Venturi injectors are widely used across agriculture, irrigation, water treatment, chemical dosing, and fertigation systems. Since they directly impact water quality, chemical flow control, and system safety, the Bureau of Indian Standards (BIS) has brought several fluid-handling products under compliance requirements.
If you are manufacturing or importing Venturi injectors in India, understanding whether BIS certification applies and how to meet compliance is critical for market entry and legal sale.
This blog provides a complete overview of BIS certification requirements for Venturi Injectors, their regulatory status, testing requirements, processes, and documentation.
What is a Venturi Injector?
A Venturi injector is a device that uses the Venturi effect (pressure differential) to inject fertilisers, chemicals, or water-soluble liquids into a flowing water line without external power.
They are commonly used in:
- Agriculture & irrigation networks
- Drip & sprinkler systems
- Water treatment plants
- Chemical dosing applications
- Industrial fluid transfer systems
Do Venturi Injectors Require BIS Certification?
As of now, there is no dedicated IS (Indian Standard) specifically for Venturi Injectors under compulsory BIS registration.
However, compliance requirements may still apply depending on:
- Material of construction
- Application usage
- Associated equipment used with the injector
- Whether the product falls under any existing IS standard category
Cases Where BIS May Apply:
| Component / Product Type | Relevant IS Standard | Applicability |
|---|---|---|
| Plastic / HDPE parts used inside the injector | IS 4984, IS 12786 | If part of a pipeline network |
| PVC fittings & accessories | IS 10124 series | If injector is combined with PVC system |
| Drip irrigation system accessories | IS 13487 | If marketed as part of drip irrigation equipment |
| Metal components under pressure systems | IS 778, IS 15778 | Depending on pressure rating |
Why BIS Certification for Venturi Injector Matters to Manufacturers
Even if not under mandatory list, BIS certificate for venturi injector helps in:
1. Establishing reliability & credibility: Farmers, irrigation OEMs, and EPC contractors prefer BIS-tested components.
2. Ensuring material safety & performance durability
Testing ensures the injector’s:
- Flow rate accuracy
- Pressure handling
- Chemical compatibility
- Structural integrity
3. Eligibility for government tenders: Agriculture & irrigation tender documents often mandate BIS-compliant materials.
4. Competitive advantage
Certified products build trust in dealer and farmer networks.
Performance & Quality Parameters Checked During BIS Testing
Even for voluntary BIS certification, the following tests are common:
1. Dimensional & Visual Inspection
- Inlet/outlet diameter
- Thread accuracy
- Nozzle shape & taper dimensions
2. Pressure & Leak Test
- Hydrostatic pressure test
- Leakage under different flow rates
3. Material Tests
- HDPE / PP / PVC composition test
- Tensile strength
- UV resistance (for outdoor agriculture use)
4. Functional Tests
- Suction rate accuracy
- Uniformity of chemical injection
- Flow-pressure performance curve

Steps to obtain BIS Certification for Venturi Injector
Below we mentioned steps to obtain BIS certification for venturi Injector
Step 1: Identify the applicable standard
Evaluate whether the injector or its parts fall under any existing IS code.
Step 2: Factory Audit by BIS Officer
Validation of infrastructure, testing facility and quality management.
Step 3: Product testing in a BIS-accredited lab
Samples are sent for mandatory performance tests.
Step 4: Documentation and Submission
Preparing the application and uploading all the required documents.
Step 5: Grant of BIS License
If all the requirements are met, BIS issues ISI certification.
Timeline: 30-60 days depending on product type and trial period.

How Manufacturers Can Stay Compliant
- Use BIS-approved plastics/metals for parts
- Maintain proper QC during production
- Keep raw material test reports
- Ensure accuracy in suction & flow rate
- Maintain records for traceability
Conclusion
A Venturi injector may not currently be covered under the mandatory BIS CRS or ISI schemes, but compliance with BIS quality standards significantly improves product reliability, market acceptability and regulatory readiness.
Manufacturers and importers who actively conform their products to Indian standards stand to gain huge benefits – especially in agriculture, irrigation and EPC projects.
If Venturi injectors are included under mandatory certification in the future BIS notification, ready manufacturers will be the first to comply and dominate the market.
