ISO/IEC 24709-2:2007定义了一些用ISO/IEC 24709-1中规定的断言语言编写的测试断言。这些断言使ISO/IEC 24709-2:2007的用户（如测试实验室）能够测试任何声称符合该国际标准的生物特征服务提供商（BSP）是否符合ISO/IEC 19784-1（BioAPI 2.0）。ISO/IEC 24709-2:2007中规定的每个测试断言都具有测试中实现的一个或多个特性。根据断言语言的要求，断言被放入包中（每个包一个或多个断言）。这些断言允许测试所有一致性子类的BSP的一致性，并根据一致性子类别和声称的对可选特性的支持进行进一步组织。

ISO/IEC 24709-2:2007 defines a number of test assertions written in the assertion language specified in ISO/IEC 24709-1. These assertions enable a user of ISO/IEC 24709-2:2007 (such as a testing laboratory) to test the conformance to ISO/IEC 19784-1 (BioAPI 2.0) of any biometric service provider (BSP) that claims to be a conforming implementation of that International Standard. Each test assertion specified in ISO/IEC 24709-2:2007 exercises one or more features of an implementation under test. Assertions are placed into packages (one or more assertions per package) as required by the assertion language. These assertions allow for testing conformance of BSPs of all conformance subclasses, and are further organized according to conformance subclasses and claimed support of optional features.
