Reviews for measuring instruments

Consideration of the application for testing the legally controlled measuring instruments in accordance with the Law on metrology, § 19, clauses 5 and 6

The testing the legally controlled measuring instrument shall be carried out upon a written order.

The test may be carried out:

• in the laboratories of SLM in absence of the customer’s representative, the personal take-over of the measuring instrument shall be documented in the take-over report, signed by the representatives of both parties – customer and contractor. The take-over is performed by a technical employee of SLM. In this case, the measuring instrument shall be taken over and visually inspected (including taking a photo thereof) under personal presence of the customer´s representative in working days from 08:00 am to 14:00 pm
• in the laboratories of SLM in the presence of the customer´s representative, the attendance list of the participants in the test shall be made
• in the premises of the subcontractor, the attendance list of the participants in the test shall be made

SLM shall perform the examination of the equipment and staff once a year, or after any changes in the respective facts, elaborating a record thereof. In addition to the written documentation, the employee of SLM shall arrange the photo documentation of the measuring instrument presented for the tests (as a part of the measuring instrument inspection). The photos shall be taken in a manner enabling to see the condition of the verification and sealing marks, the state of the counter before the test, or possible visible defects of the measuring instrument. Every photo shall be identifiable (visible serial number of the respective measuring instrument). In case when SLM takes over the measuring instrument in the absence of the customer´s representative on the test, the paper photo documentation shall be signed by the representatives of both parties (SLM and customer).

Methodical procedure of testing the legally controlled measuring instruments according to the Law on metrology § 19, clauses 5 and 6:

The measuring instrument is tested within the range of the verification tests – in accordance with the Law on metrology, § 15 clause 7. The test procedures are in compliance with the legal rules and working procedures currently in force. The test consists particularly of the following operations:

1. examination of the equipment and personnel (when the test is performed in the premises of a subcontractor);
2. preparation of the attendance list of the persons presented on the test (when the test is performed in the premises of the subcontractor or in the laboratories of SLM in the presence of the customer’s representative);
3. inspection of the measuring instrument (including photo documentation);
4. testing the measuring instrument metrological characteristics, elaboration of the record of measurement (in accordance with the respective working procedures and legal rules in force);
5. evaluation of the maximum permissible errors and their recording in the record on measurement;
6. after the test, an evaluation of results is performed and documented in the test report to the measuring instrument in accordance with § 19, clauses 5 and 6 with the following sentence and final conclusion:

I.

1. “the water meter ” complies/does not comply with the requirements specified in the § 19, clause 6 of Act No 142/2000 Coll. as later amended, and with the requirements of the Annex No 8 to the UNMS SR Ordinance No 210/2000 as later amended;
2. “the gas meter ” complies/does not comply with the requirements specified in § 19, clause 6 of Act No 142/2000 Coll. as later amended, and with the requirements of the Annex No 13 to the UNMS SR Ordinance No 210/2000 as later amended;
3. “the heat meter” complies/does not comply with the requirements specified in § 19, clause 6 of Act No 142/2000 Coll. as later amended, and with the requirements of the Annex No 51 to the UNMS SR Ordinance No 210/2000 as later amended;
4. “the active electric energy meter” complies/does not comply with the requirements specified in § 19, clause 6 of Act No 142/2000 Coll. as later amended, and with the requirements of the Annex No 14 to the UNMS SR Ordinance No 210/2000 as later amended;

II.

1. “the water meter ” complies/does not comply with the requirements specified in § 19, clause 6 of Act No 142/2000 Coll. as later amended, and with the requirements of the MI-001 to the Government Ordinance No 294/2005 on measuring instruments as later amended;
2. “the gas meter ” complies/does not comply with the requirements specified in § 19, clause 6 of Act No 142/2000 Coll. as later amended, and with the requirements of the MI-002 to the Government Ordinance No 294/2005 on measuring instruments as later amended;
3. “the heat meter ” complies/does not comply with the requirements specified in § 19, clause 6 of Act No 142/2000 Coll. as later amended, and with the requirements of the MI-004 to the Government Ordinance No 294/2005 on measuring instruments as later amended;
4. “the active electric energy meter ” complies/does not comply with the requirements specified in § 19, clause 6 of Act No 142/2000 Coll. as later amended, and with the requirements of the MI-003 to the Government Ordinance No 294/2005 on measuring instruments as later amended.

Generally said: The legally controlled measuring instrument is considered that it passed the test if its error does not exceed the maximum permissible errors specified by law.

The results of inspection do not influence the final conclusion (they are stated in the test report and in the record on measurement).

In case, the verification/sealing mark is damaged, changed or removed, a brief description of the damage, change or removal shall be stated both in the record on measurement and in the test report (in the parts concerning the status of the verification and sealing marks).
