4.3 Working out of metrology security of system of diagnosing of availability index of product of headlights of vehicles in conditions "passing light", "headlight" and «total light» at realisation of a standard method of measurements.
The measurement method - definition of force of light of headlights in a condition "passing light" in a direction 34; up from position of the left part svetotenevoj boundaries.
Three servicing deports of automatic telephone exchange (HUNDRED automatic telephone exchanges) in which the analysis according to the standard method of measurements described in characteristics sheet on applied STD has been carried out took part in experiment.
HUNDRED have spent all on four measurements.At holding of experiment the laboratory №1 used a gear for inspection of external light gears (with transmission of results on computer OPK. Results of measurements are output on liquid crystal
The alphanumeric display with illumination. The gear has an exit for informational link with the computer on interface RS-232 (can transmit results of measurements in the computer of a line of the technical control). Measurement ranges: an angle of inclination svetotenevoj boundaries 0-140 °, force of light of external light gears 0-100000 kd, Height of an optical axis of 250-1600 mm.
Technical characteristics of gear IPF Table 4.8.

In L laboratory «3 available there is a Gear for inspection of external light gears С110. Consists of the optical chamber with digital indication and a mobile rack with the orienting device. Transmits the report of measurements in the central computer of a line of the technical control. Technical characteristics С110 Table 4.9.

For level 1 greatest value s takes place in laboratory N 1 and 2; thus = 156,8; the test statistics = 0,5.
For level 2 greatest value 5 takes place in laboratory N I; thus Јs2 = 359,6; the test statistics = 0,4.
For level 3 greatest value s takes place in laboratory N 2; thus Јs2 = 243,3; the test statistics = 0,6.
For level 4 greatest value s takes place in laboratory N 1; thus Јs2 = 382,9; the test statistics = 0,6.
The received results mean, that all observations are correct, therefore there is no necessity for application of criterion Grabbsa.

Average values of standard aberrations fy and srj can be used.
So, measures pretsizionnosti have following values:
Standard aberration of recurrence s, =9,620589;
Standard aberration of reproducibility 5Л=10,36927.
Further we substitute the received values in expressions for errors of the first and second sort and it is definitively received Pj=0,034 and Р2=0,05 - in the conditions of recurrence both Pj=0,058 and Р2=0,064 - in the conditions of reproducibility.
