ASTM D5264-98 (R2019) pdf free download.Standard Practice for Abrasion Resistance of Printed Materials by the Sutherland Rub Tester.
1.1 This practice covers a procedure for determining the abrasion resistance of printed materials using the Sutherland Rub Tester, or its equivalent, equipped with full-width rubber pads and using standardized receptors.
1.2 This practice is applicable to labels, folding cartons, corrugated boxes, inserts, circulars, and other packaging materials having applied graphics on a flat substrate.
4. Summary of Practice
4.1 The test specimen is mounted on top of the rubber pad on the Sutherland base and the receptor is cut to lit the 0.91-kg (2-tb) or the 1.81-kg (4-1b) weight (depending on which one is being used). The receptor is mounted to the weight. The test duration is dctcrmincd by the number of strokes (a strokc is one back-and-forth cycle) the sample is rubbed. The number of strokes desired is preset Ofl the Sutherland Timer. The weight is mounted on the Sutherland and the machine is turned on. The Sutherland will shut oil automatically when the desired number of strokes is completed.
4.2 The test specimen is removed from the Sutherland base and examined for degree of print degradation. i’hc receptor is analyzed for the amount of ink transferred from the specimen. Results are compared to an agreed upon standard sample tested in the identical fashion.
5. Significance and Use
5.1 Abrasion resistance is a desirable and sometimes critical property of printed materials. Abrasion damage can occur during shipment, storage, handling, and end use. The result is a significant decrease in product appearance and legibility of product intbrmation. The amount of abrasion damage to a printed substrate is dependent on shipping conditions, possibly temperature and humidity. time, and many other variables. This practice provides a way of comparing abrasion resistance of printed materials under laboratory conditions.
5.2 This practice also can be used to evaluate the relative abrasion resistance of printed inks, coatings, laminates, and substrates.
5.3 This practice can be modified to measure the effects of the product (detergent powder, food, beverages, etc.) Ofl abrasion resistance, as may occur in spillage or leakage in transit.
5.4 This practice can provide a reasonably simple procedure that can be used by both the buyer and the seller of printed materials to determine if the product ollered for sale meets some predetermined standard for abrasion or scull resistance.ASTM D5264 pdf download.
