Scales are equipment used across various fields — from trade and retail to manufacturing and industry, as well as in medicine, laboratories, transport, and logistics. Since they are used in commercial and business activities, certification of weighing instruments is a mandatory requirement. It does not matter what type of equipment is used: pallet, beam, platform, or bench scales. You may also use retail scales, crane (hook) scales, or pallet trucks with built-in weighing systems — all these devices require proper documentation.

What documents are required for scales

To issue or receive goods, scales are needed. For this equipment, the following documents are required:

Passport (User Manual). Regardless of the type of equipment purchased, it must come with an instruction manual. It includes not only technical specifications — the manufacturer also describes rules for operation and storage, as well as safety precautions.

Quality Certificate for Scales. This document contains information about the device’s parameters and its compliance with technical regulations, as well as national or international standards.

Metrological Inspection Logbook. Such a document must be kept by enterprises. It records the date of each inspection and the due date for the next one.

Service Agreement. This mainly applies to heavy-duty scales — for example, crane or beam models.

If a new weighing device is installed at an enterprise, in some cases, a commissioning report may be required. This document confirms that the equipment meets all standards and is approved for use.

Are scales subject to mandatory certification?

The Quality Certificate is the main document required for the sale and use of scales. Any customer may request this certificate, and the seller is obliged to provide it. The document has a defined validity period (specified in the technical passport). Once it expires, pallet, platform, or crane scales must be recertified.

The certification procedure is carried out by state testing bodies, which operate in many cities. To perform a conformity assessment of the weighing instruments, you simply need to contact the nearest certification center.

What is required to certify industrial weighing equipment

Certification of weighing devices guarantees the accuracy and reliability of measuring instruments. Industrial scales determine the weight of various loads, including metal structures. In addition to standard tests, additional examinations are performed. Specialists check how the equipment functions under vibration — it must display accurate results. Accuracy is also tested in dusty environments and at high temperatures.

Certification also includes an analysis of crane (hook) scale resistance to overloads, which can occur during the handling of heavy goods.

Re-certification requirements: what documents must accompany scales

If you need to obtain documentation allowing the use of weighing devices, the following documents are required:

  • Application form

  • Technical passport of the scales

  • User manual

  • Test reports (if available)

  • Supply contract

Note: If you use scales from a foreign manufacturer, an invoice may also be required.

Manufacturer and supplier information must also be provided. The metrological authority may request additional documentation if necessary.

To answer the question, “Is a certificate required for scales?” — yes, it is mandatory.
Only certification ensures measurement accuracy, protects against regulatory penalties, and confirms that the equipment complies with quality and reliability standards.
