1 Scope

GB/T 28886-2023 is the product standard for PVC and other plastic windows and doors in buildings. They dominate residential construction because they insulate well and need no painting, and they fail in ways that are peculiar to the material: the profile is a hollow extrusion whose stiffness depends on internal steel reinforcement that cannot be seen once installed, the material moves substantially with temperature so corner welds carry real stress, and it degrades under ultraviolet light unless the compound is formulated for it. None of that is visible to a buyer comparing two windows that look identical, and the difference appears five years later as sagging sashes, failed welds and yellowed frames. This document specifies the classification, specifications, series and markings for plastic doors and windows used in construction, the general requirements and technical requirements, the test methods, the inspection rules, and the marking and accompanying documentation. Under ICS 91.060.50 and CCS P32, it is written for window and door manufacturers and their profile suppliers, for architects and contractors specifying them, and for the construction quality inspection bodies who verify what was installed.

This document specifies the classification, specifications, series and markings, general requirements, technical requirements, test methods, and inspection regulations for plastic doors and windows used in construction: Rules, markings and accompanying documents, packaging, transportation and storage: This document applies to PVC-U plastic doors and PVC-U plastic windows for construction:
