If the material will only see short exposures or will be used in close proximity and reagent may splash or spill on the material, the wet patch aztm of applying reagent should be used.

Specimens can be weighed and measured prior to contact with the chemical reagent. The influence aatm 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. BOD coupons were taken from Plates 12 d5433 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 test includes provisions for reporting changes in weight, dimensions, appearance and strength properties. After the agreed upon period of time, the specimens are removed and evaluated for desired properties such as change in weight, appearance or tensile properties vs. After the agreed upon period of time, the specimens are removed and evaluated for desired properties such as change in weight, appearance or tensile properties vs.

Standard reagents are specified to establish results on a comparable basis. This standard and ISO Part 3 address the same subject matter, but differ in atsm content and the results cannot be directly compared between the two test methods. Provisions are made for various exposure times, strain conditions and elevated temperatures. 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.

The specification of atsm conditions provides a basis for standardization and serves as a guide to investigators wishing to compare the relative resistance of various dd543 to typical chemical reagents. Posted by Tabitha at 8: Specific hazards statements are given in Section 7.

Provisions are made for various exposure times, stress conditions, and exposure to reagents at elevated temperatures. The strain fixtures and laminate coupons were placed in Plastic containers filled with chemical reagent. Chemical reagent levels in the containers were maintained so that the coupons were fully submerged over the seven-day soaking period.

Evaluating the Resistance of Plastics to Chemical Reagents

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 chemical reagents appear to decrease the laminates flexural yield stress and yield strain.

Chemical reagents can include lubricants, cleaning agents, inks, foods, or anything else that the test material may be expected to come in contact with.
