Complete Guide to IS 694: What You Must Know About Standard PVC Insulated Electrical Wires in India
When it comes to electrical safety and performance, IS 694 stands as one of the most important standards for PVC insulated wires in India. Whether you’re an electrician, a builder, or a homeowner planning a new wiring installation, understanding IS 694 standard can help you choose the right wires that ensure safety, efficiency, and long-term reliability. In this guide, we’ll explore everything about IS 694 PVC insulated electrical wires, their importance, types, construction, testing methods, and why compliance with this standard matters for every home and business in India. What Is IS 694 Standard? IS 694 is a specification issued by the Bureau of Indian Standards (BIS) that defines the quality, construction, and testing requirements for PVC insulated cables used in working voltages up to and including 1100 volts. This standard ensures that electrical wires manufactured under it are safe, durable, and resistant to heat, moisture, and fire hazards. The standard covers single-core and multi-core cables used for: • Domestic wiring • Industrial electrical installations • Power supply systems • Lighting and control circuits In simple terms, IS 694 certified wires guarantee you are using cables that meet India’s highest safety and quality benchmarks. Why IS 694 Matters for Electrical Safety Electrical fires and short circuits are common in India, especially due to poor wiring quality or substandard materials. Using IS 694 PVC wires minimizes these risks significantly. Here’s how: ✅ Fire Resistance: IS 694 wires undergo flame retardancy tests to prevent fire spread. ✅ High Insulation Resistance: Ensures minimal current leakage and prevents electrical shocks. ✅ Durability: Designed to withstand India’s fluctuating temperature and humidity. ✅ Voltage Withstand Test: Each wire passes stringent voltage tests to ensure it can handle rated loads safely. In short, IS 694 ensures your wires don’t just carry current — they protect your home. Construction of IS 694 PVC Insulated Wires IS 694 defines the technical construction of PVC wires to maintain consistency and safety across all manufacturers. Let’s break it down: 1.Conductor Material: Usually copper or aluminium, but copper conductors are preferred for better conductivity and flexibility. 2.Conductor Class: Classified as Class 1 (solid) or Class 5 (flexible stranded) depending on use. 3.Insulation Material: PVC (Polyvinyl Chloride) insulation is used for its flame retardant and heat-resistant properties. 4.Voltage Rating: Designed for up to 1100V applications — suitable for most domestic and commercial wiring. 5.Colour Coding: Wires are color-coded as per IS 694 — red, yellow, blue for phases, black for neutral, and green for earthing. Key Tests Conducted Under IS 694 All these tests ensure the wires perform reliably under Indian conditions.

Applications of IS 694 PVC Insulated Wires IS 694 wires are versatile and widely used in: • Residential building wiring • Office and commercial space electrical setups • Lighting circuits • Industrial machinery wiring • Control panels and switchboards In every case, these wires are preferred because of their safety, long life, and low maintenance. Benefits of Using IS 694 Certified PVC Wires 1.Safety Assurance: Tested against fire, voltage, and insulation failures. 2.Longer Lifespan: High-quality PVC insulation ensures durability in humid and hot climates. 3.Energy Efficiency: Low resistance and high conductivity save power and reduce energy losses. 4.Compliance and Trust: IS 694 certification builds trust among electricians, engineers, and homeowners alike. 5.Cost-Effective: Though slightly more expensive than local non-standard wires, they reduce maintenance and fire hazards, saving money long-term. Deckard Wires — Crafted to Meet IS 694 Standards At Deckard Wires, we don’t just make wires — we engineer safety and reliability. Every wire we produce is IS 694 certified and passes strict quality control checks to meet BIS and ISO standards. Our PVC insulated copper wires are: • Flame retardant (FR / FRLS) • Flexible and easy to install • Resistant to heat, oil, and moisture • Ideal for both domestic and industrial use When you choose Deckard Wires, you’re choosing trusted performance and certified safety. How to Identify IS 694 Certified Wires Always check for the following markings on the wire sheath: • ISI mark (BIS certification mark) • “IS 694” clearly printed • Manufacturer’s name • Voltage rating • Wire size (e.g., 1.5 sq. mm, 2.5 sq. mm) If a wire doesn’t carry this information — it’s best avoided.
