TS EN 131-1

TS EN 131-1 is the Turkish adoption of the standard that establishes the core terminology, ladder types and functional sizes for ladders, with a focus on portable ladders. Standards of this kind give manufacturers, specifiers and users a common technical language for identifying ladder forms and comparing design dimensions in a consistent way.

Why terminology and functional sizes matter

The standard organizes the names used for ladder components and defines the general design characteristics associated with them. In general technical terms, ladder geometry such as rung spacing, width, length, inclination and support arrangement is central to how a ladder is described, selected and used. Functional sizes provide the dimensional framework that links the product’s physical form to its intended function and category.

Defined boundaries of the document

• It applies to portable ladders.
• It does not apply to ladders designed for specific professional use such as fire brigade ladders, roof ladders and mobile ladders.
• For multiple hinge joint ladders, EN 131-4 applies; for telescopic ladders, EN 131-6 applies; and for mobile ladders with platforms, EN 131-7 applies.
• Step stools are outside the scope of this standard and are covered by EN 14183.

As a vocabulary-and-dimensions standard, this document supports consistent technical communication and product classification across the ladder family. More specialized EN 131 parts address particular ladder constructions separately, which helps keep the terminology clear while allowing each ladder type to be treated under its own detailed standard.
