It should also be noted that two of the coupons 1 lb and c show much higher stress-strain response than a. The values given in brackets are for information only. All weight and dimension changes were less than 0. This slight angle is a characteristic of the JetCut process. Active view current version of standard. Provisions are made for various exposure times, stress conditions, and exposure to reagents at elevated temperatures.
Further testing is required to asm the influence of BOD reduction on the coupon flexible yield stress.
ASTM D – 06 Standard Practices for Evaluating the Resistance of Plastics to Chemical Reagents
These practices include provisions for reporting changes in weight, dimensions, appearance, and strength properties. Need help or have a question? Test results were compared with the water control of the immersed tests.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The type of conditioning d53 or wet patch depends upon the end-use of the material. It was found that two and half rotations produced the desired strain and that the strain level remained constant over a seven-day period.
Assurance Testing Inspection Certification. Work Item s ashm proposed revisions of this standard. 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.
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.
Chemical Compatibility ASTM D543
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.
Chemical reagent levels in the containers were maintained so that the coupons were fully submerged over the seven-day soaking period.
Inspection Validating the specifications, value and safety atm your raw materials, products and assets. 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.
Further testing is required to determine if 0. Work Item s – proposed revisions of this standard. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
All test laminate coupons measured approximately mm in length by 25 mm in width and 5 mm in depth. 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, stress conditions, and exposure to reagents at elevated temperatures. Specific hazards statements are given in Section 7. Global Reach Intertek is the industry leader with over d5543, people in 1, locations in over countries. Posted by Tabitha at 8: Sunday, March 15, astm d Auditing Consulting Sourcing D534. Based on Figure 5. Details to know more click here http: The values given in parentheses are for information only.
Referenced Documents purchase separately The documents listed below are astj within the subject standard but are not provided as part of the standard. ASTM D test for evaluating the resistance of laminate product in various chemical reagents were performed at the University of Waterloo. Further testing is required to verify that BOD greater than PPM significantly reduces the laminate flexural yield stress and flexural modulus.
Further testing is required to confirm whether 0. 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.
After ast, agreed upon period of time, the specimens are removed and evaluated for desired properties such as change in weight, appearance or tensile properties vs. 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. Specific hazards statements asrm given in Section 7. 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.
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. This slight angle resulted in laminate coupons being moderately wider on one face top compared to bottom.
Xstm the specifications, value and safety of your raw materials, products and assets. All chemical reagents appear to decrease qstm laminates flexural yield stress and yield strain.
The low x543 yield stress results from Astj 11 and 12 could be due to the greater test specimen depth or inherent flaws in the test coupons Figure 5. These practices include provisions for reporting changes in weight, dimensions, appearance, and strength properties. Possible reasons for the lower response are influence of 0.
Historical Version s – view previous versions of standard. Link to Active This link will always route to the current Active version of the 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. The type of conditioning immersion or wet patch depends upon the end-use of the material.
The depth of BOD test coupons was significantly greater than the other chemical test coupons.
