ISO/IEC 29109-1:2009定义了生物特征数据交换格式一致性测试的概念，并定义了通用一致性测试框架。它规定了测试方法的通用（模态中立）元素，例如测试方法和程序、实现一致性声明和测试结果报告。它还提供了断言语言定义，阐述了其他测试和报告要求，并概述了一致性测试方法的其他方面，这些方面通常适用，而不是特定于模态。作为一致性测试方法的一部分，描述了不同类型和级别的一致性测试，以及它们的适用性。ISO/IEC 29109-1:2009中规定的一致性测试方法仅涉及数据交换格式记录以及产生或使用这些记录的系统。

ISO/IEC 29109-1:2009 defines the concepts of conformance testing for biometric data interchange formats and defines a general conformance testing framework. It specifies common (modality-neutral) elements of the testing methodology, such as test methods and procedures, implementation conformance claim, and test results reporting. It also provides the assertion language definition and sets forth other testing and reporting requirements, and outlines other aspects of the conformance testing methodology that are generally applicable and not modality-specific. As part of the conformance testing methodology, different types and levels of conformance testing are described, as well as their applicability. The conformance testing methodology specified in ISO/IEC 29109-1:2009 is concerned only with data interchange format records and systems that produce or use these records.
