Depending upon the type of asm anticipated for the test sample, the exposure to the chemical agent could be immersion, wipe, spray, or saturated gauze. Five percent Ammonium Hydroxide showed the greatest change 3.
Variations in the stress-strain response of coupons after immersion in 0. The type of conditioning immersion or wet patch depends upon the end-use of the material. Provisions are made for various exposure times, stress conditions, and exposure to reagents at elevated temperatures.
Test results were compared with the water control of the immersed tests. 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. 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.
If used as a container or transfer line, immerse the specimens. All weight and dimension changes were less than 0.
Send us a request Wilton UK: 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 arbitrary. Standard reagents are specified to establish results on a comparable basis.
Chemical reagents can include lubricants, cleaning agents, inks, foods, or anything else that the test material may be expected to come in contact with. 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.
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. Formally confirming that your products and services meet all trusted external and internal standards. Further testing is required to confirm whether 0. The values given in parentheses are for information only. These practices include provisions for reporting changes in weight, dimensions, appearance, and strength properties.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Link to Active This link will always route to the current Active version of the standard.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. 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. Variations in test coupon depth indicate that these test plates had greater variation in depth across the plate than the other test plates.
This standard and ISO Part 3 address the same subject matter, but differ in technical d54 and the results cannot be directly compared between the two test methods. It should also be noted that two of the coupons 1 lb and c show much higher stress-strain response than a.
The type of conditioning immersion or wet patch depends upon the end-use of the material. Chemical reagent levels in the containers were maintained so that the coupons were fully submerged over the seven-day soaking period.
It was found that two and half rotations produced the desired strain and that the strain level remained constant over a seven-day period. 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. Provisions are made for various exposure times, strain conditions and elevated temperatures.
All chemical reagents appear to decrease the laminates flexural yield stress and yield strain. 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 aatm for resistance to chemical reagents, simulating xstm in potential end use environments.
Possible reasons for the lower response of coupon a are the influence of BOD or a flaw in the test coupon cut from Plate Specific hazards statements are given in Section 7.

The test samples are then sealed in a container, and either left at room temperature or placed in an oven. Possible reasons for the lower response are influence of 0. This slight angle is a characteristic of the JetCut process.
