ISO 9022-11:2015规定了与光学仪器（包括其他领域（如机械、化学和电子设备）在同等条件下的附加组件）环境试验有关的方法，以确定其抵抗霉菌生长影响的能力。然而，只有在特殊情况下，才能按照ISO 9022-11:2015的规定对完整的仪器或组件进行测试。通常情况下，代表性样品（如安装的光学元件、材料样品或代表性样品上的表面涂层）用于测试。 ISO 9022-11:2015中描述的试验旨在为可能在有利于霉菌生长的环境中使用的仪器选择材料和组件，而不是用于常规生产控制。 测试的目的是调查霉菌生长对试样的光学、气候、机械、化学和电气（包括静电）性能特性的影响程度。 此外，ISO 9022-11:2015中的测试旨在评估真菌排出的代谢废物（如酶或酸）在多大程度上导致蚀刻、腐蚀或短路，例如印刷电路板。

ISO 9022-11:2015 specifies the methods relating to the environmental tests of optical instruments, including additional assemblies from other fields (e.g. mechanical, chemical, and electronic devices) under equivalent conditions, for their ability to resist the influence of mould growth. However, complete instruments or assemblies are only tested as specified in ISO 9022-11:2015 in exceptional cases. Normally, representative specimens such as mounted optics, material samples, or surface coatings on representative samples are used for testing. The tests described in ISO 9022-11:2015 are designed for the selection of materials and components for instruments likely to be used in an environment that is conducive to mould growth, rather than for regular production control. The purpose of testing is to investigate to what extent the optical, climatic, mechanical, chemical and electrical (including electrostatic) performance characteristics of the specimen are affected by mould growth. In addition, the tests in ISO 9022-11:2015 are designed to assess to what extent metabolic waste products (such as enzymes or acids) excreted by fungi, cause etching, corrosion, or short-circuits on, for instance, printed circuit boards.
