What is ISO 55139:2014 ?

ISO 55139:2014 and ISO 55148:2014 are both technical standards developed by the International Organization for Standardization (ISO). ISO 55139:2014 is a technical standard 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.

ISO 55139:2014 aims 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.

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.

ISO 55148:2014 provides guidance on how to write about technical information in a way that is clear, concise, and easy to understand. It covers topics such as the use of technical terms and definitions, the organization of technical documents, and the use of examples and screenshots.

ISO 55148:2014 is a valuable tool for anyone who needs to communicate technical information effectively, including those with visual impairments who rely on touch to navigate public spaces. By following the guidelines provided in ISO 55148:2014, writers can ensure that their technical documents are accessible and easy to understand for readers with disabilities.
