Plug into Safety With Standardized Cord Extensions

Cord extension sets are indispensable in modern households and workplaces, providing flexibility and convenience for powering multiple devices. However, their safety and durability are crucial to prevent accidents such as electrical faults, overheating, or misuse. To address these concerns, the IS 18830 standard lays out stringent safety requirements for cord extension sets.

Scope of IS 18830

This standard applies to rewireable, non-rewireable, and integrated cord extension sets, with or without earthing contact, intended for household and similar purposes. Key specifications include:

• Rated Voltage: Between 50 V and 250 V.
• Rated Current: Not exceeding 16 A.
• Applications: Suitable for both indoor and outdoor use.

The standard excludes cord extension sets with built-in mechanisms for reeling.

Key Safety Features of IS 18830

1. Protection Against Electric Shock The standard mandates robust designs to prevent accidental contact with live electrical parts. This is crucial for user safety in everyday scenarios, such as handling the device in wet or dusty environments.
2. Resistance to Ageing and Environmental Factors Cord extension sets are often subjected to harsh conditions, including heat, moisture, and physical wear. The standard ensures that these products withstand ageing, water ingress, and other environmental stresses without compromising safety.
3. Breaking Capacity and Mechanical Strength To handle sudden surges in electrical load or mechanical strain, the standard specifies rigorous testing for breaking capacity and structural integrity. This ensures that the cord extension sets maintain their functionality even under demanding conditions.
4. Reliable Construction Cord Extension Sets must be designed for reliable, danger-free performance during normal use. This includes requirements ensuring proper electrical contacts and secure connections, adequate strain relief mechanism to prevent loosening of wires, screws and nuts to prevent electrical hazards.

Marking Requirements

To promote safe usage and proper identification, IS 18830 mandates clear markings on all cord extension sets. These include:

• Rated Current (in A) and Voltage (in V).
• Nature of Supply: Indicated as a.c. (alternating current).
• Manufacturer or vendor details such as name or trademark.
• Type Reference: A catalogue or series number.
• Country of Manufacture: Enhancing traceability.
• Protection Levels: Numerical indicators for protection against hazardous parts, solid objects, and water ingress

These markings ensure users are informed about the device’s capabilities, limitations, and safety features.

In conclusion, compliance with IS 18830 ensures that cord extension sets are not only durable and reliable but also adhere to the highest safety standards. By providing protection against electrical and mechanical hazards, resistance to wear and environmental stress, and user-friendly features like clear markings, this standard enhances the safety, performance, and convenience of cord extension sets for both indoor and outdoor use.
