1.1 本指南为牙膏和牙刷感官评估专家评估员的选择和培训提供了指南，并为其感官评估提供了基本框架。牙膏和牙刷的感官评估可用于定义产品的感官属性，然后定量测量这些属性，以用于新产品开发、产品优化、竞争基准和索赔证明。 1.2 提供了牙膏和牙刷描述性分析的一般框架，以指导读者设计和执行此类评估（包括样品制备和展示、设施和测试环境以及具体评估方案）。 1.3 本指南提供了对所示产品/样品进行评估的建议方案和方法，绝不排除任何可能有效提供此类感知评估的替代方法。 1.4 本指南不涉及其他口腔护理产品，包括但不限于美白剂、漱口液、漱口水、牙线、假牙粘合剂、牙线牙签或其他口腔护理用品。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 本指南中推荐的牙刷和牙膏评估方法可用于评估使用中和使用后（或一系列使用）牙膏的感官特征。本指南旨在解决独立牙刷和牙膏产品的评估问题，不涉及包装、产品/包装相互作用、分配或产品的整体临床效果或益处。 本指南中概述的程序将由经过感官和描述能力专门筛选并接受过牙刷或牙膏或两者评估培训的评估人员使用。本指南中描述的程序可用于指导制造商内部的产品开发，并通过媒体或产品包装向消费者传达有关产品的信息。 5.2 此外，两份额外的ASTM国际感官指南（指南 第490页 和 2008年 )以及 感官评价词汇:香气、味道、质地和外观 （DS72-2ND） 4. 在本指南中使用。

1.1 This guide provides guidelines for the selection and training of expert assessors for the sensory evaluation of toothpaste and toothbrushes as well as a basic framework for the sensory evaluation of the same. Sensory evaluation of toothpaste and toothbrushes can be used to define the sensory attributes of the products and then to measure those attributes quantitatively for the purposes of new product development, product optimization, competitive benchmarking, and claims substantiation. 1.2 A general framework for both toothpaste and toothbrush descriptive analysis is provided to guide the reader in the design and execution (including sample preparation and presentation, facility and testing environment, and specific evaluation protocols) for such evaluations. 1.3 This guide provides suggested protocols and approaches to the evaluation of the indicated products/samples and in no way excludes any alternate approaches that may be effective in providing such perceptual evaluations. 1.4 This guide does not address other oral care products including, but not limited to, whitening agents, oral rinses, mouthwashes, dental flosses, denture adhesive, floss picks, or other oral care products. 1.5 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. 1.6 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 The approaches to the evaluation of toothbrushes and toothpaste recommended in this guide can be used to assess the sensory characteristics of toothpaste in use and after use (or a series of uses). This guide is meant to address the evaluation of standalone toothbrush and toothpaste products and does not address packaging, product/package interaction, dispensing, or overall clinical effect or benefit of the product. The procedures outlined in this guide are to be used by assessors that have been specifically screened for sensory and descriptive ability and trained in the evaluation of toothbrushes or toothpaste or both. The procedures described in this guide can be used to guide product development within a manufacturer and communicate information regarding the product to the consumer through the media or on product packaging. 5.2 Additionally, language and ideas from two additional ASTM International sensory guides (Guides E1490 and E2082 ) as well as the Lexicon for Sensory Evaluation: Aroma, Flavor, Texture, and Appearance (DS72-2ND) 4 are used throughout this guide.
