Foot valves, reflux valves, and non-return valves are important flow control devices
used in water supply systems, pumping stations, irrigation networks, and industrial
pipelines. These valves help in controlling the direction of water flow and prevent
backflow, ensuring smooth and safe operation of pumping systems
To ensure the quality, safety, and performance of these valves, the Bureau of Indian
Standards (BIS) provides certification as per IS 10805:2022. The BIS certification
ensures that these valves meet the required standards of strength, leak-proof
performance, and proper functioning under working pressure conditions.
What is IS 10805:2022
This is the Indian Standard that specifies the requirements for foot valves, reflux valves,
and non-return valves used in water supply systems, pumping installations, irrigation
lines, and industrial fluid pipelines. This standard is issued by the Bureau of Indian.
Standards (BIS) to ensure that these valves perform safely and these are:
- Designed to allow smooth, controlled one-way flow of water or fluid
- Able to effectively prevent backflow and protect pumping systems
- Built to withstand working pressure without leakage or failure
- Durable enough for continuous operation in water and industrial applications
- Dimensionally accurate for proper installation and tight sealing
Testing and Inspection Requirements – IS 10805:2022
To ensure reliable flow control, leak-free performance, and long service life of foot
valves and bore valves used in agricultural pumping systems, the Bureau of Indian
Standards has defined strict testing and inspection requirements under the standard.
What are R and S?
- R (Required): Test must be carried out in the manufacturer’s in-house laboratory
- S (Subcontracting Allowed): Test can be done in a BIS-recognized or
NABL-accredited external laboratory.
Physical and Dimensional Tests
- Overall Dimensions (R) – Ensures correct size, shape, and dimensional
accuracy of valves
- Screwed End Dimensions (R) – Checks threading accuracy and fit as per IS
554

- General Component Fit (R) – Confirms proper assembly and movement of
valve parts.
Material and Coating Tests
- Raw Material Verification (S) – Ensures body and components meet declared
material specifications
- Coating Quality Test (S) – Checks protective coatings like paint for corrosion
resistance
- Paint Compliance Test (S)– Ensures coating materials conform to IS 341 and
IS 158
- Material Traceability Check (S) – Confirms proper documentation and
certification of incoming materials.
Performance and Functional Tests
- Seat Leakage Test (R) – Ensures zero or minimal leakage when valve is closed
- Housing Strength Test (R) – Verifies valve body can withstand hydraulic
pressure
- K-Value / Discharge Test (R) – Checks flow efficiency and hydraulic
performance
- Non-Return Function Test (R) – Confirms proper prevention of backflow.
Operational and Hydraulic Tests
- Hydraulic Pressure Test (R) – Ensures valve integrity under working pressure
- Flow Measurement Test (R) – Uses flowmeter or V-notch for discharge
evaluation
- Pressure Retention Test (R) – Confirms valve holds pressure without failure
- Functional Operation Test (R) – Verifies smooth opening and closing action
BIS certification process for foot valves
The BIS certification process ensures that the product meets the required standard for
proper and efficient operation as defined by the Bureau of Indian Standards (BIS). The
process includes the following steps:
- Online Registration: Manufacturers register on the BIS Manak Online Portal by submitting company
details, factory information, and product specifications. Foreign manufacturers
must appoint an Authorized Indian Representative (AIR) in India.
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories to evaluate efficient
operation and performance of valves.
- Application Submission: The application is submitted along with laboratory test reports, technical
documents, manufacturing process details, and factory information. Foreign
manufacturers must also provide AIR-related documents.
- Factory Inspection: BIS officials conduct an on-site inspection of the manufacturing unit to verify
production processes, quality control systems, safety measures, and compliance
with the standard.
- Grant of BIS: License
If all requirements are successfully met, BIS issues the certification license under
Scheme-I, allowing the manufacturer to produce and sell certified products.
- Use of ISI Mark: After certification approval, the manufacturer is permitted to use the ISI mark
along with a CM/L number on the product, confirming compliance with the
standard.
