ISO 7240-20:2010规定了建筑物内安装的火灾探测和报警系统中使用的吸气式烟雾探测器的要求、试验方法和性能标准。 ISO 7240-20:2010还涵盖了为保护包含特殊特性（包括ISO 7240-20:2010未定义测试或评估方法的附加特性或增强功能）的特定风险而开发的吸气式烟雾探测器。任何特殊特性的性能要求都超出了ISO 7240-20:2010的范围。

ISO 7240-20:2010 specifies the requirements, test methods and performance criteria for aspirating smoke detectors for use in fire detection and alarm systems installed in buildings. Aspirating smoke detectors developed for the protection of specific risks that incorporate special characteristics (including additional features or enhanced functionality for which ISO 7240-20:2010 does not define a test or assessment method) are also covered by ISO 7240-20:2010. The performance requirements for any special characteristics are beyond the scope of ISO 7240-20:2010.
