ISO/IEC TR 18121:2015定义了支持IT增强学习、教育和培训的虚拟实验的IT标准和规范框架。它基于标准和规范的实施，这些标准和规范用于支持依赖ITLET的虚拟实验、开发、评估和管理。 本ISO/IEC TR 18121:2015 -提供了一个可用于依赖ITLET的虚拟实验系统的框架， -确定不同虚拟实验标准和规范的类别以及它们之间的关系，以促进它们的集成， -促进虚拟实验组件的适当设计和应用，以使正在使用的IT系统可重复使用、成本低、适用范围更广， -表示在开发正在开发或用于支持虚拟实验系统的ITLET系统时要考虑的因素， -提供虚拟实验系统框架的示例架构，可用于支持虚拟实验的进一步开发， -说明了不同参与者在虚拟实验系统中的不同位置可以扮演的不同角色， -演示如何将支持虚拟实验的标准和规范结合起来，形成未来工作和实现的基础。 本ISO/IEC TR 18121:2015未涉及以下方面: -虚拟实验系统的实现细节说明； -可达性； -隐私； -保安。

ISO/IEC TR 18121:2015 defines the framework for IT standards and specifications on virtual experiments supporting IT-enhanced learning, education and training. It is based on implementations of standards and specifications that are used to support virtual experiment, development, evaluation and management that rely on ITLET. This ISO/IEC TR 18121:2015 - provides a framework that can be used for virtual experiment systems that rely on ITLET, - determines the categories of different virtual experiment standards and specifications and their relationships to facilitate their integration, - promotes the appropriate design and application of virtual experiment components so that IT systems that are being used are reusable, low cost, and more broadly applicable, - indicates considerations to be taken into account when developing ITLET systems that are being developed or used to support virtual experiment systems, - provides sample architecture of a virtual experiment system framework that can be used to support further development of virtual experiments, - illustrates various roles that different actors can have at various points within the virtual experiment system, - demonstrates how standards and specifications that support virtual experiments can be combined to form the basis for future work and implementations. The following aspects are not addressed in this ISO/IEC TR 18121:2015: - specifications of the implementation details of virtual experiment systems; - accessibility; - privacy; - security.
