Problems solved by technology
Traditional proficiency testing samples can be directly measured with a multimeter or resistance meter to obtain accurate resistance values. Based on this, some institutions participating in proficiency testing directly report the test data of multimeters as sampling data for proficiency testing, which does not meet the original intention of proficiency testing activities.

Embodiment Construction
[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0020] The steps of the insulation resistance detection ability verification method of the present invention are as follows:
[0021] 1) At the beginning of each proficiency testing activity, first distribute insulation resistance proficiency testing samples to the departments to be verified;
[0022] 2) Evaluate the insulation resistance detection capability of the department to be verified according to the data sent by the department to be verified.
[0023] Such as figure 1 As shown, the samples used include public terminal 1, housing 2, I gear terminal 3, and II gear wiring 4; the upper surface of the housing 2 can print the unit LOGO, and the side can print the sample name and serial number; two gears Bit terminals 2 and 3, and a common terminal 1 are respectively installed on two opposite end surfaces of the housing 2, and the terminals ...

The invention discloses an insulation resistance detection capability verification method, which comprises the following steps of: 1) distributing an insulation resistance capability verification sample to a mechanism participating in capability verification when capability verification activity is started each time; 2) evaluating the insulation resistance detection capability of the mechanism according to the data sent by the mechanism participating in capability verification; wherein the insulation resistance capability verification sample comprises a shell and an insulation resistance capability verification circuit sealed in the shell, a common wiring terminal and a gear wiring terminal are arranged on the shell, one end of the insulation resistance capability verification circuit is electrically connected with the common wiring terminal, and the other end of the insulation resistance capability verification circuit is electrically connected with the gear wiring terminal; the insulation resistance capability verification circuit is composed of a resistance circuit and two voltage stabilizing diodes which are connected in series with the resistance circuit and have opposite polarities. The method provided by the invention can standardize the operation of the mechanism participating in proficiency testing, and the mechanism participating in proficiency testing is limited to test the resistance value of the sample by using the insulation resistance tester according to the standard method specified in the operation instruction book.
Description
technical field [0001] The invention relates to the technical field of ability verification, in particular to an insulation resistance detection ability verification method capable of preventing the insulation resistance from being tested with a multimeter. Background technique [0002] Proficiency testing is an activity that uses inter-laboratory comparisons to determine the calibration and testing capabilities of laboratories or the testing capabilities of inspection agencies. Proficiency testing activities refer to any interlaboratory comparisons and measurement audits used to assess laboratory competence. Examples include activities run by national or regional accreditation bodies and their partner organisations, government departments or industry organisations, or other providers of formal proficiency testing schemes. [0003] Carrying out proficiency testing activities has a positive effect on relevant aspects related to testing or calibration. For laboratories, it is...
