SCHEME OF TESTING AND INSPECTION

FOR CERTIFICATION OF STRUCTURED-WALL PLASTIC PIPING SYSTEMS

FOR NON-PRESSURE DRAINAGE AND SEWERAGE

Part 2 – Pipes and Fittings with non-smooth external surface, Type B ACCORDING TO IS 16098 (Part 2): 2013

1. LABORATORY A laboratory shall be maintained, which shall be suitably

equipped and staffed where different tests given in the specification shall be carried out in

accordance with the methods given in the specification.

2. TEST RECORDS All records of tests, inspection and calibration shall be kept in

suitable forms approved by the Bureau.

2.1 All testing apparatus/measuring instruments shall be periodically checked and

calibrated and records of such checks / calibration shall be maintained.

2.2 Copies of any records and other connected papers that may be required by the Bureau

shall be made available at any time on request.

3. QUALITY CONTROL - It is recommended that, as far as possible, Statistical

Quality Control (SQC) methods may be used for controlling the quality of the product during

production as envisaged in this Scheme (See IS 397 (Part I):1972, IS 397(Part 2):1985 and IS

397 (Part 3) : 1980]

3.1 In addition, efforts should be made to gradually introduce a Quality Management

System in accordance with IS /ISO 9001 as appropriate to the activities of the organization.

4. STANDARD MARK The Pipe shall carry the standard mark as given in column1

of the first schedule of the licence in the form of a transfix label. The mark may also be

applied by engraving in such a manner that it does not impair the strength of the pipe in any

way. Marking may also be done by screen printing, inkjet printing, laser printing.

5. OTHER MARKING In addition the following information shall be clearly marked

in indelible ink / paint on either end of each straight length of pipe or hot embossed on white

at intervals of not more than three metres with the following.:

a) The manufacturer’s name and its recognized trade mark, if any: b) Diameter series & Nominal size c) Stiffness Class d) Material , e) Lot no/ Batch number in code or otherwise which will enable to trace back the

date of production and the test records;

f) ISI Logo, IS Code no & License No………………(CM/L ………..) and g) Made in India, if required.

5.0 LEVELS OF CONTROL - The tests, as indicated in Table 1 attached and at the levels

of control specified therein, shall be carried out on the whole production of the factory which

is covered by this scheme and appropriate records and charts maintained in accordance with

paragraph 2.0 above. All the production which conforms to the Indian Standards and covered

by the license shall be marked with certification mark of the Bureau.

5.1 CONTROL UNIT - A Control unit is defined as a continuous extrusion run of one size

and class of pipe from one extrusion compound up to a maximum of 48 (forty eight) hours

duration.

5.2 RAW MATERIAL - Only those additives shall be added which are needed to facilitate

the manufacture of the pipe and the production of sound and durable pipes of good surface

finish, mechanical strength. None of these additions shall produce toxic hazard or impair the

strength of the pipes. Manufacturers own rework material (Complying with IS 16098 (Part 2),

Cl. 5.2) is permissible. The quantity of rework material used is to be declared by the

manufacturer. No other rework material shall be used.

5.3 In case of failure in any of the tests twice the no. of samples should be tested for that

requirement. If a further failure occurs, the entire lot shall not be marked.

5.4 In respect of all other clauses of the specification and at all stages of production, the

factory shall maintain appropriate controls and checks to ensure that their product conforms

to various requirements of the specification.

6.0 REJECTIONS - A separate record shall be maintained giving information relating to

the rejection of the production not conforming to the requirements of the specification and the

method of its disposal. Such material shall in no circumstances he stored together with that

conforming to the specification.

7.0. SAMPLES - The licensee shall supply, free of charge, the samples required in

accordance with the Bureau of Indian Standards (Certification) Regulations, 1988, as

subsequently amended, from the, factory or godowns. The Bureau shall pay for the samples

taken by it from the open market if applicable.

8.0 REPLACEMENT - Whenever a complaint is received soon after the goods with

Standard Marks have been purchased and used, and if there is adequate evidence that the

goods have not been misused, defective goods or their components are to be replaced or

repaired free of cost by the licensee in case the complaint is proved to be genuine and the

warranty period (where applicable) has not expired. The final authority to judge the

conformity of the product to the Indian Standard shall be with the Bureau. The firm shall

have own complaint investigation system as per IS 15400.

8.1 In the event of any damages caused by the goods bearing the Standard Mark, or Claim

being filed by the Consumers against BIS Standard Mark and not “Conforming to” the relevant Indian Standard, entire liability arising out of such non conforming product shall be

of licensee and BIS shall not in any way be responsible in such cases.

9.0 STOP MARKING- The marking of the product shall be stopped under intimation to

the Bureau if, at any time, there is some difficulty in maintaining the

conformity of their product to the specification, or the testing equipment goes out of order.

The marking may be resumed as soon as the defects are removed under intimation of Bureau.

9.1 The marking of the product shall be stopped immediately if directed to do so by

Bureau for any reason. The marking may then be resumed only after permission by the

Bureau. The information regarding resumption of markings shall also be sent to the Bureau.

10.0 PRODUCTION DATA The licensee shall send to BIS as per the enclosed

Proforma-1 to be authenticated by a Chartered Accountant, a statement of quantity produced,
