- Scope
- This International Standard specifies a method for the determination of the sludge content of natural rubber latex concentrate. The method is not necessarily suitable for latices from natural sources other than Hevea brasiliensis. It is not suitable for compounded latex or vulcanized latex. The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. 3 Principle A test portion is centrifuged and the resultant sludge washed repeatedly with ammonia-alcohol solution. The sludge is then dried to constant mass. 4 Reagents During the analysis, use only reagents of recognized analytical grade and only distilled water or water of equivalent purity. 4.1 — — — Ammonia and alcohol, solution having the following composition: ammonia solution, ρ (0,90 ± 0,02) g/cm310 cm3340 cm3 ethanol, 95 % (by volume) minimum purity 1000 cm3 water 5 Apparatus Use ordinary laboratory apparatus and the following. 5.1 Centrifuge, producing a mean acceleration of approximately 12000 m/s2 (1200 g), with two 50 cm3 conical centrifuge tubes or round centrifuge tubes. 5.2 Pipette, of suitable capacity, having a tip opening of diameter approximately 2 mm. 6 Sampling Carry out sampling in accordance with one of the methods specified in ISO 123.
