Why is NABL Certification Important for Weighing Machines?
Before jumping into the process, it's worth understanding why NABL certification is essential:
It proves your scale has been tested by a government-recognized lab.
It meets the Legal Metrology Act and other regulatory standards.
It enhances accuracy, trust, and audit-readiness.
It is mandatory for participating in many government or corporate tenders.
Now let’s break down the actual process.
Step 1: Share Weighing Scale Details
The first step is gathering the necessary information about your weighing scale:
Model number and capacity (e.g., 30kg, 100kg, etc.)
Type (platform scale, tabletop, industrial, etc.)
Brand or manufacturer
Current condition (new or in use)
Business GST and PAN number
This allows us to identify the correct NABL lab and calibration method suited for your machine.
Step 2: Verification and Scheduling
Our team at Shree Shree Weighing Solutions will:
Verify whether your scale qualifies for NABL calibration
Match it to a NABL-accredited lab closest to your location
Schedule on-site calibration (if possible) or arrange transport to the lab
We work Pan-India, so no matter your location, our experts handle logistics and paperwork.
Step 3: Calibration by NABL-Accredited Lab
Next, your weighing scale is calibrated using certified test weights in a lab that follows ISO/IEC 17025 standards.
Calibration is done with extreme precision.
Environmental factors (temperature, humidity) are accounted for.
A traceable calibration certificate is generated with error limits.
This step ensures that your weighing machine meets the exact government-mandated accuracy levels.
Step 4: Issuance of NABL Certificate
Once calibration is complete:
A NABL-accredited Calibration Certificate is issued.
This certificate includes the traceability chain, measurement errors, environmental conditions, and test results.
The certificate is valid across India and recognized during audits and inspections.
We will send you both physical and soft copies for your records.
Step 5: Recordkeeping and Renewal
NABL certificates typically remain valid for one year. Businesses must maintain the certificate and ensure timely renewal to remain compliant with Legal Metrology laws.
At Shree Shree Weighing Solutions, we maintain a renewal alert system — reminding our clients well in advance to avoid lapses.
Documents Required for NABL Certification
To speed up the process, keep these documents ready:
Company GST certificate
PAN card
Invoice copy of the weighing scale (if available)
Location where the weighing scale is used
Previous calibration certificate (if applicable)
Our team helps you prepare and submit everything — no paperwork stress for you.
