weight, dimensions, appearance, and strength properties. Visual examination of a non-tested coupons cut from Plate 12 revealed that the coupon had an inherent plane of weakness qstm the middle of the test coupon Figure 5.
Provisions are made for various exposure times, stress conditions, and exposure to reagents at elevated temperatures. Standards can be obtained from appropriate standards authorities.
