Environmental components considered include thermal, visual, air quality, acoustic and vibration. This International Standard does not standardise particular scales, it provides the principles that will allow users to construct appropriate scales for their application. This International Standard does not present principles of surveys (see Note 1) or questionnaire design. However, the scales that are developed using this standard may be incorporated into surveys or questionnaires. NOTE 1 – Environmental surveys are described in ISO 28802, (2012). ISO 28802, (2012) includes scales that are complementary to, and based upon, the principles of scale construction that are described in this international standard.
