A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. Hydrogen bromide generated in situ by the addition of perchloric acid to the quaternary ammonium halide rapidly opens the oxirane ring. As the reaction progresses, the potential will gradually increase until the reaction nears completion at which point the potential increases very quickly.

The titrator measures the rate of the reaction by calculating the change in potential between perchloric acid addition increments.

When the change in potential begins to decrease, the titrator determines that the titration is complete. The epoxide content is calculated using the reagent factor entered by the user during standardization, the weight of the sample, and the volume of perchloric acid added during titration.

The values given in parentheses are for information only. 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.
