Notification
Thermocouple Compensating Cables are regulated under the Cables (Quality Control) Order, 2020, issued via S.O. 280(E) on 21 January 2020 by the Ministry of Commerce & Industry (DPIIT) under the BIS Act, 2016. Compliance with IS 8784:1987 is mandatory for all manufacture, import, and sale in India.
Overview
Thermocouple compensating cables are used to connect thermocouples to measuring instruments. They are designed with conductors of specific compositions to match the thermoelectric characteristics of the thermocouple, ensuring accurate temperature readings over extended distances.
Objective & Scope
The standard ensures dimensional accuracy, electrical resistance control, mechanical strength, and temperature coefficient stability, thus maintaining fidelity of measurement signals in industrial applications.
Products Covered
Compensating cables made of matched alloy conductors for use with thermocouples, designed for accurate transmission of thermoelectric signals in temperature measurement systems. Supplied with insulation and sheathing suitable for industrial, laboratory, and field environments.
Exemptions Provided
Products meant exclusively for export are exempt from BIS certification.
Industries Impacted
Cable manufacturers, temperature measurement system suppliers, petrochemical plants, steel manufacturing, power generation, process control industries, and research facilities.
Mandatory Compliance Requirements
From 1 August 2020, all such cables must:
- Conform to IS 8784:1987
- Be BIS-certified under Scheme-I
- Carry the ISI mark on cable and packaging
Enforcement Timeline
Effective 1 August 2020 for all manufacturers, importers, and sellers.
Next Steps for Stakeholders
- Conduct mandatory testing for electrical, thermal, and mechanical parameters in BIS-approved labs
- Prepare QMS and technical documentation
- Apply for BIS licence and secure approval before sale
- Ensure ISI marking before product release
Legal Provisions, Enforcement & Penalties
Regulated under the BIS Act, 2016 and enforced by the Bureau of Indian Standards.
Non-compliance may result in:
- Seizure of stock
- Suspension or cancellation of BIS license
- Fines and/or imprisonment up to 2 years, or both
Conclusion
Since 1 August 2020, all thermocouple compensating cables sold in India must comply with IS 8784:1987, be BIS-certified, and bear the ISI mark. This ensures consistent accuracy in temperature measurement and aligns with safety and quality norms.
