TECHNICAL SPECIFICATION FOR METER BOARD FOR Service ...

1.0 SCOPE:
TECHNICAL SPECIFICATION FOR METER BOARD
FOR Service connections
1.1 This specification covers manufacture and supply of meter board with excellent
weather-ability so as to offer protection against harsh weather. The box shall be
anti-corrosive, dust proof, shock, vermin & waterproof, fire proof and UV
stabilized. The meter board shall not deform or melt when exposed to fire.
2.0 MATERIAL OF METER BOARD:
2.1 The meter board shall be made out of
2.1.1 Thermosetting plastic e.g. glassfibre reinforced polyester SMC (Sheet Moulding
Compound) as per S1 grade of IS: 13410, or Glass Reinforced Polyester Dough
Moulding Compounds as per Grade D1 of IS 13411, with flame retardant
properties and mechanical & corrosion resistant properties. The overall
dimensions of meter board shall be as per Annexure or as specified by the owner.
OR
2.1.2 Polycarbonate with UV stabilized & fire resistant properties.
2.2 All accessories of MS, like nuts, bolts, washers etc., shall be galvanized.
3.0 CONSTRUCTION
3.1 The meter board shall be single piece moulded.
3.2 Fixing arrangement:
The meter meter board shall have 4 nos. 6 mm dia holes for mounting the meter
board on a wall with suitable screws. The mounting arrangement shall be designed
in such a way that the board is securely held on to the wall with proper guides for
the screws.
3.3 Inlet and Outlet:
Suitable number of holes shall be provided in the meter board for cable/wire entry
as required. The size of the holes shall be suitably modified depending on the size
of the cable used for connections. Thickness of the meter board shall not be less
than 2.5 mm.
3.4 The meter board shall generally comply with the provision of IS14772 or IEC 695.
The meter board shall be suitable for outdoor/indoor application. The meter board
shall be with good workmanship.
3.5 The color of meter board shall be off white/admiral grey or as specified by the
owner.
3.6 Wherever required ribs of adequate thickness shall be provided beneath the face of
the board.
3.7 While moulding the meter boards upto 20 %( max) resin regrind may be used with
virgin material. The manufacturer shall declare the permissible regrind to be mixed

with virgin material & all type tests shall be conducted on items moulded with the
maximum permissible regrind.
3.8 It shall be possible to replace the switches/holders etc. without the need to remove
the meter board from the wall. Wherever required metallic inserts shall be provided
for fixing for fittings with screws. Screws fixing means shall be so designed that
they withstand the mechanical stresses during installation and normal use. Test for
this shall be carried out in line with clause 11.8 IS:14772
3.9 Marking:
The name of the manufacturer along with month & year of manufacture shall be
engraved/moulded on the bottom half of the meter board.
4.0 Sample Meter Board:
4.1 The manufacturer shall submit a sample meter board before commencement of bulk
production. The bulk production and supplies shall commence only after approval of
sample & type test reports by the owner.
5.0 Quality Control:
5.1 Type test report for UV stabilization test as per ASTMG 53/26/23 on the material
used for making the board shall be submitted for approval. Type test reports from
NABL accredited laboratory in accordance with clause 5 of IS: 14772 for the
following tests as per IS 14772 shall be submitted for approval. The type test reports
shall not be older than 5 years.
a) Marking
b) Dimensions
c) Construction - Test for screw fixing means as per clause 11.8 of IS: 14772
d) Resistance to ageing & to climatic condition as per clause 12.1.1 of IS: 14772
e) Resistance to humid condition as per clause 12.2 of IS: 14772
f) Mechanical strength as per clause 13.2 of IS: 14772
g) Resistance to heat as per clause 14.2 of IS: 14772
h) Resistance to abnormal heat and fire (Glow wire test) as per clause 15 of IS:
14772 at a temperature of 650 deg.C
i) Drop test- The meter board shall not get damaged or deformed when dropped
from a height of 2 meters on to concrete floor.
5.2 The owner may witness acceptance tests as per IS 14772 or any other applicable
standard. All tests shall be carried out on every batch of manufacturing. All test
records shall be maintained with proper correlation. IS 13360 ‘Plastics – Methods of
Testing’ shall be referred wherever required.
Following Acceptance tests shall be carried out in every lot:
a) Marking
b) Dimensions including thickness of material
c) Test for screw fixing means as per clause 11.8 of IS: 14772
d) Resistance to ageing to climatic condition as per clause 12.1.1 of IS: 14772
e) Resistance to humid condition as per clause 12.2 of IS: 14772

f) Mechanical strength as per clause 13.2 of IS: 14772
g) Resistance to heat as per clause 14.2 of IS: 14772
h) Resistance to abnormal heat and fire (Glow wire test) as per clause 15 of IS:
14772 at a temperature of 650 deg.C.
