Indian Standard SPECIFICATION FOR

FIRE EXTINGUISHER, CARBON DIOXIDE TYPE ( PORTABLE AND TROLLEY MOUNTED )

( Second Revision ) 0. FOREWORD

0.1 This Indian Standard ( Second Revision) was adopted by the Indian Standards Institution on 29 August 1986, after the draft finalized by the Fire Fighting Sectional Committee had been approved by the Civil Engineering Division Council.

0.2 One of important types of fire extinguishers used for putting out fire is the carbon dioxidetype which is suitable for fire fighting in oils, petroleum products and gas substances under pressure ( Classes B and C tires ) and also for fires involving electrical equipment. This standard was first published in 1964 and revised in 1976. This revision is being prepared so as to include higher capacity of fire extinguishers ( requir- ing the use of trolley ) besides up-dating the requirements in respect of the materials.

0.3 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

-

1. SCOPE

1.1 This standard covers the requirements regarding material, shape, construction and performance test of carbon dioxide fire extinguishers ( portable and trolley mounted ).

2. CAPACITY

2.1 The extinguisher shall be of the following capacities: a) Portable - 2 kg, 3 kg and 5 kg. b) Trolley Mounted - 7 kg, 9 kg and 22’5 kg.

9. SAMPLING AND CRITERIA FOR CONFORMITY

9.1 The details of sampling and criteria for conformity is given in Appendix A.

APPENDIX A,

( Clause 9.1 )

SAMPLING AND CRITERIA ‘FOR CONFORMITY

A-O. GENERAL

A-0.1 The risk involved in failure of a fire extinguisher to work, when needed, is extremely large. Fire extinguisher, therefore, ought to have a high degree of reliability for performance during the entire specified period of its service. It can be achieved only ,through adequate design and control of quality of all raw materials, component parts and fittings followed by process con:rol in all stages of manufacture and assembly.

A-l. SAMPLlNG

A-l.1 All fire extinguishers of the same type,, shape, design and capacity produced by the same manufacturer from similar materials

8

i 1

I!S : 2871- 1986

under almost identical conditions of manufacture shall be grouped together to constitute a lot.

1. A-l.2 Each lot shall be considered individually for the purpose of evaluation of quality in accordance with this specification.

A-1.2.1 The number of samples for testing to be taken at random from a lot_ and the criteria for conformity shall be as given in A-1.2.2.

A-1.2.2 From each lot, a number of samples as indicated below shall be selected at random.

Number of Items in the Lot

Sample Size

up to 25 3 26 to 50 5 51 to 100 8

101 and up to 200 8 percent

A-1.2.3 They shall be examined visually, as far as possible, in respect of requirement specified in 2 to 6 and 8 and in respect of leakage test

_ ( see 7.3 ).

A-1.2.4 All the samples tested shall pass all these tests for the lot to be declared to conform to these requirements.

A-1.2.5 One sample shall then be examined for discharge duration and one for intermittent operation and one of these for leakage.

A-1.2.6 In the absence of a test certificate from a manufacturer about conformity of various components ( see 3 ) and the quality of charge ( see 4 ) to the requirements of this specification, from a sample fire extinguisher one item each of all the component parts and fittings shall be taken separately and examined individually in respect of the relevant requirements laid down in this specification. The sample shall also meet the requirements regarding the quality of charge ( see 4 ).

For a product to be eligible for markingwith ECO logo, it shall also carry the 1S1Mark of BIS besides meeting additionaloptional environment friendly requirements. For this purpose, the StandardMark of BIS would be a single mark being a combination of the 1S1Mark andthe ECO logo. Requirements to be satisfied for a product to qualify for the BISStandard Mark for ECO friendliness being included in the relevant publishedstandards through an amendment. These requirements are optional;manufacturing units are free to opt for the 1S1Mark alone also.

The amendment is based on the Gazette Notification No. 160 dated 1 April 1999for Fire Extinguishers as environment friendly products published in the Gazetteof Government of India.
