The phrase denotes the act of acquiring, at no cost, a digital document adhering to the International Organization for Standardization (ISO) standard numbered 23894. This standard pertains to fire safety engineering, specifically focusing on planning, design, installation, commissioning, testing, and maintenance of smoke control systems.
Access to documentation related to this standard allows professionals in fire safety to implement and maintain compliant systems. The existence of such free resources facilitates wider understanding and application of best practices, potentially improving safety outcomes in various built environments. Historically, access to ISO standards required purchase, but the demand for broader knowledge has led to the search for freely available copies, even though copyright restrictions may exist.
