Link to Active This link will always route adtm 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.
Possible reasons for the lower response of coupon a are the influence of BOD or a flaw in the test coupon cut from Plate Further testing is required to confirm the influence of BOD reduction on the coupon flexible yield stress. A total of 30 laminate coupons were tested: The device uses a three point bending design satm coupon contact dimensions similar to those used in the D test.
All test laminate coupons measured approximately mm in length by 25 mm in width and 5 mm in depth. Inspection Validating the specifications, value and safety of your raw materials, products and assets.

The influence of coupon thickness on the flexural yield stress is not known at this time. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
If used as a container or transfer line, specimens should be immersed. The type of conditioning immersion or wet patch depends upon the end-use of the material. Standard reagents are specified to establish results on a comparable basis. Posted by Tabitha at 8: Unlike the BOD test coupons three-test coupon show relatively consistent stress-strain response.
Chemical Compatibility ASTM D543
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. Weight and Dimensions Changes, test results indicate that the laminate product had s543 significant visible appearance changes after exposure to the chemicals reagent and that weight and depth changes are greater than width and length changes.
