TS EN 1005-1+A1

TS EN 1005-1+A1 is the terms and definitions standard for concepts related to human physical performance in machinery. It establishes the common vocabulary used across the rest of the EN 1005 series, so that ergonomic quantities such as force, posture, reach, repetition and related parameters are understood consistently. Rather than prescribing a test method itself, this document defines the language and conceptual boundaries used in those assessments.

Terminology used across the EN 1005 series

The scope covers terms and definitions for the concepts and parameters used in EN 1005-2, prEN 1005-3, EN 1005-4 and EN 1005-5. In practical machinery design, that shared terminology matters because it links human capability to machine geometry, operating conditions and task demands. A common vocabulary helps prevent ambiguity when discussing ergonomic risks, layout constraints or performance-related design choices.

Why the definitions matter in machinery ergonomics

In general technical context, human physical performance involves factors such as strength, posture, range of motion, repetitiveness, endurance and physical workload. Standards in this field support a design approach that aligns machinery with the user’s abilities during operation, adjustment and maintenance. TS EN 1005-1+A1 contributes by defining the terminology on which the more technical parts of the series rely, helping those later assessments remain consistent and comparable.

• This is a terms-and-definitions part, not a measurement-method standard.
• It harmonizes the concepts used throughout the rest of the series.
• It clarifies the vocabulary linking machinery safety and ergonomics.
• It supports consistent interpretation of human physical performance parameters.
