ISO/TR 16840-9:2015旨在指导用户执行与界面压力图（IPM）临床应用直接相关的任务，或与综合轮椅座椅评估中的使用协同作用的任务。 ISO/TR 16840-9:2015不包括临床评估过程的其他方面（如病史），也不包括评估可能产生的处方或治疗过程。这些指南并不意味着在完整评估的背景下替代临床推理和判断。 ISO/TR 16840-9:2015是指座椅场景中IPM体验的最新水平。例如，所涵盖的大多数原则可以外推到全身（在床上）或足部评估。

ISO/TR 16840-9:2015 has been produced to guide users in the performance of the tasks that are directly involved in the clinical use of interface pressure mapping (IPM) or are synergistic with its use in a comprehensive wheelchair seating evaluation. ISO/TR 16840-9:2015 does not cover other aspects of the clinical assessment process (e.g. taking a medical history), nor the prescription or treatment process which might arise from an assessment. These guidelines are not meant to be a substitute for clinical reasoning and judgement within the context of a complete assessment. ISO/TR 16840-9:2015 refers to the state of the art of IPM experiences in a seating scenario. Most of the principles covered can be extrapolated to whole body (in bed) or to foot assessments, for example.
