Annex-A
GROUPING GUIDELINES

1) The Standard covers the following classification of emitting pipes for irrigation laterals:
a. Uniformity categories: Category A (higher uniformity of emission rates and smaller deviations from
nominal emission rate) and Category B (Lower uniformity of emission rates and greater deviations
from nominal emission rate)
b. Class of pipe (based on working pressure, from lower to higher): Class 1, 2, 3 & 4.
c. Type of Operation: Unregulated & Regulated
d. Nominal Size (based on outside diameter): 12, 16, 20 & 25 mm.

2) For considering grant of licence/inclusion, following grouping may be followed:

a. Uniformity categories: If sample of category A is drawn and tested, both categories A and B may be
considered for grant of licence/inclusion
b. Class of pipe (based on working pressure): Sample of each class of pipe which is intended to be
considered for grant of licence/inclusion shall be drawn and tested
c. Type of Operation: If sample of Regulated pipe is drawn and tested, both categories Unregulated &
Regulated may be considered for grant of licence/inclusion
d. Nominal Size (based on outside diameter): Sample of Pipes of any size preferably the largest size
may be drawn and tested for considering grant of licence/ inclusion for all sizes for which
manufacturing and testing facilities are available

3) The scope of Licence may be restricted based on the manufacturing and testing capabilities of the
manufacturer which shall be verified during next surveillance visit.

4) During operation of licence, samples of each variety covered in the licence shall be drawn by rotation.

SCHEME OF INSPECTION AND TESTING
FOR IRRIGATION EQUIPMENT – EMITTING PIPE SYSTEMS
ACCORDING TO IS 13488 : 2008

1. LABORATORY - A laboratory shall be maintained which shall be suitably equipped (as per the
requirement given in column 2 of Table 1) and staffed, where different tests given in the specification shall
be carried out in accordance with the methods given in the specification.

1.1 The manufacturer shall prepare a calibration plan for the test equipment.

2. TEST RECORDS –The manufacturer shall maintain test records for the tests carried out to establish
conformity.

3. PACKING AND MARKING – The Standard Mark as given in Schedule of the licence and
Licence Number (i.e. CM/L……….) shall be incorporated, and the packing and marking shall be done as per
the provisions of the Indian Standard, provided always that the product thus marked conforms to all the
requirement of the specification. In addition, details of BIS website shall be marked as follows: “For details
of BIS certification please visit www.bis.gov.in”

3.1 In addition, when the standard mark and other specified information are marked by screen printing, the
following colour coding scheme shall be followed:

Class of pipe Colour

Class 1 Red
Class 2 Blue
Class 3 Green
Class 4 Yellow

4. CONTROL UNIT - For the purpose of this scheme, pipes of the same designation (as per cl. 9.1 & 9.2 of
IS 13488: 2008), manufactured in an eight hour shift or part thereof, from the same machine, using the same
extrusion compound, shall constitute a control unit.

5. LEVELS OF CONTROL - The tests as indicated in column 1 of Table 1 and the levels of control in
column 3 of Table 1, shall be carried out on the whole production of the factory which is covered by this plan
and appropriate records maintained in accordance with paragraph 2 above.

5.1 All the production which conforms to the Indian Standards and covered by the licence should be marked
with Standard Mark.
5.2On the basis of tests and analysis reports, the decision regarding conformity or otherwise of a control unit
to a given requirement shall be made.

6. REJECTIONS – Disposal of non-conforming product shall be done in such a way so as to ensure that
there is no violation of provisions of BIS Act, 2016. Any rejected material which is potentially resalable shall
be deformed in such a manner that it cannot be used for any other purpose. A separate record shall be
maintained giving information relating to all such rejections/defective/substandard material of the production
not conforming to the requirements of the Specification and the method of its disposal. Such material shall in
no case be stored together with that conforming to the Specification. The Standard Mark (if already applied)
on rejected material should be defaced.

Note-1: Whether test equipment is required or sub-contracting is permitted in column 2 shall be decided by the Bureau
and shall be mandatory. Sub-contracting is permitted to a laboratory recognized by the Bureau or Government
laboratories empaneled by the Bureau.

Note-2: Levels of control given in column 3 are only recommendatory in nature. The manufacturer may
define the control unit/batch/lot and submit his own levels of control in column 3 with proper justification for
approval to BO Head.

Note-3: * Testing of different class of Pipes shall be made on rotational basis in order to test every class
designation (as per cl. 9.1 & 9.2) of Emitting pipe systems covered in the scope of licence in an operative
period of a year"
