Indian StandardSPECIFICATION FOR

URINOMETER

0 . F O R E W O R D

0.1 This Indian Standard was adopted by the Indian Standards Institutionon 20 April 1967, after the draft finalized by the Medical Glass Instrumentsand Appliances Sectional Committee had been approved by the ConsumerProducts Division Council.0 . 2 Preparation of standards for surgical instruments, medical equipment andapparatus, including medical glass instruments, has been taken up at theinstance of the Advisory Committee for Development of Medical Instruments,Equipment and Appliances of Government of India.0.3 Great need has been felt for the standardization of glass instruments usedin pathological work. This standard, which covers requirements forurinometers, is expected to help in providing uniform equipment to alllaboratories.0.4 Urinometer is a hydrometer intended for measuring relative density ofurine.0.5 This standard is one of a series of Indian Standards on pathologicalglass apparatus. Other standards in the series are:

IS : 3740-1966 Specification for tubes, glass, for pathological workIS : 374 1- 1966 Specification for tubes, sedimentationIS : 3742-1966 Specification for pipettes, dilution, for haemocyto-

metersIS : 4067-1967 Specification for tube, swab ( We&t type ), for throatIS : 4068-1967 Specification for ureometer, Doremus’ typeIS : 4087-1967 Specification for pipette for haemoglobinometer and

pipette, blood, biochemical

0.6 In the preparation of this standard, considerable assistance has beenderivedfromIND/SL/MED 5845(a) ‘Urinometer’ published by t$e.Ministryof Defence, Government of India.0.7 For the purpose of deciding whether a particular requirement of thisstandard is complied with, the final value, observed or calculated, expressingthe result of a test, shall be rounded off in accordance with 1s : 2-1960*.The number of significant places retained in the rounded off value should bethe same as that of the specified value in this standard.

*Rules for rounding off numerical values ( revised ).

IS : 4069 - 1967

1. SCOPE

1.1 This, standard lays down the requirements and methods of test forurinometers used in pathological work.

2. MATERIALS

2.1 The bulb and the stem of the urinometer and the cylinder shall be madefrom clear, heat-resistant glass ( for definitions see IS : 1382-1961” ). Theglass shall have sufficient resisting power against mechanical influences, inparticular against scratches, and against corrosion by common chemicals.

2.2 The weighting material shall be clean mercury, lead shots or othersuitable heavy material.

2.2.1 The lead shots shall be securely fixed in the lower bulb of theurinometer by means of cementing material so that there is no loosematerial in the bulb.

2.2.2 If mercury is used, it shall be confined in the lower bulb only.

2.2.3 The cementing material, when used, shall be such as not to softenat 80°C.

2.3 The graduated scale shall be on glazed white paper or any other suitablematerial.

3. SHAPE AND DIMENSIONS

3.1 The shape and dimensions of the urinometer and the graduated cylindershall be as given in Fig. 1 aad 2.

4. MANUFACTURE, WORKMANSHIP AND FINISH

4.1 The urinometer shall be well annealed, free from bubbles and, as far aspossible, free from striae, stones and other visible defects ( for definitions seeIS : 1382-1961* ). It shall be hermetically sealed and smoothly finished.The lower bulb shall be so made that the weighting material used inside itdoes not pass on to the other parts of the urinometer in whatever position thelatter is held. The bulb shall be so loaded that the urinometer alwaysfloats at all points within the range of the scale, with the steq.within l-5” ofthe vertical.

4.2 The axis of the stem shall be in line with the axis of the bulb.

4.3 The cylinder shall be well annealed, free from bubbles and, as far aspossible, free from striae, stones and other visible defects ( for definitions seeIS: 1382-1961* ). It shall have a wall of uniform thickness, smoothly

finished with the top edges well rounded off. It shall stand firmly withoutrocking. Its axis shall be vertical when standing with its base on a horizontaleven surface. It shall not topple over when placed on a surface inclined at10” to the horizontal. It shall pass the thermal shock test specified in 7.1.

5 . GRADUATIONS ON HYDROMETER

5.1 The scale and inscription shall be marked clearly in permanent blackink lines of uniform thickness. The lines shall show no evident irregularitiesin spacing. The scale shall be straight and without twist, and the graduationlines shall be at right angles to the axis of the urinometer. The thickness ofthe graduation lines shall be not less than 0.10 mm and not more than

0.20 m m .

5.2 The scale shall be calibrated at 27°C. It shall range from 1.000 to I-060and shall be divided into six major divisions by graduation lines, three-fourths

I the circumference of the stem. The major divisions shall be subdivided intohalves and tenths by lines half and one quarter the circumference of thestem respectively.

5.3 The longer graduation marks shall extend beyond the shorter ones on theleft of the scale only. On the right of the scale, the ends of all graduationmarks shall be vertically above one another. The numbers shall be on theleft of the scale, immediately above the graduation marks to which theyrelate and shall not touch or intersect any graduation mark. The number-ing shall be as given in Fig. 1.

6 . P E R F O R M A N C E

6.1 The urinometer shall float in an upright position and shall indicate thecorrect density of the liquid to within &O*OOl at 27°C when floated indistilled water.

7 . T E S T S

7.1 Thermal Shock Test - The graduated cylinder shall be first boiled inwater for 30 minutes and then plunged into water at about 20°C. There shallbe no chipping or cracking. I

8 . M A R K I N G

8.1 The urinometer and the cylinder shall be legibly and indelibly markedabove the graduations on the scale with the following:

a) Name of manufacturer, his initials or trade-mark; andb) Symbol ‘ 27°C ‘, to indicate that it is calibrated at 27°C.

IS : 4069 - 1967

8.2 Each urinometer and cylinder may also be marked with the IS1 Certifica-tion Mark.

NOTE - The use of the IS1 Certification Mark is governed by the provisions of theIndian Standards Institution ( Certification Marks ) Act, and the Rules and Regulationsmade thereunder. Presence of this mark on products covered by an Indian Standardconveys the assurance that they have been produced to comply with the requirementsof that standard, under a well-defined system of inspection, testing and quality controlduring production. This system, which is devised and supervised by IS1 and operatedby the producer, has the further safeguard that the products as actually marketed arecontinuously checked by IS1 for conformity to the standard. Details of conditions,under which a licence for the use of the IS1 Certification Mark may be granted tomanufacturers or processors, may be obtained from the Indian Standards Institution.
