Irrigation plays a vital role in the Indian agriculture sector, and the quality of equipment used determines efficiency and output. IS 12786:1989, issued by the Bureau of Indian Standards (BIS), is a key specification that ensures the quality and performance of polyethylene pipes for irrigation laterals.
At Certificates.World, we help manufacturers and importers comply with BIS norms and navigate the certification process with ease. Here’s everything you need to know about IS 12786:1989 and its compliance requirements.
What is IS 12786:1989?
IS 12786:1989 is the Indian Standard for “Irrigation Equipment – Polyethylene Pipes for Irrigation Laterals.” It provides technical guidelines to ensure that pipes used in irrigation are safe, reliable, and durable.
Key Areas Covered:
- 
Scope: The standard focuses on pipes used in irrigation laterals—pipes that connect the main line to individual crop areas.
 - 
Material: It mandates the use of polyethylene, known for its strength, flexibility, and resistance to corrosion.
 - 
Dimensions: Includes detailed specifications on diameter, wall thickness, and length for compatibility with different systems.
 - 
Pipe Types: Covers LDPE and MDPE pipes, categorized by pressure ratings to suit various irrigation needs.
 - 
Color Coding: May include specific colors for identifying pipe types or pressure classes, simplifying field installation.
 
Mandatory Tests for Compliance
Products under IS 12786 must undergo several quality assurance tests:
- Dimensions Test
 - Internal Pressure Creep Rupture Test (Acceptance Test)
 - Reversion Test
 - Tensile Strength Test
 
These tests are critical to ensuring product performance and safety under operational conditions.
Why BIS Certification is Mandatory
If your product falls under the BIS Conformity Assessment Scheme, ISI marking becomes mandatory. Without this, manufacturers and importers are not permitted to market or distribute such products in India.
Failure to meet BIS standards can lead to license cancellation, penalties, and a ban on product distribution.
