1.1 本规范涵盖了将预制隔音材料粘接到建筑物房间内墙和天花板上的粘合剂。这种粘合剂需要保持不低于3.45×10的拉伸附着力（粘合强度） 4. 达因/厘米 2. ( 1. / 2. 磅/英寸。 2. )在可能遇到的温度和湿度条件下长时间保持，并保持足够的塑性，以允许建筑物的部分在老化时移动。 注1: 表面清洁度 -声学材料涂有粘合剂的表面应清洁、完好、干燥。如果表面涂层的性质表明安装不符合要求，则应去除表面涂层，以便将粘合剂涂抹在基层上。 当将粘合剂涂敷在涂漆表面上时，应将测试砖涂敷48小时，以通过检查确定涂层的适当粘附性。声学粘合剂不适用于潮湿和有碱性反应的表面，或以后可能变得潮湿或碱性的表面。此类表面（如混凝土或灰泥）应在涂抹粘合剂之前适当干燥和老化。 注2: 负载 -不建议将这种粘合剂作为固定重量超过121 kg/m的声学材料的唯一方法 2. (2 1. / 2. 磅/英尺 2. )至天花板表面。 注3: 材料的数量和条件 -建议使用足够的粘合剂，使接触面不小于1.2×10 4. 厘米 2. /m 2. （20英寸。 2. /英尺 2. )隔音材料，最小厚度为0.3 cm( 1. / 8. 英寸。）对于标准的30.5×30.5厘米（12×12英寸），粘合剂应涂抹在靠近角落的四个大小大致相同的独立近球形部分瓦片对于30.5×30.5厘米的瓷砖，不建议少于或多于四个部分，因为难以找平和确保所有部分的有效接触面积。不应使用坚硬、不润湿表面或难以涂抹的粘合剂。 注4: 基础表面的刚度 -形成粘合剂附着的基底的材料必须相对光滑、牢固和刚性。如果铺贴瓷砖和粘合剂的压力导致基材过度偏转，则先前铺贴的瓷砖的粘合剂可能会断裂。 这种情况发生在某些类型的石膏板悬挂系统上。 注5: 变老 -到目前为止，还没有针对粘合剂进行加速老化试验，以准确复制使用中的老化。本规范中的老化试验旨在加速老化过程，并测试老化的各种表现，旨在满足比较一种粘合剂与另一种粘合剂的要求；它们不一定绝对反映年龄特征。粘合剂的购买者应获得制造商对粘合剂在正常老化下性能的额外保证和保证。 注6: 安装实践 -正确的安装技术对于任何声学粘合剂的正确性能至关重要。使用符合本规范的材料本身不能保证令人满意的性能。 只有由熟练且经验丰富的工人按照制造商的指示使用瓷砖，才能确保买方获得满意的粘合剂性能。 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 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、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers an adhesive for bonding prefabricated acoustical materials to the inside walls and ceilings of rooms in buildings. This adhesive is required to maintain a tensile adhesion (bond strength) of not less than 3.45 × 10 4 dynes/cm 2 ( 1 / 2 lb/in. 2 ) for a long period of time under the temperature and moisture conditions likely to be encountered and to maintain sufficient plasticity to allow for movement of parts of the building as it ages. Note 1: Cleanliness of Surface —The surface to which the acoustical material is applied with the adhesive should be clean, sound, and dry. Surface coatings should be removed if their nature indicates an unsatisfactory installation, so that the adhesive can be applied to the base. When the adhesive is to be applied on a painted surface, test tile should be applied for 48 h to determine suitable adherence of the coating by examination. Acoustical adhesives are not intended to be applied to surfaces that are moist and that have an alkaline reaction, or that may later become moist or alkaline. Such surfaces, as concrete or plaster, should be properly dried and aged before applying the adhesive. Note 2: Load —This adhesive is not recommended as a sole means of holding acoustical materials weighing more than 121 kg/m 2 (2 1 / 2 lb/ft 2 ) to ceiling surfaces. Note 3: Amount and Condition of Material —It is recommended that sufficient adhesive be used so that there is a contact surface of not less than 1.2 × 10 4 cm 2 /m 2 (20 in. 2 /ft 2 ) of acoustical material, with a minimum thickness of 0.3 cm ( 1 / 8 in.) and that the adhesive be applied in four separate nearly spherical portions of approximately equal size near the corners for a standard 30.5 by 30.5-cm (12 by 12-in.) tile. Fewer than or more than four portions for 30.5 by 30.5-cm tile are not recommended due to difficulty in leveling and in securing effective contact area on all portions. Adhesives that are hard, or do not wet the surface, or are difficult to spread should not be used. Note 4: Rigidity of Base Surfaces —It is necessary that the material forming the base to which the adhesive is attached should be relatively smooth, firm, and rigid. If the pressure of applying tile and adhesive causes the base material to deflect excessively, tile previously applied may have their adhesive bond broken. This occurs on some types of gypsum board suspension systems. Note 5: Aging —To date, no accelerated aging tests for adhesives have been developed to duplicate exactly aging in service. The aging tests in this specification are designed to accelerate the aging process and to test various manifestations of aging, and are intended to be satisfactory for comparing one adhesive with another; they do not necessarily reflect aging characteristics on an absolute basis. Purchasers of adhesives should receive from the manufacturer additional warranties and assurances of performance of the adhesive under normal aging. Note 6: Erection Practices —Proper erection techniques are essential for proper performance of any acoustical adhesive. Use of a material meeting this specification will not in itself guarantee satisfactory performance. Only when tiles are applied by skilled and experienced workers following instructions from the manufacturer can the purchaser be assured of satisfactory performance of an adhesive. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
