What is ISO 55138:2014 ?

ISO 55118:2014 is a technical standard developed by the International Organization for Standardization (ISO) that specifies requirements and guidelines for the design, installation, and operation of pedestrian accessible tactile ground surface indicators (TGSIs) in order to assist people with visual impairments or other disabilities in safely navigating the built environment.

The main purpose of ISO 55118:2014 is to provide a standardized approach for the implementation of TGSIs, which are the truncated domes or detectable warning surfaces found on sidewalks, ramps, transit platforms, and other public spaces. These TGSIs serve as a tactile guide for individuals who rely on their sense of touch to move around and avoid potential hazards.

Key Requirements of ISO 55118:2014 include:

* TGSIs should be placed at visible height and be easily accessible to people with disabilities.

* The shape, size, and color of TGSIs should be clearly labeled and easy to understand.

* The materials used to construct TGSIs should be durable and non-slip.

* TGSIs should be designed to provide a clear and unobstructed view of the underlying surface.

* TGSIs should be easily removable and replaceable when necessary.

ISO 55148:2014 is a technical document that provides guidelines for writing easy-to-understand technical articles. Its main purpose is to ensure that complex technical information can be effectively communicated to readers in a clear and concise manner.

Key Components of ISO 55148:2014 include:

* A clear and concise writing style.

* Use of technical terms and definitions.

* Use of images and diagrams to help explain technical information.

* A clear and logical structure of the article.

* A focus on the intended audience and their level of technical knowledge.

In conclusion, ISO 55118:2014 is a technical standard that provides guidelines for the design, installation, and operation of TGSIs in order to assist people with visual impairments or other disabilities in safely navigating the built environment. It is important to follow the requirements and guidelines set out in ISO 55118:2014 to ensure that TGSIs are effective and meet the needs of individuals with disabilities.
