1.1 本指南提供了针对触发器硬表面清洁剂感官评估的指南。它涵盖了制备无孔表面的程序，旨在测量触发产品的一个或所有方面:包装、应用、性能和使用后性能，重点关注视觉、触觉、香味、性能和包装人体工程学。它适用于评估员、训练有素的评估员和消费者。 1.2 本无孔硬质表面制备指南旨在关注表面制备和评估，而非面板选择、培训或开发。 1.3 读者应意识到，在准备表面以及培养和培训评估员时，需要良好的感官实践。 1.4 研究人员负责确定最合适的测试设计，并使用适当的统计工具解决该实验设计。 1.5 由于本指南的预期用途是为喷涂触发式硬表面清洁剂的不同方面的介绍和测量提供指导，因此本指南可能无法准确代表可能使用喷涂触发式硬质表面清洁剂时的所有可能土壤和表面。 1.6 本指南提供了建议的程序，并不意味着排除可有效用于提供相同结果的替代程序。 1.7 以国际单位或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不完全相等；因此，每个系统应独立于其他系统使用。结合两个系统的值可能会导致不符合标准。当实践中未使用英寸-磅单位时，仅以国际单位表示数值。 1.8 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。 1.9 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 本指南中概述的方法可用于定性和定量评估无孔表面触发式硬表面家用清洁产品的感官特性和性能。 5.2 这些方法适用于描述性分析，也可能适用于消费者接受度研究。 5.3 本指南提供了硬表面清洁剂的包装、应用、性能、使用后和香味方面的评估程序。根据测试目标，可以使用所有或部分这些措施。 5.4 本指南用于产品配方、新产品开发和质量控制问题中的产品研究指导。 5.5 本指南是一份信息概要或一系列选项，不建议具体的行动方案。本指南不用于索赔证明，因为它没有经过验证测试。 5.6 本指南适用于熟悉这些程序并具有感官评估经验的个人。 建议这些人在开发和培训描述性小组方面具有一定经验，或在有经验的感官专业人员的监督下工作。 5.7 本指南可能涉及危险材料。本指南并没有说明与使用相关的所有安全问题。本指南的用户有责任制定适当的安全和健康做法，并在使用前确定限制的适用性。

1.1 This guide presents guidelines specific to the sensory evaluation of trigger hard surface cleaners. It covers the procedure for preparing a nonporous surface with the intent to measure one or all of the various aspects of a trigger product: package, application, performance, and after-use properties, with focus on visual, tactile, fragrance, performance, and package ergonomics. It is applicable for use with assessors, highly trained assessors, and consumers. 1.2 This guide for preparing nonporous hard surfaces is intended to focus on surface preparation and evaluation, not on panel selection, training, or development. 1.3 The reader should be aware that good sensory practices are required when preparing the surfaces, and in developing and training the assessors. 1.4 The researcher is responsible for identifying the most appropriate test design and using the appropriate statistical tool to address that experimental design. 1.5 Since this guide's intended use is to provide direction on the presentation and measurement of the different aspects of spray trigger hard surface cleaners, this guide may not accurately represent all possible soils and surfaces where spray trigger hard surface cleaners may be used. 1.6 This guide provides suggested procedures and is not meant to exclude alternate procedures that may be effectively used to provide the same results. 1.7 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Values are stated in only SI units when inch-pound units are not used in practice. 1.8 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. 1.9 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 methods outlined in this guide can be used to qualitatively and quantitatively evaluate the sensory characteristics and performance of trigger hard surface household cleaning products for nonporous surfaces. 5.2 The methods are suited for descriptive analysis and may be adaptable for consumer acceptance research. 5.3 This guide provides the procedure for the evaluation of package, application, performance, after-use and fragrance aspects of hard surface cleaners. Depending on the test objectives, all or some of these measures may be used. 5.4 This guide is designed for use for product research guidance in product formulation, new product development, and quality control issues. 5.5 This guide is a compendium of information or series of options that does not recommend a specific course of action. This guide is not intended for claim substantiation, as it has not been subjected to validation testing. 5.6 This guide is for use by individuals who familiarize themselves with these procedures and who have previous experience with sensory evaluations. It is suggested that the individuals have some experience with developing and training a descriptive panel or work under the supervision of a sensory professional who has. 5.7 This guide might involve hazardous materials. This guide does not claim to address all of the safety problems associated with its use. It is the responsibility of the user of this guide to establish appropriate safety and healthy practices and to determine the applicability of limitations prior to use.
