标准范围
This International Standard specifies two methods for the determination of the amount of bale coating present on the outside wrapper sheets of bales of natural rubber:— ashing method;— brushing or scraping method.The ashing method is the preferred method.NOTE 1 The brushing or scraping procedure, while much faster, is not suitable for use on such rubbers which have holes on the surface where coatings could penetrate, making its removal difficult.NOTE 2 The ashing procedure is not suitable for coating materials which are affected by the ashing. In particular, coatings containing carbonates or organic matter can give very low results.
