IS 13585 (PART 1):2012

In this competitive scenario, it isn't easy to survive in the market without a standard quality and certified product. BIS license may also be required to sell products in the Indian market.

To get BIS certification and produce a standard quality product, the manufacturer must ensure that their product must follow the specified Indian standard.

Let's take a closer look at IS 13585 (Part 1): 2012 for Shunt power capacitors of the non - Self - Healing type for ac systems.

This Indian Standard (Part 1), which is identical to IEC 60931-1: 1996 issued by the International Electrotechnical Commission (IEC), was adopted by the Bureau of Indian Standards on the recommendation of the Power Capacitors Sectional Committee.

This standard cover 'Shunt power capacitors of the non-self-healing type for alternating current systems with rated voltages up to and including 1000 V - Part 1: General - Performance, testing and rating - Safety requirements - Guide for installation and operation.

The objective of this standard is to:

  • Develop uniform rules for performance, testing, and rating
  • Develop specific safety rules
  • Serve as a manual for installation and operation

This standard specifies the specifications for capacitors. The capacitor must meet the standard's quality, safety, and performance requirements.


The test is classified as:

Routine Test

  • Capacitance Measurement and output calculation
  • Measurement of the tangent of the loss angle of the capacitor
  • Voltage tests between terminals
  • Voltage tests between terminals and container
  • Test of the Internal Discharge Device
  • Sealing test

Type Test

  • Thermal stability test
  • Discharge test
  • Destruction test
  • Disconnecting test

Before delivery, every capacitor must have undergone routine testing by the manufacturer. Type tests are performed to ensure that the capacitor meets the specified characteristics and operation requirements outlined in this standard in terms of design, size, materials, and construction.

The Firm must declare the types of Capacitors that they intend to cover under the Licence. The scope of the Licence may be limited based on the Manufacturer's manufacturing and testing capabilities.

Labelling and Marking:

Labelling and marking shall be carried out in accordance with IS 13585 (Part 1):2012/ IEC 60931-1:1996. Each capacitor unit must mark with the information as specified in the standard.

The Standard Mark (ISI Mark) shall be marked on the product provided that the product so marked meets all specification requirements. The manufacturer must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark). The BIS issues a license based on a successful evaluation of the manufacturing infrastructure, quality control, testing capabilities, and manufacturing process.
