是一个马达驱动的仪器移动打印标本通过一个弧形的加权试纸。The Sutherland Rub Tester has been redesigned to improve its operation.萨瑟兰擦测试仪已被重新设计，以改善其运作。James River's corporate research and development laboratories did extensive testing of the Sutherland Rub Tester.詹姆斯河的企业研究和开发实验室萨瑟兰擦试验机广泛的测试。The result of this work is an affordable abrasion testing instrument that retains all the features that made it an industry standard plus improvements that ensure it will remain the industry standard.这项工作的结果，是一种经济实惠的耐磨测试仪，保留所有的功能，使得它的行业标准，加上改进，以确保它仍将是行业标准。

The stroke of the tester has been shortened which increases the precision and more closely simulates abrasion damage found in the field.测试仪的行程已缩短，从而提高精度和更加紧密地模拟在现场发现的磨损损坏。James River research and other published work in the print abrasion testing arena have shown that quick strokes simulate some types of rub damage (most notably shipping damage).詹姆斯河的研究，并发表在其他打印磨损测试领域的工作已经表明，快速的笔触模拟擦某些类型的损害（最显着的运输损坏）。

A single mounting pad for the test strip is now cut to fit the weight.现在安装一个单一的试纸条的垫以适合的重量。It was found that precision of the test is increased by using a 2 inch (5 cm) by 4 inch (10 cm) pad on the bottom of the weight .结果发现，测试精度是通过使用2英寸（5厘米），4英寸（10厘米），重量底部垫增加。Two pound and four pound weights and scoring fixture are included.包括两磅和4磅重的重量和得分夹具。

A supply of 80 x 80 count bleached muslin cloth (cloth not included) has been found useful in testing wet smear, wet rub, and wet bleed.80 × 80的计数漂白的薄纱布（不包括布）的供应，已发现有用的测试湿涂片，湿擦，湿出血。The Sutherland Rub Tester is designed to evaluate the scuffing or rubbing resistance of the printed or coated surface of paper, paperboard, film, etc. The test results are reproducible.萨瑟兰擦试验机的目的是评估印刷的纸张或涂层表面耐划伤或摩擦，纸板，薄膜等的测试结果重复性。

The following tests may be made with the instrument:下面的测试，可能与仪器：

• Dry Rub干擦
• Wet Rub湿擦
• Wet Bleed or Transfer湿出血或接送

• Wet Smear湿涂片
• Functional Rub功能擦

The test requires two pieces of stock, the printed test specimen and a test receptor, which is usually unprinted.测试需要两件货，打印的测试样品和测试受体，它通常是未打印。Cut a test specimen, approximately six by three inches, representing average ink lay and coverage.剪切试样，约六三英寸，相当于平均油墨裁员和覆盖面。When the printed area permits, the six inch direction should be cut across the grain of the sheet, but must not cross pressed or cut scores.6英寸方向的印刷面积允许时，应切断整个表的粮食，但不得跨按下或削减的分数。

Prepare test strips of unprinted material from the same shipment of stock used in printing the test samples.准备从相同的股票在打印测试样本用于装运未打印材料的试纸。Cleanly cut 2 x 7 inch strips for the four-pound weight are prepared by placing a strip face down against the end pin of the scoring device and scoring the strip at the white dot positions to facilitate bending the strip to conform to the test block.干净切为四磅重的2 × 7英寸带准备放置一个带面，对计分设备结束针得分地带白点的位置，以方便弯曲的地带，以符合试块。

To prepare samples for the two-pound weight, 2 x 5-1/4 inch strips are placed face down against the end pin of the scoring device and score at the red dot position to facilitate bending the strip to conform to the test weight.要准备两磅重的样品，放置2 × 5-1/4英寸带面朝下对计分设备的结束针，在红点的位置，以方便弯曲的地带，以符合重量测试的得分。
