This document specifies two methods (Method A and Method B) for determining the resistivity of acetylene black.
It applies to acetylene black products.
2 Normative References
The following documents contain provisions which, through reference in this text, constitute essential requirements:
GB/T 3780.8 Carbon Black — Part 8: Determination of Heating Loss
GB/T 3782 Acetylene Black
GB/T 8170 Rules for Rounding Off Numerical Values and Expression of Limiting Values
GB/T 12804 Laboratory Glassware — Measuring Cylinders
GB/T 12827 Standard Reference Acetylene Black and Identification Method
3 Terms and Definitions
This document contains no terms requiring definition.
4 Principle
The sample is thoroughly mixed with dibutyl phthalate to form a uniformly dispersed slurry. The resistivity of the slurry is measured to characterize the conductivity of acetylene black.
