Foreword
This standard replaces GB/T 12827-1991 "Standard reference acetylene black and identification methods."
This standard compared with GB/T 12827-1991 main changes are as follows.
a) increasing the "Preface" and "warning" language;
b) Normative documents using the latest version of the standard number and standard name;
c) increase the "meaning" (Excerpts Chapter 3);
d) Excerpts of the reg number "4 ~ 10" correspond to the 1991 edition of the "3 to 9";
e) The 1991 edition SRABR1 testing program "specific resistance, kΩ · cm" was changed to "resistivity, Ω · m", the standard value "0.20 ±
0.03 "was changed to" 2.0 ± 0.3 "(Excerpts of Table 1);
f) according to GB/T 3781.8 the latest version of "hydrochloric acid liquid absorption test method" changes in Table 1 SRABR1 hydrochloric acid aspiration amount standard value
By the (4.2 ± 0.3) cm3/g modified to (4.0 ± 0.3) cm3/g (Excerpts of Table 1);
g) 1991 edition of the row and column mean the upper and lower control limits and standard deviation formula is wrong, this edition has been corrected (1991 edition

h) deleted "that" content (Chapter 9 1991 edition);
i) Remove the 1991 edition of "additional instructions."
The standard proposed by China Petroleum and Chemical Industry Association.
This standard by the National Rubber and rubber products Standardization Technical Committee of carbon black Technical Committee (SAC/TC35/SC5) centralized.
This standard is drafted by. China Rubber Group Carbon Black Research & Design Institute.
3.1 standard used to ensure that each batch of standard parameters are evaluated according to the same standard procedures than acetylene black.
3.2 standard criteria used to determine the value of acetylene black is used as a reference standard of physical and chemical properties of the product.
4 Standard reference acetylene black standard value
SRAB1 standard values \u200b\u200bas shown in Table 1.
