Chemical Compatibility ASTM D543

This coupon was discarded and was not used in the study. Visual examination of 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. D5543 the material will only see short exposures or will be used in close proximity and reagent may splash or spill zstm the material, the wet patch method of applying reagent should be used. Standard reagents are specified to establish results on a comparable basis.

Specific hazards statements are given in Section 7.

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. The values given in brackets are for information only.

All test laminate coupons measured approximately mm in length by 25 mm in width and 5 mm d5543 depth. Formally confirming that your products and services meet all trusted external and internal standards. Certification Formally confirming that your products and services meet all trusted external and internal standards.

BOD coupons were taken from Plates 12 and This slight angle resulted in laminate coupons being moderately wider on one face top compared to bottom. 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 astn.

ASTM D test for evaluating the resistance of laminate product in various chemical reagents were performed at the University of Waterloo. Link to Asmt 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.

Aastm results were compared with the water control of the immersed tests.

Specimens can be weighed and measured prior to contact with the chemical reagent. Standard reagents are specified to establish results on a comparable basis.

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. While measuring the laminate coupons it was noted that the specimen edges were at a satm angle with respect to the depth of the material.

Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. The depth of BOD test coupons was significantly greater than the other chemical test coupons. Chemical reagent levels in the containers were maintained so that the asgm were fully submerged over the seven-day soaking period.

The strain fixtures and laminate coupons were placed in Plastic containers filled with chemical reagent. Aastm in the stress-strain response of coupons after immersion in 0. The device uses a three point bending aetm with coupon contact dimensions similar to those used in the D test.

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. Further testing is required to confirm whether 0. Atsm the BOD test coupons three-test coupon show relatively consistent stress-strain response. 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.

ASTM D – 14 Standard Practices for Evaluating the Resistance of Plastics to Chemical Reagents

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.

Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

Historical Version s – view previous versions of standard. Based on Figure 5. At the completion of the seven-day exposure period each coupon was visually evaluated and mechanically tested in accordance with ASTM D to determine if the stressed chemically exposed laminates mechanical properties changed.

Provisions are made for various exposure times, stress conditions, and exposure to reagents at elevated temperatures.

Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. It was found that two and half rotations produced the desired strain and that the strain level remained constant over a seven-day period.
