6.5 Hose assemblies. When hose assemblies are produced, they need to conform to quality
6.6 Definitions. For the purpose of this specification, the following definition applies.
6.6.1 Stabilization temperature. Temperature which, within 6 inches of an object, does not change
more than +10°F, -5°F (+5.55°C, -2.78°C) per hour.
6.7 Environmentally preferable material. Environmentally preferable materials should be used to the
maximum extent possible to meet the requirements of this specification. As of the dating of this
document, the U.S. Environmental Protection Agency (EPA) is focusing efforts on reducing 31 priority
chemicals. The list of chemicals and additional information is available on their website
https://www.epa.gov/osw/hazard/wastemin/priority.htm. Included in the EPA list of 31 priority chemicals
are cadmium, lead, and mercury. Use of these materials should be minimized or eliminated unless
needed to meet the requirements specified herein (see section 3).
6.7.1 Passivation. Nitric acid is a highly corrosive and toxic strong acid that can cause severe burns.
Citric acid is naturally found in citrus fruits. It easily mixes into liquids, making it a valuable acid. Lemons
and limes have high concentrations of citric acid, accounting for their bitter taste. In industry, citric acid
can be used to make good "natural" cleaners. One of the best benefits of citric acid in all its applications is
that it is natural and poses little to no risk to the environment.
