本报告的目的是帮助照明程序用户和开发人员评估照明计算机程序的准确性，并确定其弱点。因此，基于单独测试光传播的不同方面的概念，提出了一种验证方法。为了应用这种方法，设计了一套测试用例，其中每个测试用例都突出了照明模拟领域的一个给定方面，并与相关参考数据相关联。使用两种类型的参考数据:基于分析计算的数据和基于实验测量的数据。第一种是与避免参考值不确定性的理论情景相关的。第二种类型是通过实验测量获得的，其中场景和协议的定义方式将与测量相关的不确定性降至最低。 为了获得用于验证的可靠实验数据，还提出了一组建议。这些建议涉及场景的选择和描述、实验方案的预防措施、误差源的估计以及参考数据的呈现。报告用英文写成，并附有法文和德文的简短摘要。它由97页27幅图和65张表组成。

The objective of this report is to help lighting program users and developers assess the accuracy of lighting computer programs and to identify their weaknesses. A validation approach is therefore presented based on the concept of separately testing the different aspects of light propagation. To apply this approach, a suite of test cases has been designed where each test case highlights a given aspect of the lighting simulation domain and is associated with the related reference data.Two types of reference data are used: data based on analytical calculation and data based on experimental measurements. The first is associated with theoretical scenarios that avoid uncertainties in the reference values. The second type is obtained through experimental measurements, where the scenario and the protocol are defined in a manner that minimizes the uncertainties associated with the measurements.A set of recommendations is also presented in order to achieve reliable experimental data for validation purposes. These recommendations address the choice and description of the scenarios, to the experimental protocol precautions, to the estimation of the error sources and to the presentation of the reference data.The report is written in English, with a short summary in French and German. It consists of 97 pages with 27 figures and 65 tables.
