- Certification for Diesel Generators is mandatory for specific kVA capacities under BIS regulations in India.
- Diesel Generator manufacturers must comply with BIS Scheme X Certification standards for market approval.
- Understand the classification of diesel generators and how it affects certification eligibility.
- Get expert insights on documents, process, validity, benefits, and regulatory compliance from Diligence Certifications.
Introduction
In 2024, a Delhi-based electrical equipment company was held at port for importing 500 kVA diesel generators. Reason? No BIS certification. Despite clearing customs for five years, a new Quality Control Order (QCO) had come into effect under BIS Scheme X. Their shipment worth ₹3 crore sat idle for over two months. This wasn’t an isolated case.
At Diligence Certifications, we’ve seen a surge in queries from diesel generator manufacturers, importers, and OEM suppliers about how BIS applies to their equipment, what capacity thresholds require certification, and what documents are needed. This guide answers all of it – no fluff, just compliance-backed information.
What is BIS Scheme X Certification?
BIS Scheme X is a certification scheme introduced for products that fall under newly notified QCOs, especially electrical machinery like diesel generators. It includes:
- Factory audit by BIS inspectors
- Product sample testing from certified labs
- Ongoing surveillance post-certification
What is Certification for Diesel Generators
A diesel generator is an electric power generation engine governed by a diesel engine. It converts electric energy from chemical energy stored in diesel fuel through mechanical action. DG Sets are normally used as backup power in almost all industries like healthcare, telecom, construction, and manufacturing.
Some assemblies and subassemblies of DG sets include:
-Diesel Engine
-Alternator
-Radiator
-Fuel System
-Control Panel
-Battery and Starter Motor
-Exhaust System
-Base Frame and Vibration Isolators
Depending on the complexity of the individual subassemblies and assemblies and their sensitivity, BIS standards ensure that all individual components conform to certain quality and safety specifications.
Why BIS Certification is Mandatory for DG Sets
BIS Certification denotes:
- Reliably safe and sound
- That is compliance in environment and effectiveness
- Market access and permission to trade
- Greater assurance and trust in consumers’ brands
The Government of India; Quality Control Order notation makes BIS certification mandatory for many products around Diesel Generators and major components among such things.
BIS Certification Scheme for Diesel Generators
Diesel Generators and their parts under BIS Scheme X Certification are largely covered under two categories:
1. ISI Certification Scheme (Scheme I of BIS – FMCS)
The ISI mark under the Foreign Manufacturers Certification Scheme (FMCS) or Domestic Manufacturers Certification Scheme is for those manufacturers who comply with the relevant Indian Standards.
2. Compulsory Registration Scheme (CRS)
Although generally applicable to electronic and IT goods, some sub-assemblies of DG Sets that are more or less related to electronic controls can come under the purview of this scheme.
Benefits of Certification
| Benefit | Impact |
|---|---|
| Compliance | Avoid legal action & penalties |
| Safety | Reduces fire/hazard risks |
| Market access | Mandatory for bids, tenders, exports |
| Consumer assurance | Certified brand outreach + warranties |
| Lower insurance cost | Many insurers offer reduced premiums |
Applicable Indian Standards for Diesel Generators
Here are some of the key Indian Standards that apply to Diesel Generators and their components:
| Product/Component | Indian Standard (IS) | Scope |
| Diesel Engine | IS 10000 Series, IS 13018 | Performance and emissions standards |
| Alternators | IS 4722, IS 13364 | Alternators for automotive applications |
| Diesel Generator Sets | IS 1460, IS 10002 | Complete Genset testing and standards |
| Radiators & Cooling System | IS 10278 | General requirements for radiators |
| Control Panels | IS 8623 (Part 1) | Electrical control panel safety |
| Acoustic Enclosures | CPCB-II Norms, IS 14599 | Noise level and pollution standards |
| Battery & Starter System | IS 13514, IS 14257 | Batteries and starters for DG applications |
| Fuel Tanks | IS 10987 | Fabrication and testing |
| Exhaust Systems | IS 8183 | Emission standards compliance |
Note: The list is indicative. For specific product certification, the applicable standard must be verified with BIS or a certification consultant.
Classification of Diesel Generators for BIS Certification
DG Sets are classified according to:
- Power Output in regards to kVA/kW range;
- Usage such as Residential/Commercial/Industrial;
- Type of Cooling ((Air-cooled, Water-cooled));
- Fuel-Type associated (Standard Diesel or Bio-diesel compatible);
- Compliance Category about CPCB-I, CPCB-II norms.
Each class could, therefore, create new BIS standards or certification requirements.
Certification Requirements for Sub-Assemblies and Components
- Apart from the complete D.G. Sets, various components are individually governed under the BIS regulation. Any manufacturer or importer of such items needs to obtain certification, although they are not manufacturing complete D.G. Sets. Examples would be:
- Engines are tested for emissions, efficiency, and mechanical performance.
- Alternators are validated for voltage regulation, frequency, and thermal performance.
- Control Units must fulfill electrical safety and software control standards.
- Acoustic Enclosures: This is certified for soundproofing effectiveness according to CPCB-II.
Process of BIS Certification for Diesel Generators and Components
1. Determine Applicability
Determine product or component applicability to a mandatory BIS certification scheme. This depends on the Indian Standards notified for that product.
2. Documentation
Prepare necessary documents like:
- Technical Product File
- Factory License and Layout
- Manufacturing Process Flow\
- In-House Testing Facility Details
- Quality Control Procedures
- Test Reports from BIS-recognized labs
3. Application Filing
Apply on the BIS portal online under the relevant scheme (ISI FMCS CRS), upload documents with prescribed fees for the application.
4. Product Testing
Sent those samples to BIS-referred laboratories for examinations of Indian Standards.
5. Factory Inspection
BIS officials may visit compliance and assessment of quality control by any manufacturing unit (domestic or foreign).
6. Grant of License
BIS grants the certification license after a successful inspection and evaluation of test reports. The manufacturer can then place an ISI mark or Standard Mark on the product.
Role of Authorized Indian Representative (AIR) for Foreign Manufacturers
A foreign manufacturer is required to appoint an Authorized Indian Representative (AIR) for BIS. The AIR serves as a local contact to the BIS on behalf of the foreign company.
Diligence Certification provides end-to-end AIR support and documentation management for international manufacturers entering the Indian market.
Cost Involved in BIS Certification
Costs vary depending on the product category and certification scheme but generally include:
- Application Fees
- Product Testing Charges
- Factory Inspection Fees (including travel and accommodation for foreign sites)
- Marking Fees (annual license fee for using ISI mark)
For a cost-effective and transparent quote, Diligence Certification offers personalized consultation.
Validity and Renewal
- In general, an initial BIS license is granted for one or two years.
- Renewal is granted upon submission of an application for renewal, existing test reports, and payment of the applicable fees.
- Ongoing compliance may be ensured by conducting surveillance audits.
Penalties for Non-Compliance
Selling or importing Diesel generators or components that are covered under the mandatory BIS certification without valid licensing is illegal. The following circumstances may arise:
- Seizure of goods
- Heavy penalties and fines
- Blacklisting from future certifications
- Legal prosecution
