What is a Model Approval Certificate?

A Model Approval Certificate is issued by the Directorate of Legal Metrology, Ministry of Consumer Affairs, Government of India. It is granted after a particular model of a weighing or measuring instrument passes technical testing and is verified to meet the required standards.

This certificate must be obtained before manufacturing, importing, or selling any new model of weighing or measuring device in India.

Who Needs Model Approval?

Model Approval is essential for:

Manufacturers of electronic and mechanical weighing instruments

Importers of foreign-made measuring devices

OEMs launching a new model under their brand

Startups developing innovative measurement technology

If your product falls under the scope of the Legal Metrology (General) Rules, 2011, model approval is a non-negotiable legal requirement.

Why is Model Approval Required?

🔹 Legal Requirement

The Legal Metrology Act mandates that no measuring instrument can be sold in India without prior approval of its model.

🔹 Builds Trust

Having model approval assures customers, dealers, and government bodies that your product meets established performance and safety standards.

🔹 Enables Market Entry

Distributors and institutional buyers often insist on certified models. Model approval is the key to accessing large-scale sales channels.

🔹 Avoids Legal Risks

Selling or distributing non-approved models can attract heavy penalties, including seizure of goods and cancellation of business licenses.

Products That Require Model Approval

A wide range of instruments fall under this requirement, including:

Weighing machines (retail, industrial, lab)

Platform scales

Counter scales

Electronic balances

Fuel dispensers

Water meters

Flow meters

Taxi meters

Automatic rail weighbridges

Volumetric and length measuring devices

Documents Required for Model Approval

The application for model approval must include:

Detailed technical specifications

Schematic diagrams and product drawings

Instruction manual or user guide

Step-by-Step Process for Getting Model Approval

Step 1: Preparing the Application

Gather all technical documents, drawings, and supporting paperwork.

Step 2: Submission to Legal Metrology

Submit the complete application to the Director of Legal Metrology, along with a sample unit of the product.

Step 3: Laboratory Testing

The sample is forwarded to a Government-approved lab (e.g., RRSL) for detailed technical testing. The lab checks for compliance with performance, accuracy, and design standards.

Step 4: Evaluation and Review

After the lab issues a test report, the Legal Metrology authority reviews it. If all standards are met, the approval is granted.

Step 5: Issuance of Certificate

Once approved, a Model Approval Certificate is issued, mentioning the model number and its category.

Certificate Validity and Renewal

Validity: 5 years from the date of issue

Renewal: Can be renewed for another 5 years

Re-Testing: Required if significant technical modifications are made or if standards change

Timelines Involved

The average processing time ranges between 2 to 3 months, depending on the lab’s workload and the complexity of the instrument.

Challenges Faced by Applicants

Many businesses struggle with:

Rejection due to missing documents

Delays in lab testing and communication

Unfamiliarity with the format and expectations of the Legal Metrology Department

Incomplete or inaccurate technical documentation

Errors in coordinating with government labs

These delays can derail product launches and lead to legal complications.
