产品不同,标准要求也不同,我们公司的产品(低压电器)就要求用酒精擦拭.

图标的质量要求应符合具体产品标准中对铭牌的质量要求,如果该产品没有标准或标准中没有规定图标的质量要求时,以下要求应满足:
手持沾水的棉布擦图标15S和手持沾汽油的棉布擦图标15S,检查图标耐擦的符合性。本试验结束后,图标应仍是清晰可辩的,不能被很容易的揭去。如果使用标签铭牌,不应出现卷边现象。
注:用于耐摩擦试验的精制汽油的脂肪烃类己烷溶剂具有最大芳香烃含量的体积百分比应为0.1%,贝壳松脂丁醇(溶解溶液)值为29,初始沸点应大致为65℃,干涸点69℃左右,单位体积的质量约为0.7kg/L。

我公司是有激光打,应该不用做这项试验吧

抹布也是不一样的哦,
曾经试过,一个很粗糙的抹布和细腻柔软的抹布结果不一样,真不知道怎么判定。

做测试有段时间了,传说中的汽油我没见过,我们都是用酒精代替的,TUV也认同

UL对园林工具铭牌耐久的测试要求:
46 Permanence of Marking Tests
46.1 General
46.1.1 A required marking shall be molded, die-stamped, paint-stenciled, stamped or etched on metal, or indelibly stamped on pressure-sensitive labels secured by adhesive. Pressure-sensitive labels secured by adhesive shall comply with the requirements in 46.1.2 – 46.4.1. Ordinary usage, handling, storage, and the like of the appliance will be considered in determining the permanence of a marking.
46.1.2 After being subjected to the conditioning specified in 46.2.1 – 46.4.1, the adhesion of a pressure-sensitive label or a label secured by cement or adhesive is considered to be acceptable if
immediately following removal from each test medium, and after being exposed for 24 hours to room temperature following removal from each test medium:
a) Each sample demonstrates good adhesion and edges are not curled;
b) The label resists defacement or removal as demonstrated by scraping across the test panel
with a flat metal blade, 1/32 inch (0.8 mm) thick, held at a right angle to the test panel; and
c) The printing is legible and is not defaced by rubbing with thumb or finger pressure.
46.2 Oven aging test
46.2.1 Three samples of the label, applied to test surfaces as in the intended application, are to be conditioned for 240 hours in an air oven maintained at the temperature specified in Table 46.1.
46.3 Immersion test
46.3.1 Six samples of the label, applied to test surfaces as in the intended application, are to be
conditioned for 24 hours in a controlled atmosphere maintained at 23 ±2°C (73 ±4°F) with a 50 ±5 percent relative humidity. Three samples are then immersed in water and three samples are immersed in oil at a temperature of 21 ±2°C (70 ±4°F) for 48 hours in each case.
46.4 Standard atmosphere test
46.4.1 Three samples of the label, applied to test surfaces as in the intended application, are to be conditioned for 72 hours in a controlled atmosphere maintained at 23 ±2°C (73 ±4°F) with a 50 ±5 percent relative humidity.
