Hand-Held Electric Spray Guns for Non-Flammable Liquids are subject to mandatory BIS ISI certification under the Safety of Hand-held Motor-Operated Electric Tools (Quality Control) Order, 2026. From 12 mo after publication of the QCO in the e-Gazette, these products cannot be lawfully manufactured for sale, imported, or distributed in India without a valid BIS ISI licence under IS 4665 (Part 2/Sec 7):2023. Non-compliance attracts penalties under the BIS Act, 2016 — product seizure, fines, and prosecution.
This guide covers the applicable Indian Standard, key technical and safety requirements, the step-by-step certification process, documentary requirements, and the most common compliance pitfalls for manufacturers and importers.
📜 Applicable Indian Standard
- IS 4665 (Part 2/Sec 7):2023 — Hand-Held Electric Spray Guns for Non-Flammable Liquids (primary standard)
- Aligned with the corresponding IEC / ISO standard for technical performance and safety
- Latest amendments notified by BIS apply automatically
📌 Electric spray guns power painting, agricultural spraying, and surface coating. The QCO enforces electrical safety, spray performance, and durability — ensuring user safety in everyday and professional applications.
🔬 Key Quality Requirements Under IS 4665 (Part 2/Sec 7):2023
BIS-approved laboratories evaluate the following during type testing:
Electrical Safety
Insulation, dielectric strength, leakage current, and earthing per IEC 60745-2-7. Liquid-ingress (IPX) protection verification.
Spray Performance
Spray pattern uniformity, atomisation quality, flow rate, and viscosity-range performance per the cited standard.
Mechanical Durability
Pump / turbine endurance under prescribed cycles. Nozzle wear and trigger mechanism life testing.
Marking & Documentation
Voltage, wattage, max flow rate, viscosity range, intended liquid (non-flammable only), and ISI Mark plus licence number on the tool body.
Products covered under IS 4665 (Part 2/Sec 7):2023:
- Electric paint spray guns for DIY and water-based paint application
- Garden and pesticide spray guns — non-flammable liquid applicators
- Cleaning solution sprayers for industrial cleaning
- Texture / coating spray guns for wall texture and finish applications
📋 Step-by-Step BIS ISI Certification Process
- Liquid Compatibility ConfirmationConfirm intended liquids are non-flammable. Flammable-liquid spray guns require intrinsically-safe certification, not this Section.
- Application FilingSubmit online application on manak.bis.gov.in. Indian manufacturers via Product Certification Scheme; foreign manufacturers via FMCS with appointed AIR.
- Sample TestingSubmit complete spray guns to a BIS-recognised power-tool testing laboratory. Electrical, spray, and endurance tests: approximately 4–6 weeks.
- Factory InspectionBIS officers inspect motor, turbine / pump, nozzle assembly, and in-house testing capability.
- Licence GrantBIS issues the ISI Mark licence. ISI Mark plus licence number is applied on the tool body and packaging.
- Surveillance & RenewalPeriodic BIS market sample testing, factory audits, and annual marking fees keep the licence active.
📄 Documents Required
- Company incorporation / registration certificate
- Product list with wattage, flow rate, viscosity range
- Engineering drawings and BOM with critical-component specs
- Intended-liquid compatibility documentation
- Process flow chart for motor and pump assembly
- Quality Manual / ISO 9001 certificate (if available)
- AIR appointment letter (for foreign manufacturers)
- Existing test reports from BIS-recognised labs (if any)
⚠ Common Compliance Pitfalls
Common issues include nozzle wear within endurance limits, motor overheating, liquid ingress into electrical compartments, and inadequate markings of intended-liquid restrictions.
🏭 Special Considerations for Importers
Electric spray guns are imported for painting, garden, and cleaning applications. Each variant requires its own BIS ISI certification. Importers must hold valid BIS documentation before customs clearance.
