| Component | Individually identifiable part of an object consisting of one or more elements, designed to provide a specific function for the object e.g. deck, installations, foundations. |
| Condition | Limitations, deficiencies or inadequacies (or lack thereof) which can be identified by means of condition survey and are related to ability a structure to meet specified performance requirements. |
| Condition assessment | A process of reviewing information gathered about the current condition of a structure, its components and/or elements, its service environment and general circumstances, allowing a prognosis to be made of future condition, taking account of active deterioration mechanisms and, if appropriate, predictions of potential future damage. |
| Condition control | The overall process for safeguarding the condition of a structure during its lifetime, involving condition survey, structural performance assessment and evaluation, decision-making for life-cycle management activities and interventions, performed as a part of the through-life management |
| Condition Survey | The process of acquiring information related to the current condition of a structure, conducted with the aim of recognizing important limitations, defects and deterioration relevant for the ability of a structure to meet specified performance requirements (e.g. appearance, functionality and structural performance requirements1
- 1 Condition survey would also seek to gain an understanding of the (previous) circumstances which have led to the development of that state, together with the associated mechanisms causing damage or deterioration
|
| Condition threshold | A boundary defined to compare different measurable characteristic of a structural components and/or structural members, which is a measure of the probability that the component and/or structural members will not meet specific performance requirements within a specific period of time. |
| Condition-based maintenance (CBM) | Preventive maintenance which includes a combination of condition monitoring and/or inspection and/or testing, analysis and the ensuing maintenance actions, and entails prescribed criteria related to one (or more) condition thresholds to enable decisions about interventions based on physical evidence that exceedance of the condition threshold(s) is occurring or is about to occur. |
| Conformity | Fulfilment of specified requirement |
| Corrective maintenance | Maintenance carried out after fault recognition and intended to put an item into a state in which it can perform a required function at a required performance level. |
