Overview

ISO 14738:2002/Cor 2:2005 is a key technical corrigendum to the international standard ISO 14738:2002, focusing on the safety of machinery through anthropometric requirements in the design of machinery workstations. This corrigendum provides important updates and clarifications that enhance ergonomic safety by specifying detailed anthropometric dimensions and postural guidelines for machinery operators.

Prepared collaboratively by the European Committee for Standardization (CEN) and ISO Technical Committee ISO/TC 159/SC 3 on ergonomics and anthropometry, this corrigendum aims to ensure safer, more comfortable, and efficient working environments at machinery workstations.

Key Topics

• Anthropometric Design Requirements
  The corrigendum updates specific measurement tables to provide precise dimensions for workstation design. It addresses legroom, foot space, and working surface height requirements, ensuring they accommodate a wide range of human body sizes based on percentile anthropometric data (P5 and P95).

• Posture Guidelines
  A noteworthy addition is the advisory that certain postures depicted in the standard should only be maintained for short durations to minimize ergonomic risks such as strain and injury.

• Space Requirements for Sitting Posture
  Detailed tables specify space needed for legs, feet, and knee clearance when seated at machinery workstations. For example, Table 5 defines adjustable and non-adjustable working surface heights, leg space depth and width, footrest heights, and seating heights based on anthropometric formulas.

• Adjustability of Workstations
  Emphasizes the need for adjustable features like working surface height and footrests to accommodate the anthropometric variability in operators, contributing to improved comfort and reduced fatigue.

• Technical Precision
  Clarifications in measurement alignment and formula applications provide better consistency and practical usability of the standard.

Applications

ISO 14738:2002/Cor 2:2005 is essential for designers, manufacturers, and safety engineers involved in creating or assessing machinery workstations. Practical applications include:

• Designing ergonomic machinery controls and work areas that fit a diverse workforce, reducing the risk of musculoskeletal disorders.
• Establishing workplace safety protocols by ensuring workstations comply with up-to-date anthropometric standards.
• Integrating adjustable features in machinery to allow customization according to operator size, improving productivity and comfort.
• Providing clear specifications for space allocation around machinery for seated operators, aiding in factory layout and ergonomic assessments.
• Enhancing compliance with international safety regulations by using recognized standards in machinery design.

Related Standards

To develop comprehensive ergonomics and safety frameworks in machinery design, ISO 14738:2002/Cor 2:2005 can be used alongside the following standards:

• ISO 12100 – Safety of machinery: General principles for design
  Provides foundational guidelines for risk assessment and risk reduction in machinery design.

• ISO 6385 – Ergonomic principles in the design of work systems
  Covers broader ergonomic practices applicable to workplaces including machinery.

• ISO 9241 – Ergonomics of human-system interaction
  Focuses on ergonomic requirements for interactive systems, complementing physical workstation design.

• ISO/TC 159 – Ergonomics series
  Encompasses multiple standards dealing with anthropometry, biomechanics, posture analysis, and human factors in product design.
