1.1本规程涵盖了设计工程界在工程图纸上可能使用的标准符号，以指示任何类型粘合剂的粘接组件。 1.2本设计基于ANSI/AWS A2.4以及ISO 15785中包含的标准。 1.3以国际单位制给出的数值应视为标准。括号中的值仅供参考。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 粘合剂符号提供了在工程图纸上放置有关粘合剂的完整信息的有效方法。接头是箭头线指向的符号的参考基础。符号的参考线用于指定要使用的粘合剂类型，包括关于其物理形式、化学技术系列、表面处理要求、应用方法（涂条与滚涂）和固化方法的信息。 可选尾部（如图1左侧所示）提供了一个位置，以包括其他符号中未提及的关于粘合剂的附加信息。 请参阅图1，以获取由用字母支撑圆的桅杆表示的粘附符号的概图 “ A. ” 内部用于粘合。在第5节的相应表格中，可以找到每个元素背后的详细信息（例如，形式、化学、应用方法）。 图1粘合剂符号元件的标准位置

1.1 This practice covers a standard symbol that may be used by the design-engineering community on engineering drawings to indicate a bonded assembly for any type of adhesive. 1.2 This design is based on criteria contained in ANSI/AWS A2.4 as well as ISO 15785. 1.3 The values given in SI units are to be regarded as the standard. The values in parentheses are for information only. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== An adhesive symbol provides an efficient means of placing complete information about adhesives on engineering drawings. The joint is the basis of reference for the symbol to which the arrow line is pointed. The reference line of the symbol is used to designate the type of adhesive to be used, including information about its physical form, chemical technology family, requirements for surface preparation, application method (bead versus roll coat), and cure method. The optional tail (shown at left in Fig. 1) provides a place to include additional information about the adhesive that is not referenced in other notations. Refer to Fig. 1 for an overview schematic of the adhesive symbol denoted by a mast supporting a circle with the letter “ A ” inside for adhesive. Detail behind each of the elements noted (for example, FORM, CHEM, APPL METH) can be found in corresponding tables in Section 5. FIG. 1 Standard Locations of Elements of the Adhesive Symbol
