1.1 这种分类涵盖了成对的尺度（参见 无花果。1- 8. )用于分类办公设施可服务性的一个方面，即办公设施满足某些可能的可管理性要求的能力。 （A） 本表所列项目的预期剩余使用寿命应存档，很可能在设施的资产管理计划中。否则，这方面的可用性评级需要专家对每个项目进行判断，并且不能在正常的半天现场访问内完成。如果没有可用信息，则从评级中省略该项，并在评级表上注明。 （B） 对于估计低于图例中给出的临界年数的任何剩余寿命，请勿按比例添加计数。此表中的计数不是滑动比例，例如，给出所有点或没有点。 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《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====== 4.1 该分类中的每个设施评级表（见 无花果。1- 8. )提供了一种方法来估计建筑物或设施对一个可用性主题的可用性水平，并将该水平与任何其他建筑物或设施的水平进行比较。 4.2 该分类可用于比较不同建筑物或设施满足特定可用性要求的程度。尽管存在位置、结构、机械系统、年龄和建筑形状等差异，但它仍然适用。 4.3 该分类可用于估计单个办公设施或一组办公设施内的可用性与目标或需求的差异量。 4.4 该分类可用于估计以下各项: 4.4.1 现有设施对其当前用途以外的用途的可用性。 4.4.2 已规划但尚未建造的设施的可用性（潜力）。 4.4.3 计划改建的设施的可用性（潜力）。 4.5 使用该分类不会导致建筑物评估或诊断。建筑评估或诊断通常需要建筑工程或技术方面的专业知识，以及仪器、工具或测量的使用。 4.6 该分类仅适用于建筑结构或其部分的设施。 （虽然该分类可能有助于评估非建筑设施的可用性，但此类设施不在该分类的范围内。） 4.7 该分类不适用于监管目的，也不适用于火灾危险评估或火灾风险评估。

1.1 This classification covers pairs of scales (see Figs. 1- 8 ) for classifying an aspect of the serviceability of an office facility, that is, the capability of an office facility to meet certain possible requirements for manageability. (A) The anticipated remaining service life on the items listed in this table should be on file, likely in an asset management plan for the facility. Otherwise, rating on this aspect of serviceability requires expert judgement on each item, and cannot be completed within a normal half-day site visit. If information is not available, then omit this item from the rating, and note that on the rating form. (B) Do not add pro rata counts for any remaining life that is estimated to be less than the threshold years given in the legend. The count in this table is not a sliding scale, for example, give all points or no points. 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 ====== 4.1 Each facility rating scale in this classification (see Figs. 1- 8 ) provides a means to estimate the level of serviceability of a building or facility for one topic of serviceability, and to compare that level against the level of any other building or facility. 4.2 This classification can be used for comparing how well different buildings or facilities meet a particular requirement for serviceability. It is applicable despite differences such aslocation, structure, mechanical systems, age, and building shape. 4.3 This classification can be used to estimate the amount of variance of serviceability from target or from requirement, for a single office facility, or within a group of office facilities. 4.4 This classification can be used to estimate the following: 4.4.1 Serviceability of an existing facility for uses other than its present use. 4.4.2 Serviceability (potential) of a facility that has been planned but not yet built. 4.4.3 Serviceability (potential) of a facility for which a remodeling has been planned. 4.5 Use of this classification does not result in building evaluation or diagnosis. Building evaluation or diagnosis generally requires a special expertise in building engineering or technology, and the use of instruments, tools, or measurements. 4.6 This classification applies only to facilities that are building constructions, or parts thereof. (While this classification may be useful in rating the serviceability of facilities that are not building constructions, such facilities are outside the scope of this classification.) 4.7 This classification is not intended for, and is not suitable for, use for regulatory purposes, nor for fire hazard assessment nor fire risk assessment.
