Model Approval

What is LM Model Approval?

Model Approval is a mandatory certification under the Legal Metrology Act, 2009 for manufacturers and importers of weighing and measuring instruments. It verifies that a specific model of the device meets all prescribed technical and performance standards.

Before any weighing or measuring instrument can be sold in India, it must receive Model Approval from the Legal Metrology Department. This ensures accuracy, reliability, and compliance with national metrology standards, preventing errors and consumer disputes.

Model Approval plays a crucial role in maintaining uniformity and accuracy across all weighing and measuring instruments used in trade, industry, laboratories, and commercial applications. It certifies that the instrument’s design, functioning, and construction meet national and international metrology norms.

Once a model is approved, the manufacturer or importer can produce, import, or distribute instruments under that model without needing approval for each individual unit. This enhances business credibility and ensures smooth market entry.

The process involves submitting detailed technical drawings, specifications, performance test reports, and samples to the Legal Metrology Model Approval laboratory. After evaluation and compliance verification, the department grants the approval certificate, valid nationwide.
