119 4 Quality assessment procedures
120 4.1 General
121 Subclauses 4.2 to 4.3 provide recommended ratings, performance and test conditions to be
122 considered when writing a detail specification (DS). They also provide an appropriate
123 schedule of tests with minimum levels of conformance inspection sampling, together with the
124 pro forma blank detail specification (BDS) and instructions for the preparation of a detail
125 specification.
126 4.2 Ratings and characteristics
127 Preferred climatic categories are given in Table 7
128 The values indicated below are recommended for HN series RF connectors and are given for
129 the writer of the detail specification. They are applicable for the condition when the
130 connectors are fully mated. Rating and characteristics are given in Table 8.
131 Certain tests are listed without any recommended values being given. These tests will usually
132 not be required. When these tests are required, appropriate values shall be entered in the
133 detail specification at the discretion of the specification writer.
134 Table 7 – Preferred climatic categories
