本标准通过在发射前在地面上测试空间段元件和空间段设备来满足执行验证的要求。该文件适用于对资格模型，飞行模型（在验收级别进行测试）和原型模型执行的测试。 标准规定: •测试程序和测试管理的要求， •重新测试的要求， •冗余测试要求， •环境测试要求， •功能和性能测试的一般要求， 注意功能和性能测试的具体要求不是本标准的一部分，因为它们在具体项目文档中定义。 •资格认证，验收和原始测试的要求，包括资格认证，验收和原型机型的测试利润率和持续时间， •测试因素，测试条件，测试公差和测试准确度的要求， •与资格考试计划开始相关的开发测试的一般要求， 注意开发测试是具体的，并在各种工程学科标准中得到解决。 •测试活动所需文件的内容（例如DRD）。 由于以下类型的测试的具体方面

This standard addresses the requirements for performing verification by testing of space segment elements and space segment equipment on ground prior to launch. The document is applicable for tests performed on qualification models, flight models (tested at acceptance level) and protoflight models. The standard provides: • Requirements for test programme and test management, • Requirements for retesting, • Requirements for redundancy testing, • Requirements for environmental tests, • General requirements for functional and performance tests, NOTE Specific requirements for functional and performance tests are not part of this standard since they are defined in the specific project documentation. • Requirements for qualification, acceptance, and protoflight testing including qualification, acceptance, and proto-fight models’ test margins and duration, • Requirements for test factors, test condition, test tolerances, and test accuracies, • General requirements for development tests pertinent to the start of the qualification test programme, NOTE Development tests are specific and are addressed in various engineering discipline standards. • Content of the necessary documentation for testing activities (e.g. DRD). Due to the specific aspects of the following types of test, this Standard does not address: • Space system testing (i.e. testing above space segment element), in particular the system validation test, • In-orbit testing, • Testing of space segment subsystems, NOTE Tests of space segment subsystems are often limited to functional tests that, in some case, are run on dedicated models. If relevant, qualification tests for space segment subsystems are assumed to be covered in the relevant discipline standards. • Testing of hardware below space segment equipment levels (including assembly, parts, and components), • Testing of stand-alone software, NOTE For verification of flight or ground software, ECSS-E-ST-40 and ECSS-Q-ST-80 apply. • Qualification testing of two-phase heat transport equipment, NOTE For qualification testing of two-phase heat transport equipment, ECSS-E-ST-31-02 applies. • Tests of launcher segment, subsystem and equipment, and launch facilities, • Tests of facilities and ground support equipment, • Tests of ground segment. This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00. Annex D gives guidelines for performing this tailoring.
