Procurement Specification Guidelines for Mass Transit Vehicle Window Glazing

摘要

This report will be of interest to transmit maintenance and procurementspecialists concerned with purchasing windows and window systems. The report provides detailed guidelines for the development of specifications for the procurement of durable and vandal-resistant bus and rail vehicle passenger-side windows and window systems. The guidelines provide information on the different types of window systems and materials; their strengths, weaknesses, special features, and costs; and other information. The guidelines also include specific tests and acceptance criteria that can be used to assess durability, as well as recommend practices for ensuring that the procured window glazing system is easily replaced, and that repair and refurbishment are considered up-front during the initial specification-development process. Aerospace coating and transparency technologies, as well as sacrificial plies, peel-ply protective films, and anti-spall films are covered.
