1.1 本规程涵盖了用户之间通过调制解调器或电子媒体的物理传输进行颜色和外观数据电子交换的程序。它旨在供颜色测量仪器制造商和软件开发人员使用，以便任何仪器都可以获取其使用的数据，这些数据可能是在另一制造商的仪器上、在另一个地方或在另一个时间测量的。 1.2 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 当需要在仪器或计算机之间传输颜色和外观数据，并且ASCII文件是所需的传输方法时，颜色测量仪器制造商和软件开发人员应使用本规程。 5.2 传输方法可以是通过直接连接、调制解调器或电子媒体的传输，例如通过软盘传输。 5.3 这种做法有助于传输单个数据记录或多个记录文件。 5.4 本实践中生成的文件示例包含在 图X1.1 和 图X2.1 属于 附录X1 和 附录X2 .

1.1 This practice covers procedures to be used in the electronic exchange of color and appearance data between users, by either modem or the physical transfer of electronic media. It is intended for use by manufacturers of color-measuring instruments and developers of software so that any instrument may acquire data for its use that may have been measured on an instrument of another manufacturer, at another place, or at another time. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This practice should be used by manufacturers of color-measuring instruments and developers of software when the transmission of color and appearance data is desired between instruments or computers and where ASCII files are the desired method of transfer. 5.2 The method of transmission may be via direct connection, modem, or the transfer of electronic media, for example, by floppy disk transfer. 5.3 The practice lends itself to the transmission of either a single record of data or multiple record files. 5.4 Examples of files generated in this practice are contained in Fig. X1.1 and Fig. X2.1 of Appendix X1 and Appendix X2 .
