Ast confirming that your products and services meet all trusted external and internal standards. This standard does not purport to address all of the safety concerns, if any, associated with its use.
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.
This test covers the evaluation of plastic materials for resistance to chemical reagents, simulating performance in potential end use environments. Provisions are made for various exposure astj, stress conditions, and exposure to reagents at elevated temperatures.
Five percent Ammonium Hydroxide showed the greatest change 3. This slight angle resulted in laminate coupons being moderately wider on one face top compared to bottom. It is the responsibility of the user asm 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.
Certification Formally confirming that your products and services meet all trusted external and internal standards. The device uses a three point bending design with coupon contact dimensions similar to those used in the D test.
These practices include provisions for reporting changes in weight, dimensions, appearance, and strength properties.
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.
Further testing is required to confirm the influence of BOD reduction on the coupon flexible yield stress. Whether your business is local or global, we can ensure your products meet quality, health, v543, safety, and social accountability standards for virtually any market around the world.
Need help or have a question? Prior to ASTM D testing specimen coupons were tested in the device using a strain gauge bonded to the bottom of the specimen coupon. All weight and dimension changes were less than 0.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. All chemical reagents appear to decrease the laminates flexural yield stress and yield strain. Send us a request Need help or axtm a question?
For applications involving continuous immersion, the data obtained in short-time tests are of interest only in eliminating the most unsuitable materials or indicating a probable relative order of resistance to chemical reagents. Provisions are made for various exposure times, strain conditions and elevated temperatures. Historical Version s – view previous versions of standard.
Chemical reagents can include lubricants, cleaning agents, inks, foods, or anything else that the test material may be expected to come in contact with. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
ASTM D – 14 Standard Practices for Evaluating the Resistance of Plastics to Chemical Reagents
Variations in the stress-strain response of coupons after immersion in 0. Posted by Tabitha at 8: Specimens can be weighed and measured prior to contact with the chemical reagent.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business d5443. Validating the specifications, value and safety of your raw materials, products and assets. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Work Item s – proposed revisions of this standard. BOD coupons were taken from Plates 12 and Inspection Validating the specifications, value and safety of your raw materials, products and assets. A total of 30 laminate coupons were tested: Specific hazards statements are given in Section 7. Assurance Testing Inspection Certification.
ASTM D Practice for Evaluating the Resistance of Plastics to Chemical Reagents
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. 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. Active view current 5d43 of standard.
If used as a container or transfer line, specimens should be immersed. Possible reasons for the lower response of coupon a are the influence of BOD or a flaw in the test coupon cut from Plate It should also be noted that two of the coupons 1 lb and c show much higher stress-strain response than a. Standard reagents are specified to establish results on a comparable basis.
The values given in parentheses are for information only. The choice of types and concentrations of reagents, duration of immersion or stress, or both, level of stress, temperature of the test, and properties to be reported are necessarily d534. After the agreed upon period of time, the specimens are removed and evaluated for asgm properties such as change in weight, appearance or tensile properties vs.
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. This coupon was discarded and was not used in the study. These practices include provisions for reporting changes in weight, dimensions, appearance, and strength properties. Specific hazards statements are given in Section 7.
