- BIS For AC motor capacitors is a requirement under IS 2993.
- This applies to capacitors with a rating of up to 660 V, 50/60 Hz, that have paper, plastic film, and/or mixed dielectrics.
- All manufacturers must be registered and must have sufficient production set-up, quality systems, and BIS-approved laboratory facilities for testing.
- Foreign manufacturers must provide an Indian representative to apply under FMCS regulations.
- The certification process is as follows: application → factory audit → sample testing → grant of licence.
- The ISI mark can only be used for certified Capacitors, and must indicate specific product details (voltage, capacitance, frequency, and manufacturer’s name).
Introduction
BIS Certified A.C. Motor Capacitors are applicable in various applications such as home appliances, industrial equipment or commercial machinery. It will help improve the performance and efficiency of motors in mechanical applications such as ceiling fans, pumps, compressors, and washing machines. An AC motor cannot run consistently and reliably without the proper capacitor. The Bureau of Indian Standards (BIS) has mandated A.C. Motor Capacitors to have a BIS Certification under IS 2993 to ensure safety and quality for all manufacturers and dealers.
What is BIS For AC Motor Capacitors?
Bureau of Indian Standards (BIS) certification of A.C. Motor Capacitors is provided to ensure that capacitors meet the quality, safety, and performance requirements of IS 2993. As A.C. Motor Capacitors are essential components of several consumer products, such as fans, pumps, compressors, and washing machines, the reliability of these capacitors is of utmost importance to consumer safety. BIS Certification permits manufacturers to mark the capacitor with the ISI mark striking equal consumer acceptance that the capacitor has been tested to comply with the laws of Indian Jurisprudence.
Understanding IS 2993 – A.C Motor Capacitor
- IS 2993:1998 – Indian Standard for A.C. Motor Capacitors.
- Outlines safety, performance and quality requirements.
- Specifies capacitors for single-phase motors (including fans, pumps and appliances.
- Specifies the capacitors rated voltage, capacitance, tolerance, insulation resistance and endurance.
- Includes electrical tests (capacitance, dielectric strength, power factor).
- Includes electrical tests (capacitance test, dielectric strength test, power factor test).
- Mandates ISI Marking with manufacturer and rating details.
- Ensures safe and reliable motor operation.
- Compliance is mandatory for BIS Certification.
Types of A.C Motor Capacitors
Various types of A.C Motor Capacitors that are often used for electrical motors:
Run Capacitors
- These capacitors are connected continuously in the motor.
- The capacitor assists in establishing a phase shift to produce a rotating magnetic field in the motor.
- The run capacitor increases the running efficiency and power factor of the motor during long-term operation.
Start Capacitors
- This type of capacitor is connected only during the startup of the motor.
- The capacitor provides the motor with the high starting torque necessary to provide or develop the mechanical load.
- Once the rotor has achieved a pre-set speed, the capacitor will disconnect itself automatically.
- Start capacitors are usually electrolytic in nature and not designed to run in a continuous application.
Dual-Run (or Permanent Split Capacitor) Capacitors
- These capacitors have the functions of both start and run in a combination capacitor.
- This type of capacitor can be used in motors that require high starting torque and a good running efficiency.
Motor-Run Capacitors with AC Rating
- This capacitor is referenced for continuous AC voltage and is used to operate the motor as designed if rated.
- This capacitor rating is specific for long term continuing operation and withstand higher temperature from use.
Polyester Film Capacitors (used in motors)
- The type of capacitor is non-polarized and reliable for general use in an AC motor.
- This type is a film metal capacitor and designed to handle the heat & electrical stress.
Who needs BIS Certification for A.C. Motor Capacitors?
The BIS certification (Bureau of Indian Standards certification) is required for many electronic and electrical equipment, and A.C. Motor Capacitors are among those.
- Every A.C motor capacitors manufacturer (domestic or international) is required to obtain BIS certification (ISI Mark Licence) in order to sell their products in India, which is applied through the “BIS certification requirements”
- Any A.C. Motor Capacitors importer, must confirm that they have verification of certification to sell the product, either from the overseas manufacturer that complied with their BIS certification requirements if applicable, or that he or she are in possession of the imported product and it has received BIS certification to allow for selling the product in India.
- Trade distributors and manufacturers do not apply for obtaining BIS certification, but they may sell products made at a factory and the products received BIS certification.
Why is BIS Certification compulsory for A.C Motor Capacitors?
BIS Certification is compulsory for A.C. Motor Capacitors in India for many crucial reasons.
Legal Requirement
- The Government of India has mandated BIS certification for A.C. Motor Capacitors under Compulsory Registration Scheme / IS 2993:1998.
- It is illegal for anyone to sell or import capacitors without BIS approval.
Consumer Safety
As a capacitor operates under high voltage, poor-quality capacitors can result in:
- Electrical shocks
- Fire hazards
- Motor damage
BIS-certified capacitors ensure safety in electrical operation.
Quality Assurance
BIS certification ensures that the capacitor meets requirements under IS 2993:1998 requirements relating to:
- Capacitance
- Insulation resistance
- Dielectric strength
- Operation during temperature and voltage stresses
Trustworthiness and Performance
- BIS-certified capacitors ensure correct motor performance, longer capacitor life and reduced breakdowns.
Consumer Trust and Market Penetration
- Capacitors with an ISI mark are well trusted by buyers, including those from government tenders and other industries.
- May help the capacitor manufacturers compete within the domestic and export markets.
Prevent Poor Imports
- BIS certification prevents unsafe or low-quality capacitors from entering the Indian market.
