Indian Standard

SPECIFICATION FOR FIRE-RESISTANT HYDRAULIC FLUIDS

PART I DILUTE EMULSIONS FOR POWERED SUPPORTS

0. FOREWORD

0.1 This Indian Standard ( Part 1 ) was adopted by the Indian Standards Institution on 12 April 1983, after the draft finalized by the Lubricants and Related Products Sectional Committee had been approved by the Petroleum, Coal and Related Products Division Council.

0.2 The use of fire resistant hydraulic fluids is increasing due to a growing awareness of the dangers inherent in using mineral oils for applications where there is a fire risk. There are four types of fire resistant hydraulic fluids namely dilute emulsions, invert emulsions; water glycols and synthetic fluids. This specification covers emulsifying oils suitable for adding water to make emulsions for use in powered supports and for other such hydraulic purposes. It gives basic require- ments for oils for these applications as well as provides guidance on their selection, storage and use.

0.3 Other parts of the standard published so far are as follows:

( Part 2 )-1983 I nvert emulsions ( water-in-oil ) type

( Part 3 )-1983 Water glycol type

( Part 4 )-1983 Phosphate esters type

0.4 Selection and use of the fire-resistant hydraulic fluids are covered in IS : 10531-1983* while determination of their fire-resistant characteristics is given in IS : 7895-19’75t.

0.5 In the preparation of this standard considerable assistance has been derived from NCB specification NO. 463/1970 publishedlby National Coal Board, U.K.

*Code of practice for selection and use of fire-resistant hydraulic fluids. TTests for fire-resistant characteristics of hydraulic fluids used in mining machinery.

3

IS : 10532 ( Part 1) - 1983

0.6 For the purpose of deciding whether a particular requirement of this standard is complied with, the fina value, observed or calculated, expressing the result of a test or analysis, shall be rounded of7 in accord- ance with IS : 2-I960*. 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 ( Part 1 ) prescribes the requirements and methods of sampling and test for fire resistant hydraulic fluids, dilute emulsions type, suitable for use in powered supports and for other simiIar hydraulic purposes.

2. GRADES

2.1 This standard covers two grades of oil for makin? emulsinns for use in hydraulic equipment but excluding hydraulic transmission units. These oils are designated as follows:

a) HF-A Grade 1 - Ordinary emul:ifying oil suitable for use with water varying between very soft and rather hard.

b) HF-A Grade 2 - Superior emulsifying oil suitable for very hard water.

2.1.1 The above classification is for guidance in selecting the correct emulsifying oil and does not necessarily imply that stability in service can be guaranteed with a11 waters of the hardness stated or the oil shall be unstable with waters of greater hardness ( see Note ).

NOTE - Experience and local knowledge may enable satisfactory judgement as to performance in service to be made on the basis of the requirements specified in 3, but in cases of doubt it may be necessary for a thermal stability test to be repeated with water actually to be used. Where the water is exceptionally corrosive it may also be advisable to repeat the test for rust preventing characteristics with the water actually to be used.

3. REQUIREMENTS

3.1 Requirements for Water

3.1.1 General - The water used for dilution shall meet the ‘folIowing requirements:

a) The water shall be free from suspended impurities and contamination;

*Rules for rounding off numerical values ( revised ).

4

IS : 10532 ( Part 1 ) - 1983

The PH of the water shall be within the range of 6 to 9 ( see IS : 3025-1964* );

Total hardness of water for mixing with Grade 1, ordinary emulsifying oil, shall not exceed a value of approximately 250 ppm ( as CaCOs ), though higher values may be acceptable in particular cases, where tests show the stability to be satisfactory ( see IS : 3025-1964* );

Total hardness of water for mixing with Grade 2 superior emulsifying oil, shall not exceed a value of approximately in 750 ppm ( as CaCOa ), though higher values may be acceptable in particular cases where tests show the stability to be satisfactory ( see IS : 3025-1964* ); and

Chloride and sulphate contents shall not exceed the values of approximately 200 mg/l of chloride ( Cl ) and 400 mg/l of sulphate ( SO4 ) though higher values may be acceptable in particular cases where tests show the stability and rust prevent- ing characteristics to be satisfactory ( see IS : 3025-1964* ).

b)

cl

3.2 Requirements for Oil

3.2.1 General - The oils used for making emulsions shall meet the following requirements:

a) The basic mineral oil, for example, an oil of the type known as spindle oil [ see IS : 493 ( Part II )-1981t 1, shall be free from deleterious impurities;

b) The soluble oil shall have ready self-emulsifying properties and the requisite stability and rust preventive characteristics;

c) The emulsion shall not deposit waxes in service; and

d) The water content of the emulsifying oil shall be stated by the manufacturer.

3.2.2 The material shall also comply with the requirements prescribed in Table 1 when tested according to the appropriate methods specified in co1 4 and 5 of the table.

3.2.3 Compatibility - If an emulsion made with oil complying with this specification is to be used in equipment operating on an emulsion made with a different oil, it is advisable to check for compatibility and to flush out the system and fill with new emulsion.

*Methods of sampling and test ( physical and chemical ) for water used in industry. +Specification for general purpose machinery and spindle oils : Part II Spindle oils

( jirst revision ) .

5

IS : 10532 ( Part I ) - 1983

3.2.4 Application - The dilute emulsion should be used at 5 percent oil content by volume in 5 parts of oil to 95 parts of water, for normal applications. The oil content should be checked regularly, say by using pocket refrectometer and should under no circumstances be allowed to fall below 3 percent. Working temperatures for these fluids are 5 to 55°C.

3.2.4.1 The emulsion should not be used in conjunction with any rubber or compound for which the volume change is outside the limits prescribed in Sl No. (vi) of Table 1.

4. PACKING AND MARKING

4.1 Packing - The material shall be packed in suitable containers as agreed to between the purchaser and the supplier. Galvanized drums/ barrels shall not be used for packing these fluids.

4.2 Marking - The containers shall be securely closed and marked with the name of manufacturer; name, type, grade and III~SS of the material; recognized trade-mark, if any; and with identification in code or otherwise to enable the lot of consignment or manufacture to be traced back; and the instruction for use.

4.2.1 The containers may also be marked w:th the IS1 Certification Mark.

NOTE - The use of the ISI Certification Mark is governed by the provisions of the Indian Standards Institution \ Certification Marks ) Act and the Rules and Regu- lations made thereunder. The ISI Mark on products covered by an Indian Standard conveys the assurance that they have been produced to comply with the require- ments of that standard under a well-defined system of inspection, testing and quality control which is devised and supervised by ISI and operated by the producer. ISI marked products are also continuously checked by IS1 for conformity to that standard as a further safeguard. Details of conditions, under which a licence for the use of the ISI Certification Mark may be granted to manufacturers or processors may be obtained from the Indian Standards Institution.

5. SAMPLING

5.1 Representative samples of the material shall be drawn as prescribed in IS : 1447-1966*.

6. STORAGE

6.1 The emulsifying oil shall be stored and handled strictly in accord- ance with the supplier’s instructions. The oil is a fire hazard before mixing with water and due precautions should be observed in this respect.

*Methods of sampling of petroleum and its products.
