BIS Certification for Horizontal Centrifugal Self-Priming Pumps IS 8418

This applies to businesses involved in manufacturing, importing, or selling Horizontal Centrifugal Self-Priming Pumps. It ensures that the pumps comply with the requirements set by the BIS (Bureau of Indian Standards) under IS 8418 for quality, safety, and performance. These pumps are:

• Built for efficient and reliable water transfer
• Designed for automatic self-priming without manual effort
• Suitable for agricultural, industrial, and domestic use
• Tested to ensure consistent performance and durability
• Manufactured to meet standard safety and quality norms

• This standard ensures that these pumps are:
• Safe and efficient in operation without the need for manual priming
• Designed with proper construction and quality materials
• Capable of delivering consistent discharge and required head
• Durable and suitable for continuous usage in different conditions
• Resistant to wear, leakage, and mechanical failures
• Tested for performance, efficiency, and self-priming capability
• Uniform in design, dimensions, and overall manufacturing quality

• R (Required): Test must be conducted in the manufacturer’s in-house laboratory
• S (Subcontracting Allowed): Test can be conducted in a BIS-recognized or NABL-accredited external laboratory

• Material Compliance Check (S) – Ensures materials used conform to relevant Indian Standards as per Clause 6
• Material Verification Test (S) – Confirms use of standard-approved raw materials with valid test certificates

• General Construction Test (R) – Ensures compliance with general requirements as per IS 5120 (Clause 13.1)
• Hydrostatic Pressure Test (R) – Verifies strength and leakage resistance of pump casing (Clause 13.2)
• Impeller Balancing Test (S) – Ensures proper dynamic balancing of impeller for smooth operation (Clause 13.3)

• Design Feature Verification (S) – Checks compliance with design requirements (Clause 11.1 & 11.2)
• Performance Test (S) – Evaluates discharge, head, efficiency, and power consumption (Clause 12.2 / IS 11346)
• Priming Test (S) – Ensures pump can self-prime within specified time (Clause 12.3)

• Pump Operation Test (R) – Ensures smooth and efficient functioning under operating conditions
• Assembly & Fitment Check (R) – Verifies proper alignment and assembly of pump components
• Leakage & Sealing Test (R) – Ensures no leakage during operation

• Dimensional Verification (R) – Ensures pump dimensions match declared specifications
• Component Fit Test (R) – Confirms proper fitting of all mechanical parts

• Batch Inspection Test (R) – Ensures consistency across production batches
• Control Unit Verification (R) – Confirms compliance within defined production units
• Test Record Maintenance (R) – Ensures proper documentation of all inspections and test results

• Routine Performance Test (S) – Conducted periodically to ensure compliance with performance parameters
• Type Test (S) – Conducted during initial approval or design changes
• Failure Retesting Protocol (S) – In case of failure, subsequent pumps are tested until 5 consecutive samples pass

• Sampling Requirement – One pump sample is tested for Grant of Licence (GOL) and Change in Scope of Licence (CSoL)
• Marking & Labelling – Pumps must bear the BIS Standard Mark along with licence number
• Rejection Policy – Non-conforming products must be segregated and disposed of as per BIS Act, 2016

The BIS certification process ensures that Horizontal Centrifugal Self-Priming Pumps comply with the quality, safety, and performance requirements specified under IS 8418 by the Bureau of Indian Standards. The process includes the following steps:

• Online Registration: Manufacturers must register on the BIS Manak Online Portal by providing company details, manufacturing unit information, and complete product specifications.Foreign manufacturers are required to appoint an Authorized Indian Representative (AIR) based in India.
• Testing at BIS-Approved Laboratory: Product samples of the pumps are tested in BIS-approved laboratories to evaluate parameters such as hydraulic performance, self-priming capability, efficiency, mechanical strength, and durability as per the standard requirements.
• Application Submission: The manufacturer submits the BIS application along with test reports, technical specifications, product drawings, manufacturing process details, and quality control documents. Foreign applicants must also submit AIR-related documents.
• Factory Inspection: BIS officials conduct a detailed inspection of the manufacturing facility to verify the production process, in-house testing capabilities, quality control measures, and overall compliance with the standard.
• Grant of BIS License: After successful evaluation of the application, test results, and factory inspection, BIS grants the certification license under Scheme-I of BIS Conformity Assessment Regulations.
• Use of ISI Mark: Once certified, the manufacturer is authorized to use the ISI Mark along with a CM/L number on the pump, indicating that the product conforms to the standard and meets the required quality standards.
