Foreword
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB/T 9103-1988 “Industrial stearic acids”. Compared
with GB/T 9103-1988, main changes in this Standard are as follows:
-- modified the product classification, stearic acid was modified from original
type 200, type 400, type 800 to type 1840, type 1850, type 1865 and
rubber level (see Clause 3 of this Edition, Clause 2 of Edition 1988);
-- modified technical indicators of saponification value, acid value, iodine
value, titer, moisture, color (see 4.2 of this Edition, 3.2 of Edition 1988);
-- added octadecanoic acid content indicator (see 4.2 of this Edition);
-- deleted inorganic acid indicator (3.2 of Edition 1988);
-- modified inspection rules (see Clause 6 of this Edition, Clause 5 of Edition
1988);
-- modified marks, packaging, transport, storage (see Clause 7 of this Edition,
Clause 6 of Edition 1988).
This Standard was proposed by China Light Industry Federation.
This Standard shall be under the jurisdiction of National Technical Committee
