IS 15778:2007

In this competitive scenario, it isn't easy to survive in the market without a standard quality and certified product. BIS license may also be required to sell products in the Indian market.

To get BIS certification and produce a standard quality product, the manufacturer must ensure that their product must follow the specified Indian standard.
Let's take a closer look at IS 15778:2007 for CPVC Pipes.

Chlorinated polyvinyl chloride (CPCV) pipes for potable hot and cold water distribution supplies are covered under IS 15778:2007. The BIS adopted this Indian Standard after the Civil Engineering Division Council approved the draft finalized by the Plastic Piping Systems Sectional Committee.

This standard defines the requirements, test methods, and marking methods for chlorinated polyvinyl chloride plastic pipes for hot and cold water distribution supplies, manufactured in three standard dimension ratios, and intended for water service up to and including 82°C.

The pipes shall be classified by pressure rating (working pressure) at 27°C and 82°C as follows:

Pressure class Working pressure in MPa
SDR 27degree C 82 degree C
Class 1 11 2.76 0.68
Class 2 13.5 2.18 0.55
Class 3 17 1.73 0.42

The material from which the pipe is made shall be primarily chlorinated polyvinyl chloride. Only those additives are necessary to facilitate pipe manufacturing, and the production of sound and durable pipe with good surface finish, mechanical strength, and opacity under use conditions may be added.

The pipe shall be subjected to the following test:

  1. Type test
  2. Acceptance test
  3. Opacity test
  4. Reversion test
  5. Vicat Softening Temperature
  6. Hydrostatic pressure test
  7. Resistance to External Blow
  8. Flattening test

All pipes must be clearly and indelibly marked with the Manufacturer's name or trademark, outside diameter, pipe and pressure rating class, and batch number as per specification.

The Standard Mark (ISI Mark) may also be applied to each pipe. The Manufacturer must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark). The Bureau grants a license based on a successful assessment of manufacturing infrastructure, production process, and quality control and testing capabilities during a visit to its manufacturing premises.
