1.2.3.1 Replacement or maintenance (applicable to .1 and .5 percent tolerances). It is preferred that resistance values be selected as specified in MIL-PRF-26. However, if it is impracticable to do so, then any value (within specification limits) may be specified and these values shall be considered as conforming to the specification.
1.2.4 Resistance tolerance The resistance tolerance is identified by a single letter in accordance with table II.
