For testing purposes, the register of the electricity meter shall have a resolution of at least 0,01 units.

INTERNATIONAL STANDARD IEC 62052-11

During this test no flashover, disruptive discharge or puncture shall occur. Tests — Test Sa: Screw connections transmitting contact force and screw fixings which may be loosened and iwc several times during the life of the meter shall screw into a metal nut.

For combined temperature and humidity test, see 6.

If for any reason the insulation tests have to be repeated, then they may be performed on a new specimen. The other end of the voltage circuit shall be connected to earth and the impulse voltage shall be applied between the terminal of the current circuit and earth.

The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. If the meter terminals are marked, this marking shall appear on the diagram.

An optimum pulse transmission 2 is achieved when, under test conditions, the receiving head is aligned with its optical axis on the optical pulse output.

Standard symbols may also be used see IEC For a flush-mounted meter, the meter base may include the sides of the case. The cover shall not be removable without the use of a tool. For special application, other test levels might be necessary and should be agreed upon between the user and the manufacturer. The impulse voltage tests shall be carried out first and the a. Q5 This standard meets my needs: When continuously rotating, the lowest values of the drums shall 662052 graduated and numbered in ten divisions, each division being subdivided into ten parts, or any other arrangement ensuring the same reading accuracy.

After the test, the meter shall show no damage and shall operate correctly. Electromechanical meters for active energy classes 0,5, 1 and 2 Replaces particular requirements of IEC After the test, the meter shall show no damage and shall comply with the dielectric strength tests of 7.

Where there is a difference between the definitions in the glossary and those contained in product standards produced by TC 13, then the latter shall take precedence in applications of the relevant standard. General terms relating to electrical measurements — Part The text of this standard is based on the following documents: Power consumption and voltage requirements IEC It is permissible to indicate the connection eic by an identification figure in accordance with national standards.

Continuous and long duration electromagnetic phenomena are considered as influence quantities and the accuracy requirements are given in the relevant standard. It is usually designed and operated to obtain the highest accuracy and stability in a controlled laboratory environment 3.

Simulated solar radiation at ground level IEC Testing and measurement techniques — Section 2: The holes in the insulating material which form an extension of the terminal holes shall be of sufficient size to also accommodate the insulation of the conductors. 6252 neutral terminal of the meter under test is disconnected from the ground terminal of the meter test equipment MTE and is connected to the MTE’s line terminal at which the earth fault 620052 to be simulated see Annex C.

It does not apply to: Meters are designated by the manufacturer by one or more groups of letters or numbers, or a combination of letters and numbers. Any protective coating shall not be liable to damage by ordinary handling nor damage due to exposure to air, under normal working conditions. Test procedure in accordance with IEC These windows shall be of transparent material which cannot be removed undamaged without breaking the seal s.

After the test, the meter shall show no damage or change of the information and shall operate correctly in accordance with the requirements of the relevant standard. Electrical connections shall be so designed that contact pressure is not transmitted through insulating material.

Information under points ab and c may be marked on an external plate permanently attached to the meter cover. Tests — Tests A: Reference number IEC
