This slight angle is a characteristic of the JetCut process. The values given in brackets are for information only.

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

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

Weight and Dimensions Changes, test results indicate that the laminate product 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. Wstm on Figure 5. Specimens are by the agreement of those concerned and can include Tensile bars, disks, flex bars etc.
