    Abstract - (Show below) - (Hide below)

    ISO 8312:2015 defines stearic acid (including blends of stearic and palmitic acid) for use as a compounding ingredient in the rubber industry and specifies the test methods for describing its properties.

    Classification of stearic acid and stearic acid/palmitic acid blends according to iodine value and typical chemical and physical properties for such materials for use in the rubber industry are given in Annex L. Annex L is given for information only.

    In this International Standard, the atomic absorption spectrometric method is the preferred method.
