1.1 本标准实施规程描述了评估住宅室内空气质量（IAQ）问题的程序。 1.2 该实践主要解决单户独立和附属（例如联排别墅或复式设计）住宅中遇到的室内空气品质问题。对于低层和高层多户住宅，如公寓和公寓，也提供了有限的指导。 1.3 室内空气品质评估程序包括与房主或居民的访谈（包括电话访谈和面对面会议）和现场调查（包括走查、评估和测量）。为了应用的实用性，这些程序分为三个独立的阶段，可能会在一次或多次实地考察中发生。 1.4 本标准实施规程中描述的程序旨在识别导致室内空气品质问题或担忧的潜在原因。 这些发现可以作为建议纠正措施的基础。本标准惯例未描述问题解决或纠正措施，本标准无意评估纠正措施的影响。 1.5 本规程描述了表征室内空气的途径，但使用本规程并不保证调查员能够识别或解决以下一个或多个原因引起的室内空气质量投诉: (1) 室内空气中来源和污染物的多样性； (2) 其他可能影响居住者感知和接受室内空气质量的因素，如空气温度、湿度、噪音、照明和心理压力； (3) 人群中的易感性范围。 1.6 执行本标准中给出的程序要求研究人员（或调查团队）在以下几个方面具有足够的背景: 室内空气品质的一般原则；面试技巧；建筑设计和施工实践；对加热和冷却系统及电器有基本了解；室内空气品质测量设备的使用；室内空气品质数据的解释；撰写技术报告。 1.7 虽然本标准实践中描述的许多要素可能有助于室内空气品质调查人员的培训，但不应将其作为指定或进行此类培训的唯一依据。 1.8 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。 有关其他安全预防信息，请参阅第节 6. . 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 基于室内空气质量的投诉和问题包括不适/医疗症状和不可接受的室内环境条件，例如住宅建筑中存在的气味。室内空气品质投诉和问题的发生频率可能未知。 5.2 室内空气品质问题的表征及其根本原因的识别需要对室内空气和环境、其使用者和潜在污染源进行系统的观察和测量。本实践为室内空气品质问题的调查提供了背景和程序。 5.3 如果住宅不是业主自用的，通常需要获得正式许可才能进入房产的某些区域，并收集室内空气质量调查所必需的信息。 5.4 本实践中描述的分步和分阶段方法允许进行与问题性质和调查可用资源水平相称的调查。

1.1 This standard practice describes procedures for evaluating indoor air quality (IAQ) concerns in residential buildings. 1.2 The practice primarily addresses IAQ concerns encountered in single-family detached and attached (for example, townhouse or duplex design) residential buildings. Limited guidance is also provided for low- and high-rise multifamily dwellings, such as condominiums and apartments. 1.3 The IAQ evaluation procedures are comprised of interviews with the homeowner or resident(s) (including telephone interviews and face-to-face meetings) and on-site investigations (including walk-through, assessment, and measurements). For application practicality, these procedures are divided into three separate phases, which may occur over one or more site visits. 1.4 The procedures described in this standard practice are aimed at identifying potential causes contributing to an IAQ issue or concern. Such findings can be the basis for recommending corrective measures. This standard practice does not describe problem resolution or corrective measures, and the standard is not intended to evaluate the impact of corrective measures. 1.5 This practice describes a pathway for characterizing indoor air, though using this practice does not guarantee that an investigator will be able to identify or resolve an IAQ complaint for one or more of the following reasons: (1) the diversity of sources and contaminants in indoor air; (2) other factors that may affect occupant perception and acceptance of indoor air quality, such as air temperature, humidity, noise, lighting, and psychological stress; (3) the range of susceptibility in the population. 1.6 Implementation of procedures given in this standard requires the investigator (or investigative team) to have adequate background in several areas: general principles of IAQ; interviewing techniques; building design and construction practices; basic understanding of heating and cooling systems and appliances; use of IAQ measurement equipment; interpretation of IAQ data; and technical report writing. 1.7 Although many elements described in this standard practice may be useful in training of IAQ investigators, it should not be used as the sole basis for specifying or conducting such training. 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. For additional safety precautionary information, see Section 6 . 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 IAQ-based complaints and problems include discomfort/medical symptoms and unacceptable indoor environmental conditions such as odors that exist in residential buildings. The frequency of the occurrence of IAQ complaints and problems may be unknown. 5.2 Characterization of IAQ concerns and identification of their underlying causes require systematic observations and measurements of the indoor air and environment, its occupants and potential contaminant sources. This practice provides background and procedures for the investigation of IAQ concerns. 5.3 Where the dwelling is not owner-occupied, formal permission to access certain areas of the property and to collect information essential to the IAQ investigation is often required. 5.4 The stepwise and phased approach described in this practice allows for an investigation that is commensurate with the nature of the problem and the level of resources available for the investigation.
