This document specifies a method for the determination of the volatile fatty acid number of natural rubber latex concentrate. The method is not necessarily suitable for latices from natural sources other than Hevea brasiliensis and is not applicable to compounded latex, vulcanized latex, artificial dispersions of rubber or synthetic rubber latices.
Abstract
Overview
ISO 506:2020 specifies a laboratory method to determine the of natural rubber latex concentrate. The VFA number expresses the grams of potassium hydroxide equivalent to volatile fatty acids in a latex concentrate containing 100 g of total solids. The standard applies to natural Hevea brasiliensis latex concentrates and is intended for compounded or vulcanized latices, artificial dispersions or synthetic rubber latices.
