请大虾们帮忙翻译一下这段关于测试六价铬的:
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
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。
