適用范圍：This document gives the tolerance limits for general and local flatness of door leaves. It applies to door leaves which are supplied without, and independent of, any frames. It does not apply to the leaves of doorsets. The overall general flatness of a door leaf may be important in satisfying both visual and performance requirements. Local flatness, as defined in the document, is only concerned with the visual effect of surface undulations over small areas of the face of a door leaf. Moreover it is important to recognise that the visibility of such undulations depends upon the degree of light reflection, based upon the level of glass and the angle of light. Under extreme gloss/light conditions, undulations of as little as 0,025 mm may be discerned.#,,#
