This standard specifies the method for the determination of pectin content in papermaking raw materials. This standard applies to the determination of pectin content in various papermaking raw materials. This standard provides two methods for the determination of pectin content, namely the gravimetric method and the carbazole colorimetric method, both of which are equally effective.
