Overview & Testing Facility
Located in Bhopal, Madhya Pradesh, CENTRAL POWER RESEARCH INSTITUTE (CPRI), BHOPAL is a prominent government testing laboratory recognized by the Bureau of Indian Standards (BIS). The facility is dedicated to conducting stringent conformity assessment, physical testing, and chemical evaluation to support statutory compliance for domestic manufacturers and global importers.
BIS Recognition & Accreditation Scope
The laboratory operates under BIS certificate number BIS OSL 8100924, valid through 30-06-2027. Its scope is registered under the BIS Laboratory Information Management System (LIMS) covering BIS Recognized Laboratory Scope. All test protocols adhere to the relevant Indian Standards (IS), ensuring that testing results and inspection records maintain full legal validity for BIS License grant, renewal, and surveillance verification.
Testing Capabilities & Methodologies
Equipped with calibrated precision instruments and climate-conditioned test bays, the testing team evaluates materials against mandatory quality control orders (QCOs):
- Standard Verification: Complete physical, mechanical, and safety evaluation conforming to applicable Indian Standards (IS).
- Calibration Traceability: All measuring equipment maintains unbroken calibration chains traceable to national physical standards.
- Quality Assurance: Stringent blind sample testing, round-robin inter-laboratory comparisons, and documented test repeatability.
Sample Submission & Testing Workflow
Manufacturers, brand owners, and compliance consultants can submit product samples for testing through the following procedure:
- Test Request Registration: Submit the formal Test Request Form (TRF) specifying the Indian Standard (IS), product category, and model ratings.
- Sample Dispatch & Chain-of-Custody: Provide requisite sealed sample units with clear serial labeling and technical datasheets.
- Conditioning & Evaluation: Samples undergo environmental pre-conditioning followed by comprehensive standard parameter evaluations.
- Test Report Issuance: A comprehensive, tamper-evident test report is generated and uploaded for BIS compliance submission.
Turnaround Time & Commercial Terms
The standard turnaround time for sample testing is typically 5 to 10 business days from the receipt of complete physical samples and technical documentation. Express testing may be arranged depending on laboratory bay availability. Testing charges are structured in line with standard BIS guidelines based on the volume of parameters and test durations.
