  • SI units: kilogram, microgram, milligram, gram, ton.
  • Imperial Units: Troy ounce when weighing precious metals.
  • Other non-SI units: metric carat when weighing gems.
• Accuracy. The error display must not exceed the maximum permissible display error. For digital display, the display error must be corrected by the rounding error.

• Electronic devices exposed to interference shall not display or automatically detect and display the effects of significant faults.
• If external devices are connected to an electronic device via a suitable interface, the metrological properties of the device must not be impaired.
• The equipment shall not have features that facilitate fraudulent use and the possibility of unintentional misuse shall be minimal. Components that may not be disassembled or adjusted by the user must be secured against such actions.
• The printed results shall be correct, appropriately labelled and unambiguous. The print must be clear, legible, indelible and durable.
• Where appropriate, the equipment shall be equipped with a levelling device and a level indicator so sensitive that proper installation is possible.

• Kitchen or bathroom scale.
• Scales for retail and industry.
• Weighing systems at supermarket checkouts.
• weighbridges.
• Laboratory and pharmaceutical scales.

• General description of the instrument.

• Descriptions and explanations are required for understanding these drawings and plans as well as for the operation of the device.
• List of fully or partially applied harmonised standards whose references have been published in the Official Journal of the European Union.
• Results of design calculations, tests carried out, etc.
• Test reports.

• The name and address of the manufacturer and, if the application is submitted by the authorized representative, the name and address of the manufacturer.
• A written statement that the same application was not submitted to another notified body.
• All relevant information for the device category is provided.
• Documents on the quality system.
• The technical documentation of the approved type and a copy of the EU type examination certificate.

• The CE marking and the additional metrology marking shall be clearly visible, legible and permanently affixed to the device or its data plate.
• The CE marking and the additional metrology marking shall be affixed before the device is placed on the market.
• The additional metrology marking must be carried out immediately after the CE marking.
• Behind the CE marking and the additional metrology marking is/are the identification number(s) of the notified body.
• The CE marking, the additional metrology marking and the identification number(s) of the notified body(s) may be followed by any other marking indicating a particular hazard or use.

• Device model/device (product, type, batch or serial number).
• Name and address of the manufacturer and, if applicable, his authorized representative.
• The declaration of conformity is issued under the sole responsibility of the manufacturer.
• References to the relevant harmonised standards applied or references to the other technical specifications whose conformity is declared.
• Additional information: Signed for and on behalf of (place and date of issue), (name, function) (signature).

• When placing on the market their equipment intended for the applications referred to in Article 1 paragraph 2 letters a) to f) (all products falling within the scope of the Directive) ensure that they have been designed and manufactured in accordance with the essential requirements set out in Annex I.
• For equipment intended for the applications referred to in Article 1 paragraph 2 letters a to f (all products covered by the Directive) draw up the technical documentation referred to in Annex II and carry out or have carried out the relevant conformity assessment procedure referred to in Article 13. Where this conformity assessment procedure has demonstrated that a device intended for the applications referred to in Article 1 paragraph 2 letters a to f (all products falling within the scope of the Directive) complies with the applicable requirements Manufacturers shall issue an EU declaration of conformity and affix the CE marking and the additional metrology marking.
• For equipment intended for the applications referred to in Article 1, paragraph 2, letters a to f (all products falling within the scope of the Directive), manufacturers shall keep the declaration of conformity for ten years after placing the device on the market.
• Manufacturers shall ensure that conformity with this Directive is maintained during series production. Changes to the design of the device or its features, as well as changes to the harmonised standards or other technical specifications referred to in the declaration of conformity of a device, shall be duly taken into account. If it is considered appropriate in view of the risks posed by a device intended for the applications referred to in Article 1, paragraph 2, letters a to f (all products covered by the Directive), Manufacturers shall carry out sampling of devices made available on the market, investigate complaints, non-compliant devices and device recalls and, where necessary, maintain a list of complaints and keep traders informed of such monitoring.
• Manufacturers shall ensure that the devices they place on the market bear a type, batch or serial number or other identification mark for their identification in accordance with Annex III.

In summary, the conformity assessment requirements for some appliances such as kitchen or bathroom scales are simple for personal use at home. In such cases, only the name of the manufacturer and the weighing range must be indicated on the scale. For other scales, however, NAWI must undergo an EC type-examination and receive an EC type-approval certificate. NAWI must be produced in accordance with the EC type approval certificate.

• The technical documentation and additional evidence shall include, where necessary, the results of tests carried out in accordance with other relevant technical specifications by a suitable laboratory of the manufacturer or by another test laboratory on his behalf and under his responsibility.
• The notified body shall carry out or have carried out the relevant investigations and tests to determine whether the solutions chosen by the manufacturer using the relevant technical specifications comply with the relevant essential requirements of this Directive.
• The notified body and the manufacturer must agree on a place where the tests and tests are to be carried out.

Annex 2 to the Directive lays down the procedure by which either a notified body shall

• Examines and tests the scale and applies the conformity assessment mark
• approve a quality assurance system set up by the manufacturer to meet the requirements of conformity assessment.

In all cases, the established conformity assessment procedure requires the active participation of the notifying bodies in the process.
