ISO 15636:2003

Back-up pads for vulcanized fibre discs

ISO 15636:2003 specifies the design and dimensions of back-up pads intended for the fixing or clamping of vulcanized fibre discs in accordance with ISO 16057, or comparable grinding tools on hand-held grinding machines, e.g. angle grinders. The connecting dimensions of support discs and clamping units are matched for spindle ends with the common practice of this kind of hand-held machine.

Plateaux d'appui pour disques en fibres vulcanisées

L'ISO 15636:2003 spécifie la conception et les dimensions des plateaux d'appui destinés à la fixation ou au serrage de disques en fibres vulcanisées conformes à l'ISO 16057, ou d'outils de meulage pour meules portatives comparables, par exemple meules d'angle. Les dimensions de raccordement des plateaux d'appui et des unités de serrage sont conformes aux terminaisons de broche compte tenu de la pratique commune de ce type de machines portatives.

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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15636 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 5, Grinding
wheels and abrasives.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
L'attention est appelée sur le fait que certains des éléments du présent document peuvent faire l'objet de
