Elastomeric insulated cables play a critical role in modern electrical and industrial installations where flexibility, durability, and safety are essential. In India, these cables are governed by IS 9968 (Part 1):1988 with Amendments A1, A2, and A3:2016, which defines the specifications and testing requirements for elastomeric insulated cables for working voltages up to and including 1100 volts.
To ensure safety and compliance, manufacturers and project owners rely on an IS 9968 testing lab to verify that cables meet all prescribed electrical, mechanical, and environmental standards.
What Are Elastomeric Insulated Cables?
Elastomeric insulated cables are flexible cables insulated with rubber-based or synthetic elastomer compounds. These materials provide excellent resistance to heat, oil, moisture, abrasion, and mechanical stress. Because of these properties, such cables are widely used in:
- Industrial machinery
- Power distribution systems
- Construction sites
- Mining and heavy-duty equipment
- Portable electrical tools
When used in demanding environments, proper testing becomes essential to prevent failures and ensure long service life.
Overview of IS 9968 (Part 1):1988 + A1 + A2 + A3:2016
IS 9968 specifies the construction, materials, and performance requirements for elastomeric insulated cables. Part 1 of the standard focuses on cables designed for working voltages up to 1100 volts, covering both single-core and multi-core configurations.
The standard outlines:
- Type of elastomeric insulation and sheath
- Conductor construction requirements
- Electrical performance limits
- Mechanical strength and flexibility criteria
- Safety and quality benchmarks
Compliance with IS 9968 ensures that cables are safe for use in Indian electrical systems and industrial applications.
Importance of Testing Elastomeric Insulated Cables
Testing is a mandatory step before cables can be approved for supply or use. Elastomeric insulated cables testing for 1100 volts IS 9968 helps identify defects that may not be visible during visual inspection.
Testing ensures that:
- Electrical insulation performs under rated voltage
- Cables withstand mechanical stress during installation and use
- Insulation and sheath resist heat, oil, and environmental exposure
For accurate and certified results, testing must be conducted at an IS 9968 Part 1 elastomeric insulated cable testing laboratory with proper infrastructure and expertise.
Key Tests Conducted as per IS 9968
A certified elastomeric insulated cables testing laboratory as per IS 9968 typically performs the following tests:
- Conductor resistance test
- High voltage withstand test
- Insulation resistance test
- Tensile strength and elongation test
- Heat ageing test
- Abrasion and flexibility tests
These tests confirm that the cable can operate safely at up to 1100 volts without degradation.
Role of a Testing Laboratory in Noida
Noida has emerged as a major hub for electrical and industrial testing services. Choosing an elastomeric insulated cables testing laboratory in Noida offers faster turnaround time, technical expertise, and easy access for manufacturers across North India.
A professional IS 9968 elastomeric insulated cables testing lab in Noida provides:

Facilities such as a rubber elastomeric insulated cables testing lab in Noida and elastomeric insulated power cables testing lab in Noida help ensure that products meet regulatory and project-specific requirements.
Why IS 9968 Compliance Matters
Non-compliant cables can lead to insulation failure, short circuits, equipment damage, and serious safety hazards. When testing is conducted in an accredited IS 9968 testing lab, confidence in product quality is significantly improved.
Compliance with IS 9968:
- Enhances product credibility in the market
- Supports regulatory approvals and tenders
- Reduces risk of electrical accidents
- Ensures long-term operational reliability
Testing according to IS 9968 is not just a formality—it is a safeguard for both users and infrastructure.
Conclusion
Elastomeric insulated cables as per IS 9968 (Part 1) are designed to deliver reliable performance in applications up to 1100 volts, even under harsh conditions. However, their safety and durability depend heavily on proper testing and standard compliance.
By choosing a trusted elastomeric insulated cables testing laboratory as per IS 9968, especially an experienced IS 9968 elastomeric insulated cables testing lab in Noida, manufacturers and users can ensure quality, safety, and regulatory conformity. Rigorous testing today prevents costly failures tomorrow and supports a safer electrical ecosystem.
