This specification covers the requirements for four types of nitric acid propellant.

The nitric acid will be of the following types as specified (6.2):

The types of nitric acid are as follows:

     Type IIIA  - Nominal 14 percent NO2 content plus corrosion inhibitor

     Type IIIB  - Nominal 14 percent NO2 content, lower solids content, plus
                  corrosion inhibitor

     Type IIILS - Limited storage propellant with nominal 14 percent NO2
                  content, lower solids content, plus corrosion inhibitor, and
                  limited iron content

     Type IV    - High density propellant with nominal 44 percent NO2 content,
                  lower solids content, plus corrosion inhibitor, and limited
                  iron content
