Indian Standard

SPECIF ICATION FOR FABRICATED HIGM

DENSITY POLYETHYLENE ( H-DPE ) FI TTINGS

FOR POTABLE WATER SUPPLIES

PART I GENERAL REQUIREMENTS

0. FOREWORD

0.1 This Indian Standard ( Part I ) was adopted by the Indian StandardsInstitution on 17 January 1977, after the draft finalized by the Sanitary

Appliances and Water Fittings Sectional Committee had been approved

by the Civil Engineering Division Council.

0.2 The fabricated HDPE fittings are_ used for connection, by welding

process, to HDPE pipes covered by IS : 49X-1972*.

0.3 The requirements of fabricated HDPE fittings are covered in three

parts of this standard. This Part I of the series deals with the general

requirements applicable to all fabricated HDPE fittings. Specificrequirements of different types of fittings are covered in separate parts

of the standard.

0.4 For the purpose of deciding whether a particular requirement of this

standard is complied with, the final value, observed or calculated, express-

ing the result of a test or analysis, shall be rounded off in accordancewith IS : 2-1960t. 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 I ) covers general requirements for material,sizes, performance requirements, sampling and marking of all types of

fabricated HDPE fittings intended for connection to HDPE pipes covered

by IS : 49841972O for potable water supplies.

2. MATERIAL

2.1 The pipes used for the fabrication of HDPE fittings for potablewater supplies shall conform to IS : 4984-1972*.

3. SIZES OF FITTINGS

3.1 The sizes of the fittings shall be designated by their outsid?. diameters

at the free end. The outside diameters at the free end ai the fttings

shall correspond to the outside diameters of the pipes given in IS : 198.4

1972*.

4. -DIMENSIONS OF FlTTINGS

4.1 The outside diameters and corresponding wall thicknesses of fittingsat the free ends for weld shall comply with those given in Table 1 of

IS : 49g41972*.

4.2 The outside diameters shall be the average of two measurementstaken at right angles. The wall thickness shall be measured with a ball

ended micrometer. Resulting dimension shall be expressed to O-1 mm.

5. PERFORMANCE REQUIREMENTS

5.1 Hydraulic Proof Test - A fitting duly plugged, when subjectedto a hydraulic proof test of twice the recommended working pressure atambient temperature and for a period of one hour shall not show anysign of localized swelling, leakage or weeping_, and shall not burst during

the prescribed test duration.

6. SAMPLING

6.1 Lot - All fittings of the same size, same thickness, same length andfabricated in a single consignment, shall be grouped together to consti-

tute a lot.

6.2 The conformity of the lot to the requirements of this specificationshall be ascertained for each lot separately. The number of fittings tobe sampled from each lot shall depend on the size of the lot and shall bein accordance with co1 1 and 2 of Table 1.

6.2.1 These fittings shall be selected from the lot at random. In orderto ensure the randomness of selection, procedures given in IS : 4905-

.1968tmay be followed.

6.3 Number of Tests and Criteria for Conformity

6.3.1 Each fitting so selected shall be examined for requirements

given in 4 and 5. Any fitting failing in one or more of these requirementsshall be considered as defective. The lot shall be considered as confor-

ming to the requirements of this specification if the number of defectivefittings found in the sample does not exceed the corresponding acceptancenumber A given in co1 3 of Table 1._

6.3.2 The lot rejected according to 6.3.1 may be retested for character-

istics for which it has failed. For this purpose, the number of fittings

to be selected at random from the lot shall be according to co1 1 and 2

of Table 1. A fitting failing to satisfy the requirements of any of these

characteristics shall be considered as defective. The lot shall be deemed

to satisfy the requirements of the specification if the number of defective

fittings found in the sample does not exceed the corresponding acceptance

number B given in co1 4 of Table 1, otherwise the lot shall be rejected.7. MARKING

7.1 All fittings shall be clearly and indelibly marked at a prominentplace visible even after the installation of the fittings with the following

information:

a) The manufacturer’s name or identification mark, and

b) The size of the fitting and the appropriate class ( working

pressure ) of IS : 4984-1972* to which the pressure rating of the

fitting corresponds.

7.1.1 HDPE fittings conforming to specific requirements as prescribed

in the relevant parts of the standard may also be marked with the ISI

Certification Mark.

NOTE The use of the IS1 Certification Mark is governed by the provisions of the

Indian Standards Institution (Certification Marks) Act and the Ruler and Regu_

lations made thereunder. The IS1 hfark on products covered by an Indian Standardconveys the assurance that they have been produced to compl,y with the requirements

of that standard under a well-defined system of inspection, testing and quality

control which is devised and supervisedby IS1 and operated by the producer.

1.31marker! products are also continuously checked by 1% for conformity to that standardas a fur;iler safeguard. Details of conditions under which a liccnce for tbc use of

the ISI Certification Mark may be granted to manufacturers or processors, my bcobtained from the Indian Standards Institution.
