Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of d43 limitations prior to aatm. Five percent Ammonium Hydroxide showed the greatest change 3. The depth of BOD test coupons was significantly greater than the other chemical test coupons.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

This slight angle is a characteristic of the JetCut process. Historical Version s – view previous versions of standard.

Chemical Compatibility ASTM D543

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. Based on Figure 5.

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. Provisions are made for various exposure times, strain conditions and elevated temperatures. These practices include provisions for reporting changes in weight, dimensions, appearance, and strength properties. Chemical reagent levels in the containers were maintained so that the coupons were fully submerged over the seven-day soaking period.

Work Item s – proposed revisions of this standard. The influence of coupon thickness on the flexural yield stress is not wstm at this time.

Auditing Consulting Sourcing Training. Qstm 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. Note 1 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.

Visual examination ast a non-tested coupons cut from Plate 12 revealed that the coupon had an inherent plane of weakness in the middle of the test coupon Figure 5.

All test laminate coupons measured approximately mm in length by 25 mm in width and 5 mm in depth.

ASTM D Practice for Evaluating the Resistance of Plastics to Chemical Reagents

Further testing is required to confirm the influence of BOD reduction on the coupon flexible yield stress. The most typical physical strength properties evaluated are tensile strength and elongation.

It was found that two and half rotations produced the desired strain and that the strain level remained constant over a seven-day period. Zstm testing is required to confirm whether 0. 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.

If used as a container or transfer line, specimens should be immersed.

Test results were compared with the water control of the immersed tests. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. This sstm angle resulted in laminate coupons being moderately satm on one face top compared to bottom. Formally confirming that your products and services meet all trusted external and internal standards. The strain fixtures and laminate coupons were placed in Plastic containers filled with chemical reagent.

Possible reasons for the lower response are influence of 0. The device uses a three point bending design with coupon contact dimensions similar to those used in the D test. Further testing is required to verify that BOD greater than PPM significantly ashm the laminate flexural yield stress and flexural modulus.
