Step-by-Step BIS Certification Process for Hermetic Compressors<\/h2>\n<p>The general BIS certification process under Scheme-I is explained below.<\/p>\n<p><strong>Step 1 \u2013 Product Applicability Assessment<\/strong><\/p>\n<p>Confirm that the compressor falls within the scope of IS 10617:2018 and the applicable Quality Control Order.<\/p>\n<p><strong>Step 2 \u2013 Compressor Category Identification<\/strong><\/p>\n<p>Identify whether the product is LBP, CBP\/MBP or HBP.<\/p>\n<p><strong>Step 3 \u2013 Model and Capacity Mapping<\/strong><\/p>\n<p>Prepare a model-wise list covering cooling capacity, phase and compressor category.<\/p>\n<p><strong>Step 4 \u2013 Product Grouping Assessment<\/strong><\/p>\n<p>Determine the representative models for testing based on the highest cooling capacity in each category and phase configuration.<\/p>\n<p><strong>Step 5 \u2013 Factory Infrastructure Assessment<\/strong><\/p>\n<p>Evaluate manufacturing facilities, testing equipment, laboratory arrangements and quality-control systems.<\/p>\n<p><strong>Step 6 \u2013 Documentation Preparation<\/strong><\/p>\n<p>Prepare the company, manufacturing, technical and quality-control documents.<\/p>\n<p><strong>Step 7 \u2013 BIS Application Submission<\/strong><\/p>\n<p>Submit the application through the applicable BIS certification procedure along with the required documents and prescribed fees.<\/p>\n<p><strong>Step 8 \u2013 BIS Factory Inspection<\/strong><\/p>\n<p>BIS assesses the manufacturing process, product construction, laboratory facilities, testing arrangements and quality-control system.<\/p>\n<p><strong>Step 9 \u2013 Sample Testing<\/strong><\/p>\n<p>The required compressor samples are tested against IS 10617:2018.<\/p>\n<p><strong>Step 10 \u2013 Compliance and Clarifications<\/strong><\/p>\n<p>The manufacturer addresses observations, testing issues or non-conformities raised during the certification process.<\/p>\n<p><strong>Step 11 \u2013 Grant of BIS Licence<\/strong><\/p>\n<p>After satisfactory completion of the applicable assessment and certification requirements, BIS may grant the licence to use the Standard Mark for the approved product scope.<\/p>\n<h2>15. Common Challenges in BIS Certification for Hermetic Compressors<\/h2>\n<p>Manufacturers may face several technical and procedural challenges during BIS certification.<\/p>\n<h3>1. Incorrect Compressor Classification<\/h3>\n<p>Incorrect identification of LBP, CBP\/MBP and HBP categories can result in errors in the proposed licence scope.<\/p>\n<h3>2. Incorrect Product Grouping<\/h3>\n<p>Different compressor capacities and electrical configurations must be considered when selecting representative models for testing.<\/p>\n<h3>3. Lack of Performance Testing Facilities<\/h3>\n<p>Compressor performance testing requires specialised calorimeter facilities and suitable test arrangements.<\/p>\n<h3>4. Electrical Safety Test Failures<\/h3>\n<p>Insufficient insulation, improper electrical connections or design issues may result in failure during high-voltage or leakage current testing.<\/p>\n<h3>5. Shell Leakage and Pressure Test Failure<\/h3>\n<p>Manufacturing defects or inadequate sealing may lead to failures during holding charge, shell leakage or bursting tests.<\/p>\n<h3>6. Inadequate Calibration and Test Records<\/h3>\n<p>The manufacturer must maintain suitable calibration records and documented evidence of routine and type testing.<\/p>\n<h3>7. Incorrect Scope of Licence<\/h3>\n<p>The manufacturer must ensure that the proposed licence scope accurately identifies the compressor category, cooling capacity and phase configuration.<\/p>\n<p>A technical gap assessment before submitting the BIS application can help reduce avoidable testing and certification delays.<\/p>\n<h2>16.

Frequently Asked Questions (FAQs)<\/h2>\n<p><strong>Q1. Is BIS certification mandatory for hermetic compressors in India?<\/strong><\/p>\n<p>Yes. Hermetic compressors covered under the Air Conditioner and its related Parts, Hermetic Compressor and Temperature Sensing Controls Quality Control Order must comply with IS 10617:2018 and obtain the applicable BIS licence, subject to specific exemptions notified by the Government.<\/p>\n<p><strong>Q2. Which Indian Standard applies to hermetic compressors?<\/strong><\/p>\n<p>The applicable standard is IS 10617:2018 \u2013 Hermetic Compressors: Specification.<\/p>\n<p><strong>Q3. Under which BIS scheme is certification granted?<\/strong><\/p>\n<p>Certification is granted under Scheme-I of the BIS (Conformity Assessment) Regulations, 2018.<\/p>\n<p><strong>Q4. What are the main categories of hermetic compressors?<\/strong><\/p>\n<p>The product manual identifies three categories: Low Back Pressure (LBP), Commercial Back Pressure \/ Medium Back Pressure (CBP\/MBP) and High Back Pressure (HBP).<\/p>\n<p><strong>Q5. What is the sample quantity required for BIS certification?<\/strong><\/p>\n<p>The BIS Product Manual PM\/IS 10617\/2\/December 2020 specifies three compressors as the sample quantity.<\/p>\n<p><strong>Q6. What are the grouping parameters for hermetic compressors?<\/strong><\/p>\n<p>The main grouping parameters are compressor category, number of phases and cooling capacity. The highest cooling capacity from each category is tested separately for single-phase and three-phase configurations.<\/p>\n<p><strong>Q7. What are the major tests required under IS 10617:2018?<\/strong><\/p>\n<p>The major tests include compressor performance, startability, locked rotor, high voltage, leakage current, bursting, holding charge, shell leakage, running overload and resistance to rusting.<\/p>\n<p><strong>Q8. Is an in-house laboratory required?<\/strong><\/p>\n<p>The manufacturer must maintain a suitably equipped and staffed laboratory as required by the product manual. Certain tests may be subcontracted to BIS-recognised laboratories or Government laboratories empanelled by BIS, subject to the prescribed provisions.<\/p>\n<p><strong>Q9. Can compressor testing be outsourced?<\/strong><\/p>\n<p>Yes. The product manual permits subcontracting of specified tests to laboratories recognised by BIS or Government laboratories empanelled by BIS.

What is the licence scope for hermetic compressors?<\/strong><\/p>\n<p>The scope identifies the compressor category, cooling capacity and whether the compressor is single phase or three phase.<\/p>\n<p><strong>Q11. Are hermetic compressors below 2 TR exempt from BIS certification?<\/strong><\/p>\n<p>There is no blanket exemption for every compressor below 2 TR. The 2025 actual-user exemption was time-limited, and the 2026 amendment provides a specific exemption for qualifying imports of certain reciprocating hermetic compressors below 2 TR intended for refrigerators and similar refrigeration appliances, subject to quantity and use conditions. The exact Gazette provisions must be checked.<\/p>\n<p><strong>Q12. Can foreign manufacturers obtain BIS certification for hermetic compressors?<\/strong><\/p>\n<p>Foreign manufacturers may apply through the applicable BIS Foreign Manufacturers Certification Scheme (FMCS), subject to eligibility, factory inspection, testing and Authorised Indian Representative requirements.<\/p>\n<p><strong>Q13.
