Standard Guide for Preparation of Binary Chemical Compatibility Chart
SCOPE
1.1 A binary chemical compatibility chart (also called inter-reactivity chart) compares the hazards associated with the mixing of two different materials. This guide provides an aid for the preparation of these charts. It reviews a number of issues that are critical in the preparation of such charts: accurate assessment of chemical compatibility, suitable experimental techniques for gathering compatibility information, incorporation of user-friendliness, and provision for revisions.
1.2 The uses of chemical compatibility charts are summarized in this standard.
1.3 This guide also reviews existing public domain compatibility charts, the differences therein, and their advantages and disadvantages.

the Preparation of a Binary Chemical Compatibility Chart
This standard is issued under the fixed designation E 2012; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
In 1982, ASTM Committee D-34 on Hazardous Waste proposed the compatibility chart PS 168 that
is discussed in this standard. ASTM Committee E-27 (sponsors of this standard guide) raised several
issues as to the accuracy of parts of the chart that ultimately led to the withdrawal of the proposed
standard and the tacit agreement of E-27 to take over further development. As time passed, it became
increasingly clear that a consensus chart, agreeable to all, and comprehensive enough to be useful to
the chemical industry was and still is a difficult task. Consequently, Committee E-27 embarked on an
easier but nonetheless very useful task that provides expert guidance to those who might be interested
in the task of compiling compatibility information without actually dictating the answers to specific
binary reactivity questions. This standard is the result of that effort. It is the Committee’s belief that
inter-reactivity charts will be increasingly used in industry for day-to-day operations, process hazard
reviews, employee education, and emergency response. It is our hope that this standard guide can be
useful in that effort.
