However, only the highest level of verification is of interest within this document. This design type relies on previously verified HST SI design features rather than design features adapted from hardware implemented for other previously flown and previously known spacecraft systems. The envelope, relative location of subassembly parts, and environmental capabilities may be different from other HST SIs using this design . However, the units in question are systems that would be expected to pass unamended HST SI test procedures, and are expected to be verified using existing HST SI test procedures . Inspection is the verification by visual observation or measurement of something.
Test is the rigorous verification demonstrating compliance.
This involves limit testing, environmental testing, multiple testing, etc. that will fully test and characterize a particular capability. Whenever the CEI Spec. These tables have a three digit decimal extension to delineate sequential table items. This scheme maintains a connection of all the information in the latter table with the main requirement information in Table 1 . An example is the following.
