Standard Practice for Carbon Black—Evaluation of an Industry Reference Black

SIGNIFICANCE AND USE
3.1 These guidelines are intended to ensure that IRBs are evaluated by a standard procedure.  
3.2 These guidelines are to be used to establish the average physicochemical and physical rubber properties of a lot of carbon black to be used as an IRB.
SCOPE
1.1 This practice covers guidelines for the production and testing for uniformity of a lot of carbon black to be used as an Industry Reference Black (IRB).  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

4. Production, Quality Control, and Quality Assurance
4.1 It is assumed that the manufacturer of the IRB will use state-of-the-art techniques to ensure maximum uniformity throughout
the entire production run. The production should be made in one continuous production lot run. The testing called for in this
practice is not intended to be a substitute for in-process quality control. This interlaboratory study is only adequate to verify the
quality of a homogeneous lot.
4.2 The size of the lot is determined by historical records on the rate of use. The lot should have an expected life of 8 to 10
years at the most recent rate of use.
4.3 The black should be bagged in 50-lb polyethylene bags to reduce moisture incursion. Each pallet of bagged black should
be wrapped in plastic to reduce environmental exposure. D
