ISO/IEC 15444-4:20 04规定了要求符合ISO/IEC 15444-1的框架、概念、测试方法和标准。它提供了一个用于指定抽象测试套件和定义符合性测试期间要遵循的程序的框架。ISO/IEC 15444-4:20 04:指定使用JPEG 2000第1部分（ISO/IEC 15444-1）进行编码和解码的符合性测试程序；指定与测试程序一起使用的码流、解码图像和错误度量；指定抽象测试套件；并为创建编码器合规性测试提供指导。ISO/IEC 15444-4:20 04不包括以下测试:验收测试:确定实现是否满足验收标准并使用户能够确定是否接受该实现的过程。这包括规划和执行几种测试（如功能、质量和速度性能测试），以证明实现满足用户要求。性能测试:测量被测试实现（IUT）的性能特征，如吞吐量、响应性等。在各种条件下。健壮性测试:确定实现处理包含错误数据的能力的过程。

ISO/IEC 15444-4:2004 specifies the framework, concepts, methodology for testing, and criteria to be achieved to claim compliance with ISO/IEC 15444-1. It provides a framework for specifying abstract test suites and for defining the procedures to be followed during compliance testing.

ISO/IEC 15444-4:2004:

Specifies compliance testing procedures for encoding and decoding using JPEG 2000 Part 1 (ISO/IEC 15444-1);
Specifies codestreams, decoded images and error metrics to be used with the testing procedures;
Specifies abstract test suites; and
Provides guidance for creating an encoder compliance test.

ISO/IEC 15444-4:2004 does not include the following tests:

Acceptance testing: the process of determining whether an implementation satisfies acceptance criteria and enables the user to determine whether or not to accept the implementation. This includes the planning and execution of several kinds of tests (e.g. functionality, quality and speed performance testing) that demonstrate the implementation satisfies the user requirements.
Performance testing: measuring the performance characteristics of an Implementation Under Test (IUT), such as its throughput, responsiveness, etc., under various conditions.
Robustness testing: the process of determining how well an implementation processes data which contains errors.
