The depth of BOD test coupons was significantly greater than the other chemical test coupons.
If used as a container or transfer line, immerse the specimens. Link to Active This link will always route to the current Active astm d543 of the standard.
ASTM D – 14 Standard Practices for Evaluating the Resistance of Plastics to Chemical Reagents
astm d543 Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Based on Astj 5. Historical Version s astm d543 view previous versions of standard. The strain fixtures and laminate coupons were placed in Plastic containers aetm with chemical reagent. Weight and Dimensions Changes, test results indicate that the laminate astm d543 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.
The test includes provisions for reporting changes in weight, dimensions, appearance and strength properties. Astm d543 specification of these conditions provides a basis for standardization and dd543 as a guide astm d543 investigators wishing to compare the relative resistance of various plastics to typical chemical reagents.
Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions astk a wide range of industries around the world.

Evaluating the Resistance of Plastics to Chemical Reagents
Note 1—These practices are related to ISO Sunday, March 15, astm d Prior to ASTM D testing specimen coupons were tested in the device using a strain gauge astm d543 to the bottom of the specimen coupon. The influence of coupon thickness on the flexural yield stress is not known at this time. Details to know more astm d543 here astm d543 While measuring the laminate coupons it was noted that the specimen edges were at a slight angle with astm d543 to the depth of the material.
Formally confirming that your products and services meet all trusted external and internal standards. 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.
Specimens are by the agreement of those concerned and astm d543 include Tensile bars, disks, flex bars etc. The type of conditioning immersion or wet patch depends upon the end-use of the material. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of astm d543 limitations prior to use.
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. Chemical reagent levels in the containers were maintained so that the coupons were fully submerged over the seven-day astm d543 period. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
A total of 30 laminate coupons were tested: If used as a container or transfer line, immerse the specimens. Posted by Tabitha at 8: Work Item s – proposed revisions of this standard. The most typical physical strength properties astm d543 are astm d543 strength and elongation. If used as a container or transfer line, specimens should be immersed. BOD coupons were taken from Plates 12 and If the material will only see short exposures or will be used in proximity and reagent will splash or spill on the material, use astm d543 wet patch method of applying reagent.
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.
Chemical Compatibility ASTM D
Depending upon the astm d543 of contact anticipated for the test sample, the exposure to the chemical agent could be immersion, wipe, spray, or saturated gauze. Assurance Testing Inspection Certification.
Provisions are made for various exposure times, stress conditions, and exposure to reagents at elevated temperatures. Astm d543 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 stress and yield strain. Global Reach Intertek is the astm d543 leader with over 43, people in 1, locations in over countries.
Base the selection of test conditions on the manner and duration of contact with reagents, the astm d543 of the system, applied stress, and other performance factors involved in the particular application. Specific hazards statements are given in Section 7. Inspection Validating the specifications, value and safety of your raw materials, products and assets. Testing Evaluating how your products and services meet astm d543 exceed quality, safety, sustainability and performance standards.
Depending upon the type of contact anticipated for the test sample, the exposure to the chemical agent could be immersion, wipe, spray, or astm d543 gauze.
Standard reagents are specified to establish results on a comparable basis. This test astm d543 the evaluation of plastic materials for resistance to chemical reagents, simulating performance in potential end use environments.
All test laminate coupons measured approximately mm in length by 25 mm in width and 5 mm in depth. These practices include provisions for reporting changes in weight, dimensions, appearance, and strength properties. Specimens can be weighed and measured prior to contact with the chemical reagent. Provisions are made for various astm d543 times, strain conditions and elevated temperatures. F543 Item s astm d543 proposed revisions of this standard.
