Standard Specification for Toluene for Toluene Diisocyanate (TDI) Feedstock
ABSTRACT
This specification covers toluene for toluene diisocyanate (TDI) feedstock. The purity, acid wash color, benzene, nanoromatics, ethylbenzene, xylenes, and appearance of toluene shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers toluene for toluene diisocyanate (TDI) feedstock.
1.2 The following applies to all specified limits in this specification: for purposes of determining conformance with this specification, an observed value or a calculated value shall be rounded off to the nearest unit in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29.
1.3 Consult OSHA regulations and supplier’s Safety Data Sheets for all materials used in this specification.
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.5 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.
