BIS Certification for Glass-Fibre Reinforced Plastics (Grp) Pipes, Joints and Fittings for Use for Potable Water Supply IS 12709

GET BIS CERTIFICATION FOR GLASS-FIBRE REINFORCED PLASTICS (GRP) PIPES, JOINTS AND FITTINGS FOR USE FOR POTABLE WATER SUPPLY IS 12709:1994

GRP stands for Glass Reinforced Plastic. It is also called as fiberglass, composite plastic or FRP. It is strong, extremely light and highly versatile. GRP behaves differently from conventional thermoplastics that are used in everyday objects. This means that it has properties that are useful for a number of applications in many industries.

Potable water, also known as drinking water, comes from surface and ground sources and is treated to levels that that meet state and federal standards for consumption. Water from natural sources is treated for microorganisms, bacteria, toxic chemicals, viruses and fecal matter. Glass Reinforced Plastic is used for making pipes, joints and fittings for supply of potable drinking water.

BIS is a statutory institution established under the Bureau of Indian Standards Act,1986  to promote harmonious development of the activities of standardization, marking and quality certification of goods and attending to connected matters in the country.

Glass-fibre reinforced plastics (GRP) pipes, joints and fittings for use for potable water supply product has been specified in IS 12709:1994 by Bureau of Indian Standards.

SCOPE :

1.1 This specification covers requirements for materials, dimensions, classification, testing and type of joints of machine-made pipes with glass fiber reinforced thermosetting resin with or without aggregate filler having nominal diameter from 200mm to 3 000 mm for use at pressure up to 1 500 kPa for conveyance of potable water.

1.2 Provisions relating 10 fittings fabricated from GRP pipes or by moulding process have also been covered.
