Injection-moulded PVC socket fittings are plumbing components made from polyvinyl
chloride (PVC) using a moulding process. These fittings are used to connect pipes in
water supply systems through solvent cement joints, ensuring a tight and leak-proof
connection. They are widely used in residential, commercial, and irrigation pipelines due
to their lightweight nature, corrosion resistance, and easy installation. These fittings play
an important role in maintaining smooth water flow and durable piping networks.
To ensure these fittings meet required quality and performance standards, the Bureau of
Indian Standards has defined guidelines under IS 7834 (Part 1): 1987. Manufacturers
must obtain BIS certification before supplying these products in the Indian market,
confirming that they comply with specified requirements for safe and reliable water
supply applications.
Overview of IS 7834 (Part 1): 1987 Standard
This is an Indian standard that specifies the general requirements for injection-moulded
PVC socket fittings used in water supply systems. It is issued by the Bureau of Indian
Standards to ensure these fittings are safe, reliable, and suitable for plumbing use.
The standard ensures that the product is:
- Made from proper PVC material for strength and durability
- Suitable for joining pipes using solvent cement joints without leakage
- Manufactured with correct dimensions and proper fit
- Resistant to corrosion and suitable for long-term water use
- Tested for important parameters like strength, dimensions, and overall quality

Benefit: BIS certification ensures product quality, leak-proof performance and builds
trust among buyers, helping in wider market acceptance.
BIS Testing & Quality Standards for PVC Solvent Cement Joint Fittings
To ensure proper quality and performance in water supply systems, the Bureau of
Indian Standards has defined testing and inspection requirements under IS 7834 (Part
1): 1987. These checks are carried out during manufacturing and quality control to
ensure fittings are safe, leak-proof, and durable.
What are R and S?
- R (Required): Tests conducted in the manufacturer’s in-house lab
- S (Subcontracting Allowed): Tests that can be done in BIS-approved or
NABL-accredited external labs
Raw Material Verification
- PVC Resin Check (R): Ensures the raw material meets required quality before
production
- Material Consistency (R): Confirms uniform composition for proper strength and
durability
Dimensional and Physical Checks
- Socket Size and Diameter (R): Verifies correct internal and external dimensions
- Wall Thickness Check (R): Ensures fittings have proper strength
- Out-of-Roundness Check (R):Confirms proper shape for tight pipe fitting
- Length and Taper Check (R): Ensures proper jointing and alignment
Performance Testing
- Stress Relief Test (R): Checks resistance to internal stress and deformation
- Hydrostatic Pressure Test (R): Ensures fittings can handle water pressure
without leakage or failure
Water and Safety Tests
- Effect on Water Test (S): Ensures fittings do not release harmful substances
into drinking water
- Opacity Test (S): Confirms the material prevents light penetration within limits
BIS License Process for Injection Moulded PVC fittings
To obtain BIS certification, manufacturers and other entities involved must follow the
standard approval process defined by the Bureau of Indian Standards to ensure
compliance with the standard.
- Online Registration: Register on the BIS Manak Online Portal with company details, factory address, and
product information. Foreign manufacturers must appoint an Authorized Indian
Representative (AIR) in India.
- Product Testing: The PVC socket fittings are tested in BIS-approved laboratories for dimensional
accuracy, hydrostatic pressure resistance, impact strength, joint integrity, and overall
quality performance as per the standard .
- Application Submission: Submit the application along with test reports, manufacturing details, and quality
documents. AIR documents are required for foreign applicants.
- Factory Inspection: BIS officials inspect the manufacturing unit to check the production process, equipment,
and quality control systems.
- License Approval: If all requirements are satisfied, BIS issues the license under Scheme-I for
manufacturing and selling the product in India.
- ISI Mark Usage: After approval, the manufacturer can use the ISI mark with a CM/L number on the
product, confirming compliance with the standard.
