ISO 16057:2002

Overview

ISO 16057:2002 is an international standard published by the International Organization for Standardization (ISO) that specifies the nominal dimensions of vulcanized fibre discs used as coated abrasives. These discs are designed for use on hand-held grinding machines and are intended to be mounted on support discs compliant with ISO 15636. The standard establishes essential parameters such as dimensions, profiles, design features, and marking requirements to ensure compatibility, safety, and performance consistency across manufacturers and applications.

Key Topics

• Nominal Dimensions: ISO 16057:2002 defines the nominal diameters, hole sizes, and thickness tolerances for vulcanized fibre discs. The typical nominal diameters covered range from 80 mm to 235 mm with specific tolerance limits detailed for consistent sizing.

• Profiles and Designs: The standard identifies several disc profiles (A1, A2, B1, B2, C1, C2) that describe the shape and slot arrangements of the discs. Profiles may be flat or moulded, and slot quantities can be 4, 6, or 8 depending on the profile and manufacturer discretion.

• Test Conditions: Standardized environmental conditions for testing vulcanized fibre discs are specified, requiring storage and measurements under stable temperature (20 °C ± 2 °C) and humidity (65% ± 5%) conditions, in alignment with ISO 554.

• Designation and Marking: To ensure traceability and correct usage, the standard mandates specific disc designations incorporating profile type, diameter, hole size, shape (flat or moulded), and slot number. Required markings include grain size, manufacturer or supplier identification, and the maximum operating speed for safety purposes.

Applications

The vulcanized fibre discs standardized by ISO 16057:2002 are extensively used in:

• Hand-Held Grinding Machines: Ideal for surface conditioning, shaping, and finishing tasks where a durable coated abrasive disc is needed for efficient material removal.

• Metalworking and Fabrication: Suitable for grinding and deburring processes involving metals, enhancing precision and surface quality.

• Maintenance and Repair: Used in workshop environments for refurbishing tools, automotive parts, and industrial equipment requiring consistent abrasive performance.

• Support Disc Compatibility: These fibre discs are designed to be used with support discs conforming to ISO 15636, ensuring secure attachment and operational safety during grinding.

By adhering to ISO 16057:2002, manufacturers and users benefit from internationally harmonized specifications that promote quality, interchangeability, and user safety.
