Deepwell handpumps use different rubber components like seals, washers, and gaskets that play an important role in smooth water lifting and preventing leakage. These rubber parts are designed to handle constant movement, water exposure, and pressure, which make them essential for the proper working of hand pumps.
To make sure these rubber components are safe, durable, and perform well, the Bureau of Indian Standards provides BIS certification under IS 15500 (Part 7):2021. This certification confirms that the rubber parts meet required standards for quality, elasticity, strength, and resistance to wear and water conditions, ensuring reliable performance and longer service life.
What is IS 15500 (part 7):2021
This is an Indian standard that covers rubber components used in deep-well hand pumps, such as seals, gaskets, and washers. It is issued by the Bureau of Indian Standards to make sure these parts work properly and are:
- Flexible enough to maintain proper sealing during operation
- Strong enough to handle repeated movement and pressure
- Resistant to wear, water exposure, and environmental conditions
- Properly sized for correct fitting in handpump assemblies
- Tested for performance like leakage prevention and durability
Testing and Inspection Requirements – IS 15500 (Part 7):2021
To ensure proper sealing performance, and long service life of rubber components, the Bureau of Indian Standards (BIS) specifies strict testing and inspection requirements under the standard
Physical and Dimensional Tests
- Dimensions (R/S as applicable) – Ensures correct size, shape, and fitment of rubber components
- Critical Dimensions (R) – Checks essential design dimensions affecting performance
- Workmanship (R) – Ensures smooth finish, defect-free surface, and proper molding quality
- Hardness (R) – Verifies Shore hardness for required flexibility and strength
Raw Material and Component Tests
- Rubber Material Quality (S) – Ensures raw rubber meets specification requirements
- Consistency of Compounds (S) – Checks uniformity in rubber mix and additives
- Incoming Material Verification (S) – Ensures compliance of each consignment with standards
- Co-relation with Standard Rubber Grades (S) – Confirms suitability for potable water use conditions
Performance and Functional Tests
- Fitment Performance Check (R) – Ensures proper assembly and sealing in hand pump system
- Compression/Deformation Check (R) – Confirms resistance under working load conditions
- Functional Suitability Test (R) – Ensures rubber components perform effectively during pumping operation
Quality Assurance and Inspection Controls
- Workmanship Inspection (R) – Continuous monitoring of production quality
- Batch-wise Control Checks (R) – Each control unit (daily production batch) is verified
- Routine In-house Testing (R) – Mandatory for large-scale manufacturers for key parameters
- Subcontracted Verification (S) – Permitted for supporting material tests
Sampling Guidelines
- Sample Size: One rubber component per type
- Grouping Rule: Each type of hand pump rubber component must be tested separately
- Control Unit: Daily production batch of same type components
BIS certification process for Deepwell Handpump Rubber components
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 overall performance as per requirements.
- 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.

Marking Requirements & License Validity
When a manufacturer obtains the BIS license, the ISI mark for handpump rubber components must be applied clearly and permanently on the product or its packaging. In addition to the ISI Mark, other important details must also be provided on the product or packaging, as specified in the table below. This ensures the product meets all quality and safety standards.
| Requirement | Details |
|---|
| ISI Mark | Indicates that the product is BIS certified and conforms to standards |
| Standard Number | IS 15500 (PART 7) |
| CML Number | Certification Marks License (CML) number issued by BIS |
| Manufacturer Details | Name of manufacturer or registered trademark |
| Batch / Date | Batch number, heat number, or manufacturing date for traceability |
Note: Marking is typically applied using durable stamping, tagging, or permanent printing to ensure clear identification during handling, storage, and transportation, as per BIS marking requirements.
BIS license validity for Handpump Rubber components
After obtaining BIS certification for the product, the license is valid for a fixed period and must be maintained by following BIS rules and standards.
