Corrosive gasses and particulates
Plan for air quality that meets standards for corrosive gases and particulates.
The storage system is designed to operate reliably in a general business-class
environment. A general business-class environment is one that has automated
24x7x365 temperature and humidity controls and also operates with G1
specifications for corrosive gases and P1 specifications for particulates.
Operating vibration and shock requirements
The vibration levels that are designed for the storage system comply with class V1
requirements included in the product classes for vibration.
The storage system is designed to operate under the vibration V1 levels that are
described in Table 88 on page 166. Additional information includes random
vibration PSD profile breakpoints and operational shock levels. See Table 89 on
page 166 and Table 90 on page 166.
