Rubber, natural latex concentrate - Determination of KOH number (ISO 127:2012)
Naturkautschuk-Latex-Konzentrat - Bestimmung der KOH-Zahl (ISO 127:2012)
Overview
This document contains the German translation of International Standard ISO 127:2012 which has been prepared by Technical Committee ISO/TC 45 "Rubber and rubber products", SC 3 "Raw materials (including latex) for use in the rubber industry". The responsible national committee is Working Committee NA 062-04-35 AA "Rohmaterialien (einschließlich Latex) für die Kautschukindustrie" ("Raw materials (including latex) for use in the rubber industry") at the Materials Testing Standards Committee (NMP). This International Standard specifies a method for the determination of the KOH number of natural rubber latex concentrate which is preserved wholly or in part with ammonia. The method is applicable to lattices containing boric acid; however, it is not applicable to latices preserved with potassium hydroxide. It is not necessarily suitable for latices from natural sources other than Hevea brasiliensis, or for latices of synthetic rubber, compounded latex, vulcanized latex or artificial dispersions of rubber.
