ISO 15636:2003

Overview

ISO 15636:2003 establishes standardized requirements for the design and dimensions of back-up pads used with vulcanized fibre discs on hand-held grinding machines, such as angle grinders. These back-up pads are essential for securely attaching or clamping fibre discs and comparable abrasive tools, ensuring both performance and operator safety. The standard ensures the compatibility of connecting dimensions between support discs, clamping units, and machine spindle ends, in alignment with widely accepted industry practices. This harmonization fosters greater reliability and interchangeability in industrial and commercial grinding applications.

Key Topics

• Scope of Application
  ISO 15636:2003 applies specifically to back-up pads for vulcanized fibre discs as defined in ISO 16057 and similar grinding tools on portable grinding machines.

• Design and Dimensions

  • Specifies the shape, form, and key dimensions of back-up pads and associated clamping nuts.
  • Ensures that connecting threads and diameters are compatible with standard spindle ends found on most angle grinders and hand-held grinding machines.
  • Provides dimension tables and guidelines that manufacturers and users should follow for proper matching of components.

• Material Requirements

  • Defines that the back-up pad should be made from a polymer as chosen by the manufacturer.
  • The clamping nut material is also at the manufacturer's discretion, allowing flexibility while maintaining the core design and safety requirements.

• Designation and Marking

  • Provides a standardized way to designate back-up pads, including references to size, thread specifications, and maximum permissible speed.
  • Mandates clear marking on each back-up pad, identifying the manufacturer or supplier and indicating the maximum speed of rotation to ensure safe use.

Applications

ISO 15636:2003 delivers practical benefits for a range of stakeholders in the abrasives and metalworking industries:

• Manufacturers

  • Ensures that back-up pads and fibre discs are consistently compatible with a wide range of hand-held grinding machines worldwide.
  • Simplifies design and production processes while meeting global safety and interoperability standards.

• Distributors and Suppliers

  • Facilitates inventory management by standardizing product specifications, making it easier to source and supply compatible back-up pads for various tools.

• End Users

  • Improves worker safety and operational efficiency by ensuring that back-up pads fit securely and operate reliably at prescribed speeds.
  • Reduces the risk of improper installation, disc slippage, or mechanical failure during grinding, sanding, or finishing operations.

• Regulators and Compliance Officers

  • Provides a clear benchmarking framework for inspecting and certifying the safety and performance of portable abrasive tools and accessories.

Related Standards

To ensure full compliance and optimal application, ISO 15636:2003 should be considered alongside related standards, including:

• ISO 16057

  • Coated abrasives - Vulcanized fibre discs.
  • Defines requirements for the fibre discs themselves, ensuring they match back-up pad specifications.

• ISO/TC 29 (Small tools), Subcommittee SC 5 (Grinding wheels and abrasives)

  • Oversees harmonization activities for backup pads, grinding wheels, and associated equipment.

Using ISO 15636:2003 in conjunction with these related standards guarantees compatibility, safety, and global best practices in the production, selection, and use of back-up pads and vulcanized fibre discs in industrial grinding processes.
