ISO 5169:1977

Overview

ISO 5169:1977 is an important international standard published by the International Organization for Standardization (ISO) that provides comprehensive guidance on the presentation of lubrication instructions for machine tools. It aims to assist both manufacturers and users by defining the essential information and format required to ensure effective lubrication management and maintenance of machine tools. This standard enhances machine reliability, safety, and operational efficiency through clear, standardized lubrication documentation.

Key Topics

• Lubrication Instructions Content
  ISO 5169 specifies that lubrication instructions must clearly identify:

  • Machine components requiring lubrication
  • Exact locations of all lubrication and action points
  • Types of lubrication actions (inspection, replenishment, cleaning, lubricant change, actuation of levers)
  • Designations of lubricants in accordance with ISO lubricant standards
  • Capacity of lubricant reservoirs
  • Recommended time intervals for lubrication activities based on machine running hours

• Technical Documentation
  The standard recommends compiling all lubrication information into a single comprehensive document termed the “Lubrication instructions,” which may be part of the general machine tool manual. This document should be detailed yet clear, allowing easy understanding for maintenance teams.

• Visual Representation
  To avoid misunderstandings, lubrication instructions should include simplified diagrams, photographs, or schematic views of lubrication points and actions. These illustrations help users quickly identify lubrication tasks and their locations.

• Data Plates and Markings
  ISO 5169 advises the use of durable data plates attached to machines that incorporate key lubrication information. These plates:

  • Should be clearly visible and permanent on the machine
  • May include smaller plates near individual action points if preferred
  • Use ISO standardized symbols for actions and lubricant types
  • Provide details like action point number, lubrication method, lubricant type, and lubrication intervals

• Lubrication Time Intervals
  The manufacturer provides recommended lubrication intervals expressed in machine running hours. Users need to adapt these intervals based on actual machine usage, such as daily or weekly schedules.

Applications

ISO 5169:1977 applies to all machine tool manufacturers, maintenance personnel, and operators interested in proper lubrication management. Its practical applications include:

• Manufacturing Industry
  Machine tool makers use ISO 5169 to develop clear lubrication manuals, improving customer safety and equipment longevity.

• Maintenance Scheduling
  Maintenance teams establish routine lubrication schedules based on standardized intervals, ensuring optimum machine performance.

• Training and Compliance
  Consistent, standardized lubrication instructions help train maintenance staff and ensure compliance with industrial and safety regulations.

• Operational Efficiency
  Clear, concise lubrication guidelines reduce downtime caused by lubrication errors or neglect.

Related Standards

• ISO 369 – Symbols for indications on machine tools, providing visual vocabulary for lubrication symbols
• ISO 3498 – Specifies lubricant types for machine tools, ensuring compatibility and performance
• Additional ISO technical reports related to machine tool lubrication can complement ISO 5169 for comprehensive maintenance standards.

By following ISO 5169:1977, organizations can improve machine tool maintenance through standardized, easily understood lubrication instructions. This promotes safer working environments, reduced equipment wear, and enhanced productivity.
