BIS Certification for PVC-U Screen and Casing Pipes for Bore/Tubewell – IS 12818

The Bureau of Indian Standards (BIS) is the national body responsible for standardizing and quality-certifying products in India. When a product meets the required Indian Standard, it is granted a BIS license and allowed to bear the ISI mark, a symbol of trust, safety, and quality.

Indian Standard IS 12818 for PVC-U Screen and Casing Pipes

The Indian Standard for PVC-U screen and casing pipes designed for borewells and tubewells is IS 12818. This standard includes specifications, testing methods, dimensions, and performance criteria that these pipes must meet to ensure safety and durability in groundwater extraction. It ensures that the pipes maintain their structural integrity under soil pressure and varying water flow conditions.

IS 12818 classifies PVC-U casing and screen pipes into the following categories:

- CM (Casing Medium) – suitable for medium-depth borewells

- CS (Casing Shallow) – intended for shallow-depth borewells

- RS (Ribbed Screen) – designed for use as screens in tubewells

- PL (Plain Screen) – used as screens where slots are not required

Each category must adhere to specific requirements for material composition, mechanical properties, and physical dimensions.
