1 Scope This part in GB/T 3780 specifies test methods for iodine adsorption number of rubber grade carbon black and acetylene black. This Part is applicable to every kind of rubber grade carbon black (S series, aerating and natural gas channel black excluded) and acetylene carbon black. Note: The iodine adsorption number will be influenced by surface porosity and volatility as well as the presence of extraction. 2 Normative References The following standards contain provisions which, through reference in this part of GB/T 3780, constitute provisions of this part. For dated reference, subsequent modification to, or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this Part are encouraged to study whether the latest edition of these documents is applicable. For undated references, the latest edition of the normative document is applicable to this part.
