BIS Certification Process for Countersunk Flat Head Screws
The certification process involves several steps to ensure compliance with IS 7485 (Part 1): 2018. Here’s an overview:
- Application Submission:
- Submit the BIS application form with details about the product, manufacturing processes, and testing facilities.
- Product Testing:
- Submit samples to a BIS-approved laboratory for testing against IS 7485 (Part 1): 2018 specifications. Tests focus on dimensions, mechanical properties, surface finish, and other critical parameters.
- Factory Inspection:
- BIS officials conduct an inspection of the manufacturing facility to verify compliance with the prescribed standards. This includes reviewing production processes and quality control systems.
- Documentation Submission:
- Provide a detailed Scheme of Inspection and Testing (SIT) outlining quality control measures and testing protocols.
- Grant of Certification:
- Upon successful completion of testing and factory inspection, BIS certification is granted, allowing the use of the ISI mark.
- Surveillance:
- BIS conducts periodic surveillance and random testing of certified products to ensure ongoing compliance.
List of Test Equipment for Compliance
To meet the requirements of IS 7485 (Part 1): 2018, manufacturers need access to the following test equipment:
- Micrometers and Vernier Calipers: For measuring dimensions such as head diameter, thread length, and recess depth.
- Torque Testing Machines: To assess the performance of the recess and head under specific torque conditions.
- Hardness Testers: For verifying material hardness to meet property class 4.8 specifications.
- Tensile Testing Machines: To evaluate the mechanical strength and load-bearing capacity of the screws.
- Salt Spray Test Chambers: For testing corrosion resistance of surface finishes.
- Thread Gauges: To check thread pitch, angle, and compatibility with corresponding components.
Availability of this equipment ensures that manufacturers can consistently produce screws that meet the BIS standard.
Scheme of Inspection and Testing (SIT)
The SIT is a vital document that outlines the quality control measures a manufacturer must implement to ensure compliance with IS 7485 (Part 1): 2018. Key components include:
- Raw Material Inspection:
- Test the chemical and mechanical properties of incoming materials to verify their suitability.
- In-Process Monitoring:
- Inspect critical parameters such as recess formation, thread rolling, and countersinking during production.
- Final Testing:
- Conduct thorough tests on finished screws, including dimensional checks, hardness testing, and corrosion resistance testing.
- Non-Conformance Management:
- Establish protocols for identifying, addressing, and preventing defects.
- Documentation and Record Keeping:
- Maintain comprehensive records of inspections, test results, and corrective actions to demonstrate compliance during audits.
