ISO 8988:2006 specifies three methods for the determination of the hexamethylenetetramine ("hexa") content of phenolic resins: a Kjeldahl method; direct titration with perchloric acid; potentiometric titration with hydrochloric acid.
Abstract
Overview
ISO 8988:2006 specifies three validated analytical methods for the determination of content in . The standard (third edition, 2006) defines the , a , and a . It gives procedural steps, required reagents and apparatus, applicability limits, safety notes and reporting requirements for reliable quantification of hexa in thermosetting phenolic resin systems.
