本标准由门和五金研究所在A115系列单独标准中首次发布 这些标准现在被合并成钢和木门的单一文件。ANSI认证 是通过拉票的方式获得的。BHMA于1983年3月21日被ANSI认证为 赞助商使用拉票法。本标准涵盖了安装通用硬件的所有重要尺寸属性 木门和金属或木框架产品。所有尺寸应如图纸所示 附图。 制定本标准的目的是仅展示最常用的门用制剂 硬件，并提供标准化目标。多个配置是共同的 使用时，提供了单独的图纸。对于其他配置，公认这些标准 可以部分使用，也可以例外，但仍提供一定程度的基本指导和 标准化。

This Standard was first published by the Door and Hardware Institute in a series of individual A115 standards, which are now combined into single documents for steel and wood doors. ANSI approval was secured under the Canvass Method. BHMA was accredited on 21 March 1983 by ANSI as a sponsor using the Canvass Method.This Standard covers all significant dimensional attributes for mounting common hardware products in wood doors and metal or wood frames. All dimensions shall be as shown on the accompanying drawings.This standard was developed to show only the most commonly used preparations for door hardware, and provide targets for standardization. Where multiple configurations are in common usage, separate drawings are provided. For other configurations, it is recognized that these standards may be used in part, or with exceptions, while still providing some degree of basic guidance and standardization.
