ISO 4094:2017为寻求成为“授权实验室（ALs）”并保持其3级光学参考传输标准发布授权实验室状态的实验室提供了一般要求和具体要求（附录A）。本文件遵循要求，采用ISO/IEC 17025的格式，旨在: a） 建立和维护可追溯至标准化实验室维护的国际光学参考一级标准（IR1）的2级国际光学参考传递标准（IR2）； b） 分发所需的可追溯性，以实现国际纸张、纸板或纸浆光学性能标准中规定的试验方法结果的实验室间一致性； c） 参与新方法的设计和开发以及程序的国际协调。 如果实验室未开展本文件所涵盖的一项或多项活动，如取样和新方法的设计/开发，则这些条款的要求不适用。 ISO 4094:2017适用于授权发布光学参考传输标准的指定实验室，用于开发其质量、行政和技术操作管理体系。实验室客户、监管机构和认证机构也可以使用它来确认或认可实验室的能力。 注:可能有必要解释或解释本文件中的某些要求，以确保以一致的方式应用这些要求。 一致性应用指南可从技术委员会ISO/TC 6获得。

ISO 4094:2017 provides both general requirements and specific requirements (Annex A) for laboratories seeking to become "Authorized Laboratories (ALs)" and to maintain their Authorized Laboratory status for the issue of optical reference transfer standards of level 3. This document follows the requirements and adopts the format of ISO/IEC 17025, with the aims of: a) establishing and maintaining international optical reference transfer standards of level 2 (IR2) traceable to an international optical reference primary standard of level 1 (IR1) maintained by a standardizing laboratory; b) distributing traceability required to achieve inter-laboratory agreement in the results of test methods specified in International Standards for optical properties of paper, board or pulp; c) participating in the design and development of new methods and international harmonization of procedures. When a laboratory does not undertake one or more of the activities covered by this document, such as sampling and the design/development of new methods, the requirements of those clauses do not apply. ISO 4094:2017 is for use by specified laboratories authorized to issue optical reference transfer standards in developing their management system for quality, administrative and technical operations. Laboratory customers, regulatory authorities and accreditation bodies can also use it in confirming or recognizing the competence of laboratories. NOTE It might be necessary to explain or interpret certain requirements in this document to ensure that the requirements are applied in a consistent manner. Guidance for consistent application can be obtained from Technical Committee ISO/TC 6.
