看得一头雾水
有没有上下文阿
或者w注释之类的

Spot-test:
点测试
negative=absence of CrVI coating,positive=presence of CrVI coating
阴性代表涂层中未证明存在Cr6+,阳性代表涂层中存在Cr6+
(the tested sample should be further verified by boiling-water-extraction method if the spot test result cannot be confirmed)
如果点测试结果阴性,被测样品应该进一步用沸水萃取法检验。
boiling-water-extraction:
沸水萃取法:
negative=absence of CrVI coating
阴性代表涂层中无Cr6+
positive=presence of CrVI coating;
阳性代表涂层中存在Cr6+
the detected concentration in boiling-water-extraction
solution is equal or greater than 0.02 mg/kg with 50cm2 sample surface areas
沸水萃取法中的检测浓度为50cm2样品表面大于等于0.02mg/kg。
以上
其实是对照铬离子测试方法的中文版翻译的^_^

现场观察检验:
阴性=不存在六价铬镀层;阳性=存在六价格镀层??
(如果现场观察检验不能确认的话,需要用沸水提取方法确认测试样品)
沸水提取方法:
阴性=不存在六价铬镀层;
阳性=存在六价格镀层;沸水提取法测定的提取液浓度等于或大于0.02 mg/kg /50平方厘米样品表面积。可以看看Redanqi的一个帖子,那上面有些翻译的。

Spot-test:
negative=absence of CrVI coating,positive=presence of CrVI coating
(the tested sample should be further verified by boiling-water-extraction method if the spot test result cannot be confirmed)
boiling-water-extraction:
negative=absence of CrVI coating
positive=presence of CrVI coating;the detected concentration in boiling-water-extraction
solution is equal or greater than 0.02 mg/kg with 50cm2 sample surface areas
抽样测试:
负号=未测出涂层中CrVI 正号=测出涂层中CrVI(如果抽样测试结果没有得到证实,测试样品需要用热萃取法进一步测定)
热萃取法:
负号=未测出涂层中CrVI
正号=测出涂层中CrVI 用样品表面积为50cm2萃取,萃取溶液中的检测浓度要大于等于0.02 mg/kg
