Washability and Scrubbing Resistance
Washability and Scrub Resistance Tester Model 494 MC-Basic ISO
ERICHSEN 494 MC 型耐洗刷性测试仪（附带水平支脚）有一个顶盖板，上面放置了用于测试性能的钢槽。此外，它还配有两个试样夹紧装置。由微控制器控制的高精度步进电机可实现驱动框架的周期性线性移动，该框架用于夹持/引导磨损体，具有很高的重复性。用于插入研磨体的旋转安装框架最多可固定/引导三个研磨体。因此，最多可进行三次平行磨损试验。若要按照 DIN EN ISO 11998 标准进行测试，则必须安装随附的 ISO 适配器（型号 494 MC-Basic ISO）。
通过键盘和 6 行显示屏操作/控制冲程（启动、停止、复位）非常方便。
目的和应用: 494 MC 型用于评估涂层（尤其是乳化漆和刷墙漆）的耐洗性、耐磨性和清洁性。由于参数可调范围很大很宽，所以该种测试仪还可用于其他个别特殊的试验项目（例如用于检验去污溶液）。
测试原理: 在标准应用中，亚光黑色的PVC箔将被涂上一层，如果需要的话，将以规定的方式弄脏。在夹入设备后，它将暴露在清洗液的影响下，移动擦洗体的压力。
- 测试符合 DIN 53 778- 2 *）（Mod. 494 MC-Basic DIN）
清洗体是一个定型的猪鬃刷，装有 250 克清洗液。污染物是否已被清除或涂层是否已被洗刷至基体，将在商定的洗刷循环次数后进行检查。*) 已撤销，由 DIN EN ISO 11998 取代 - 测试符合 DIN EN ISO 11 998 (Mod. 494 MC-Basic ISO)
擦洗体是一种特定类型的研磨垫，重 135 克，测试前只用特定量的清洗液润湿一次。擦洗应变（200 次双击）后，将测定涂层单位面积的质量损失和平均层厚损失。
