Gas appliances and all the relevant parts like regulators must adhere to established safety standards, particularly in cases involving flammable fuels such as LPG (Liquefied Petroleum Gas). A low-pressure regulator is one such mandatory part that is used in enormous numbers in household environments, commercial buildings, and industries. A gas regulator is a device that helps control the flow and pressure of gas. It takes gas from a high-pressure source, like a gas cylinder or pipeline, and lowers the pressure to a safe and usable level. This way, the gas can be used safely in appliances like stoves, heaters, or industrial machines. The regulator keeps the pressure steady so the gas supply stays safe and smooth. 

To ensure that such regulators are safe, the Bureau of Indian Standards (BIS) issues a certificate called BIS certificate for regulators under IS 9798:2013. This Indian Standard defines the standard for Low Pressure Regulators to be employed in order to enhance safety, quality, and efficiency levels. They aim to reduce the high pressure of the LPG gas from the cylinder to a safer, lower pressure in such a way that the consumption of the gas via stoves, heaters, etc., is safe. By complying with IS 9798:2013 and getting BIS certificate for regulators, manufacturers reassure customers that their products are safe, reliable, and can operate in varied conditions. 

Overview: IS 9798:2013 – Low Pressure LPG Regulators

The IS 9798:2013 standard provides comprehensive technical and performance requirements for two-stage or single-stage low-pressure regulators. The regulators are fitted in the vapor space of LPG mixtures and are designed to provide an outlet pressure of a maximum of 4.903 kN/m² (or 500 mm water column). Precedence in the standard is given to some of the concerns as detailed below:

• Requirements for design and construction
• Specifications for materials
• Pressure and resistance to control
• Resistance to deterioration
• With different LPG blends
• Test procedures under different simulated conditions

By following the specifications of IS 9798:2013, regulators reduce the possibility of overpressure, gas leakage, and operation failure and thus improve overall safety to end-users.

Key Details at a Glance of BIS Certificate for Regulators

Some of the key details of the BIS certificate for regulators are discussed below: 

• Product Name: Low Pressure Regulators for use with LPG Mixtures
• Applicable Standard: IS 9798:2013
• Certification Scheme: ISI Mark Scheme (Scheme-I, Schedule-2)
• Compliance Requirement: Mandatory
• Usage Scope: Domestic, commercial, and industrial LPG systems
• Outlet Pressure Limit: 4.903 kN/m² (or 500 mm WC)

Importance of BIS Certificate for LPG Regulators?

A BIS certificate for regulators is not just compliance, it's a promise and quality indicator. Low-pressure regulators are handling an extremely flammable product such as LPG, and thus, even minor defects can amount to a big risk. BIS certificate are important because of the following reasons: 

• Guarantee of Safety: BIS-tested, certified regulators are safer to use by domestic as well as business organizations.
• Regulatory Compliance: Indian legislation requires a BIS certificate for regulators under the ISI mark scheme.
• Consumer Confidence: The consumer will be more confident to trust and buy products with the BIS mark which can be applied only after getting a BIS certificate for regulators.
• Market Access: Local and overseas manufacturers are forced by this certification to sell their products legally in India.
• Brand Reputation: BIS-certified products enhance brand value as well as create the reputation and commitment of the manufacturer towards quality and safety.

Procedure to Get BIS Certificate for Regulators 

In order to get the BIS Certificate for regulators one needs to follow the step by step process given below: 

Application Filing for BIS Certificate for Regulators

Once the documents are prepared, the application for a BIS certificate for regulators has to be submitted by the manufacturer in the BIS portal. Domestic manufacturers and foreign manufacturers have varying procedures for filing the applications. Foreign manufacturers are also requested to nominate an Authorized Indian Representative (AIR) to whom the BIS will address. Application with specific mention of the nature of the product, standard code (IS 9798:2013), information of the manufacturing unit, and sample of the product as intended.

BIS Audit

BIS, upon receiving the application, conducts a factory audit in an effort to confirm whether the product is being produced to the necessary standards or not. BIS officials confirm the following things: 

• Confirm the manufacturing process.
• Confirm inspection of quality control equipment.
• Confirm the internal test procedure being adopted.
• Confirm whether the production unit is BIS compliant.

All these processes ensure that manufacturers are not only substituting conforming specimens but also have mechanisms to produce safe regulators regularly.

Product Sample Test

An official sample of the regulator is collected by BIS officials during the following tests:

• Pressure regulation tests
• Material strength
• Leak resistance
• Long-term performance which is related to the different functions
• Safety under stress and high-temperature conditions

The sample product is eligible for BIS certificate for regulators by the manufacturer as long as it complies with all the parameters stated.

BIS License Granted

BIS grants the BIS certificate for regulators following a successful factory audit and satisfactory test reports. The ISI Mark (BIS Standard Mark) can now be utilized by the manufacturer in the event of low-pressure LPG regulators. The licence is perpetual and has to also periodically get renewed on the basis of continuous conformity and surveillance audits.

Documents Required for the BIS Certificate for Regulators 

The procedure for BIS certificate for regulators begins with collecting and preparing all the documents required by BIS. some of the key documents required for the BIS certificate for regulators are given below: 

• Application form (Form VI)
• Business registration proof (e.g., GST, MSME, or Company Incorporation)
• Test report from BIS-recognized lab (not older than 90 days)
• Factory license and location detail
• Manufacturing process flow chart
• List of machinery and equipment
• Quality control parameters and test facilities
• Authorization letter (if agent/consultant is applying)
• Trademark registration (if applicable
• Undertaking/affidavit (as required by BIS)
• Proof of Indian representative (for foreign manufacturers)

The correct documents are to be provided, as incorrect or incomplete information will cause delay or rejection of the application during the processing of the application.

Timeline for BIS Certificate for Regulators

The duration of BIS certificate for regulators differs based on whether the applicant company is an Indian company or a foreign company:

• Indian Manufacturers: Usually 30 working days with proper documents and test reports submitted.
• Foreign Manufacturers: Since additional procedures like AIR appointment and customs clearance for sample testing are involved, it can take up to 180 days.

BIS certificate for regulators as per IS 9798:2013 is mandatory for safe and efficient use with LPG mixtures. For any manufacturer keen to establish an outlet in the Indian market or an end-user who wants the quality of products, the BIS mark guarantees the same. It reduces the chances of accidents and defaults of law and enhances their brand credibility. If you are a manufacturer or an importer looking to obtain certification, it is simpler and faster if you engage a compliance expert like us. Our knowledge and experience with BIS procedures guide you through documentation until the ultimate grant of license.
