BIS Certification for Oil Pressure Stove (Offset Burner Type) – IS 10109:2018 Qualitance India

BIS Certification for Oil Pressure Stove (Offset Burner Type) – IS 10109:2018

Oil pressure stoves are appliances designed to burn pressurised kerosene for cooking and other heating applications. They are used in domestic kitchens, hostels, canteens, commercial establishments and field kitchens. Unlike ordinary wick-type stoves, an oil pressure stove operates by pressurising the fuel tank and supplying kerosene to the burner. The design, pressure-containing components, fuel supply arrangement and burner assembly must meet appropriate safety and performance requirements. In India, Oil Pressure Stoves of Offset Burner Type are covered under IS 10109:2018 – Oil Pressure Stoves – Offset Burner Type – Specification (Second Revision). This product is included in the BIS compulsory certification list under Scheme-I and is regulated under the Oil Pressure Stoves (Quality Control) Order, 1997. Manufacturers intending to manufacture or sell covered offset burner-type oil pressure stoves in India must obtain the applicable BIS licence and comply with the requirements of IS 10109:2018 before using the ISI Standard Mark. This article explains the product scope, applicable standard, safety and performance requirements, testing considerations, documentation and BIS certification process.

The BIS compendium on gas and oil-burning appliances describes offset burner-type pressure stoves as products generally available in capacities from 1.5 litres to 10 litres. The exact capacity and product varieties to be covered under a particular licence must be confirmed against the applicable standard and BIS assessment.

4. How Does an Offset Burner-Type Oil Pressure Stove Work?

An oil pressure stove uses pressurised kerosene as fuel. The basic operating arrangement consists of:
  1. A fuel container or tank.
  2. A pump for generating pressure inside the tank.
  3. A fuel feed pipe.
  4. A control or regulating arrangement.
  5. A burner assembly.
  6. A pressure-release arrangement.
  7. A stove body and supporting structure.
The user pumps air into the fuel tank to generate pressure. This pressure forces kerosene through the fuel feed arrangement towards the burner, where it is vaporised and burned to generate heat. In an offset burner design, the burner is positioned away from the fuel tank. This arrangement helps separate the burner and the fuel container. The pressure-containing tank and fuel delivery system require particular attention because leakage, excessive pressure or improper operation can create fire and safety hazards.

5. Technical and Safety Requirements Under IS 10109:2018

The standard specifies requirements relating to the construction, materials, pressure resistance, safety and performance of offset burner-type oil pressure stoves. Important areas of assessment include the following.

A. Construction and general requirements

The stove must have suitable construction and assembly to ensure safe operation. The design should provide:
  • Proper positioning of the burner and fuel container.
  • Secure connections between fuel system components.
  • Stable support and adequate clearance.
  • Suitable control and operating arrangements.
  • Components capable of withstanding normal operating conditions.

B. Fuel container

The fuel container is a critical pressure-containing component. Its construction must meet the applicable requirements for:
  • Material and construction.
  • Minimum sheet thickness.
  • Fuel capacity and arrangement.
  • Fuel feed pipe positioning.
  • Leakage prevention.
  • Pressure resistance.

C. Pump

The pump is used to generate pressure inside the fuel container. It must function correctly and maintain the pressure required for normal stove operation.

D. Pressure-release screw

The pressure-release arrangement allows pressure to be safely released from the fuel container. It must function properly and prevent unsafe pressure conditions during operation.

E. Filler cap and fuel leakage prevention

The filler cap and associated sealing arrangements must prevent fuel leakage during filling, handling and operation.

F. Burner assembly

The burner must be suitable for the intended fuel and operating pressure. Its construction and performance must ensure proper fuel delivery and combustion.

G. Taps and regulating arrangements

Fuel control components must function reliably and allow the user to control or stop the fuel supply as intended.

H. Stability

The stove must remain stable under the conditions specified by the standard. The BIS compendium identifies tilt stability up to 15° as an important feature of offset burner-type pressure stoves. The applicable test method and acceptance requirements must be confirmed from IS 10109:2018.

6. BIS Testing Requirements for IS 10109:2018

Testing is a critical part of BIS certification. The stove must be assessed against the applicable requirements of IS 10109:2018. The BIS Laboratory Information Management System (LIMS) identifies several important test areas for this standard.

Major tests and assessment parameters

Sr. No. Test / Parameter Purpose
1 Air pressure test Checks pressure resistance and leakage
2 Safety pressure test Evaluates safety under the prescribed pressure condition
3 Bursting pressure test Evaluates resistance to excessive pressure
4 Resistance to draught Assesses burner performance under draught conditions
5 Fuel creep test Checks unintended movement or leakage of fuel
6 Constructional requirements Verifies construction and component arrangements
7 Fuel container sheet thickness Checks material thickness
8 Fuel feed pipe height Verifies the prescribed pipe arrangement
9 Pump Checks pump operation
10 Pressure-release screw Checks pressure-release arrangement
11 Taps Checks fuel-control components
12 Burner assembly Evaluates burner construction and performance
13 Workmanship Checks quality of manufacture and assembly
14 Fuel consumption Evaluates fuel consumption
15 Thermal efficiency Evaluates heat utilisation and stove efficiency
The above list is based on the test parameters displayed in the BIS LIMS entry for IS 10109:2018 and the available BIS technical compendium. The complete test sequence, test conditions, apparatus, acceptance limits and reporting requirements must be taken from the current official edition of IS 10109:2018.

7. Pressure Testing Requirements

Pressure testing is one of the most important safety assessments for an oil pressure stove. Since the fuel container operates under pressure, the manufacturer must demonstrate that the product can withstand the specified pressure conditions without unsafe leakage or failure. The major pressure tests include:

7.1 Air pressure test

This test checks the pressure integrity of the fuel container and associated components under the prescribed test conditions.

7.2 Safety pressure test

The stove is evaluated at the specified safety pressure to assess whether it can withstand the required pressure condition.

7.3 Bursting pressure test

The bursting pressure test evaluates the resistance of the pressure-containing component to excessive pressure. These tests are important for verifying the structural integrity of the fuel container and reducing the risk of pressure-related failure. Important: The precise test pressures, holding periods, acceptance criteria and test setup must be taken from IS 10109:2018. They should not be inferred solely from the normal working pressure range.

8. Thermal Efficiency and Fuel Consumption

Apart from safety, the performance of an oil pressure stove is also important. Two major performance-related assessments include:

A. Fuel consumption

Fuel consumption testing evaluates the quantity of kerosene consumed during the specified operating conditions.

B. Thermal efficiency

Thermal efficiency measures how effectively the heat generated by the burning fuel is transferred for the intended cooking or heating application. The BIS compendium identifies minimum thermal efficiency figures of:
  • 55% for roarer-type burners
  • 58% for silencer-type burners
These figures are reported in the BIS compendium on gas and oil-burning appliances. Manufacturers should verify the applicable test method and acceptance provisions in IS 10109:2018 before using these figures as formal certification criteria.

9. Important Components and Raw Materials

Manufacturers should identify the materials and components used in the construction of the stove and maintain suitable incoming inspection arrangements. Typical components include:
  • Fuel container or tank
  • Burner assembly
  • Pump assembly
  • Fuel feed pipe
  • Filler cap
  • Pressure-release screw
  • Taps or control valves
  • Sealing washers and gaskets
  • Stove body and supporting frame
  • Handles and other accessories
The manufacturer's quality-control system should define:
  • Approved raw material specifications.
  • Supplier approval and evaluation.
  • Incoming material inspection.
  • Component inspection.
  • Assembly controls.
  • Final inspection and testing.
  • Batch identification and traceability.
Where a component is separately covered by another applicable Indian Standard or compulsory certification requirement, the manufacturer should verify the relevant compliance obligations independently.

10. BIS Sample Quantity for IS 10109:2018

The sample quantity is an important consideration when planning BIS certification. Important clarification: A current official BIS product manual specifically prescribing the sample quantity for IS 10109:2018 could not be verified in the available official sources reviewed for this article. Therefore, this article does not assign an unverified number of complete stoves as the mandatory BIS sample quantity. The sample quantity and sampling procedure should be confirmed with BIS or the concerned testing laboratory before arranging production samples. Manufacturers should prepare representative samples covering the intended product design and varieties, including relevant differences in:
  • Fuel container capacity.
  • Burner arrangement.
  • Construction.
  • Pressure-containing components.
  • Materials.
  • Fuel-control arrangements.
The laboratory may require additional components or test specimens depending on the applicable test programme. Do not confuse IS 10109 with IS 8808: IS 8808:2019 covers burners for oil pressure stoves and oil pressure heaters. Its product manual specifies two burners as the sample size for that separate product. This sample quantity does not establish the sample quantity for a complete oil pressure stove under IS 10109.

11. Manufacturing Facility Requirements

Manufacturers applying for BIS certification should establish appropriate manufacturing and quality-control arrangements. The manufacturing facility should have documented controls for:

A. Fabrication and forming

  • Fuel container fabrication.
