Natural rubber in bales - Amount of bale coating - Determination - Third Edition
N 1434
Annotation
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.
