Hand-Held Electric Circular Saws 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 5):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 5):2023 — Hand-Held Electric Circular Saws (primary standard)
- Aligned with the corresponding IEC / ISO standard for technical performance and safety
- Latest amendments notified by BIS apply automatically
📌 Circular saws are critical for wood, metal, and masonry cutting — and one of the most safety-sensitive power-tool categories. The QCO enforces blade-guard performance, kick-back protection, and electrical safety to protect users from severe injury.
🔬 Key Quality Requirements Under IS 4665 (Part 2/Sec 5):2023
BIS-approved laboratories evaluate the following during type testing:
Blade-Guard & Riving Knife
Upper and lower blade guard retention, return-spring performance, and riving knife alignment per IEC 60745-2-5.
Electrical Safety
Insulation, dielectric strength, leakage current, and earthing. Double-insulation verification on class II tools.
Kick-Back Protection
Anti-kickback design verification. Spindle lock retention under load. Switch design preventing accidental restart.
EMC & Marking
EMC compliance. Voltage, wattage, blade diameter, max cutting depth, and ISI Mark plus licence number on tool body.
Products covered under IS 4665 (Part 2/Sec 5):2023:
- Wood-cutting circular saws — professional and consumer ranges
- Metal-cutting circular saws — abrasive and TCT variants
- Masonry / tile circular saws — diamond-blade types
- Plunge saws and track saws (within hand-held scope)
📋 Step-by-Step BIS ISI Certification Process
- Tool Type IdentificationClassify wood-cutting, metal-cutting, or masonry circular saw. Different blade specifications require separate testing.
- 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 tools to a BIS-recognised power-tool testing laboratory. Electrical, mechanical, and blade-guard tests: approximately 4–6 weeks.
- Factory InspectionBIS officers inspect motor winding, blade-guard assembly, switch mechanism, 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 blade diameter, wattage, and max cutting depth
- Engineering drawings and BOM with critical-component specs
- Blade-guard and riving-knife design records
- EMC test plan and product safety documentation
- 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 lower blade-guard return failure, riving-knife mis-alignment, kick-back during ripping tests, motor overheating, and incomplete markings of max cutting depth.
🏭 Special Considerations for Importers
Circular saws are imported in volume from Germany, China, and Japan. Each variant requires its own BIS ISI certification. Construction-tool importers must hold valid BIS documentation before customs clearance.
