在角度块检定规程中规定,一级角度块工作角的极限偏差应不超过±10″;二级角度块应不超过±30″。但是在检定结果的处理中又规定,对于一级角度块,经检定后其工作角的实际角度对它的标称角度的偏差在±8.5″范围内时,按一级角度块处理,超过了±8.5″时,则按二级角度块处理。对于二级角度块经检定后,其工作角的实际角度对它的标称角度的偏差在±27″范围内时,按二级角度块处理,超过了±27″时,则按不合格处理。
In the angle block verification procedures, the limit deviation of the working angle of the first angle block should not exceed ± 10 “; the second angle block should not exceed ± 30”. However, in the processing of the test results, it is also stipulated that for the first-grade angle block, the actual angle of the working angle after verification is within the range of ± 8.5 “from the nominal angle of the first-degree angle block, ± 8.5 ”, then according to two angle block processing. For the secondary angle block after verification, the actual angle of its working angle deviation from its nominal angle within the range of ± 27 “, according to the second-degree angle block processing, more than ± 27”, according to the failure of processing .
