scope:

This standard describes both dry potassium permanganate (KMnO₄) crystals, CAS* No. 7722-64-7, as well as liquid sodium permanganate (NaMnO₄) solutions, CAS* No. 10101-50-5, for use in the treatment of potable and reuse or reclaimed water and wastewater.

Purpose

The purpose of this standard is to provide the minimum requirements for dry potassium permanganate crystals and liquid sodium permanganate solutions, including physical, chemical, sampling, testing, packaging, and shipping requirements.

Application

This standard can be referenced in documents for purchasing and receiving permanganates and can be used as a guide for testing the physical and chemical properties of permanganate samples. The stipulations of this standard apply when this document has been referenced and then only to permanganates used in potable, wastewater, and reuse or reclaimed water.
