ECICM04 Analyse the data from condition monitoring activities

Business Sectors (Suites): Condition Monitoring
Developed by: ECITB
Approved on: 26 Jan 2022


This standard is about the analysis of data relating to the monitored component or asset.

You will need to be able to collate all relevant  data and analyse this against the base data for the component or asset specification, and other relevant standards and information in order to identify any faults or variations in the component or asset’s condition whilst adhering to health and safety legislation, regulations and safe working practices.

In the context of this standard, your responsibility is to interpret and work within given specifications, selecting techniques and making variations to achieve the best possible result. In some cases, you may still be expected to refer to others for final authorisation, even though you remain responsible for identifying and implementing decisions.

Who this standard is for:
This standard is for condition monitoring practitioners.

Performance criteria

You must be able to:

  1. work safely at all times, complying with health, safety, environmental and other relevant legislation, regulations, guidelines and local rules or procedures
  2. ensure that the work environment, material, tools and condition monitoring equipment and instrumentation are suitably prepared for the work activities to be undertaken
  3. obtain and interpret the required information and specifications using drawings and other relevant sources
  4. ensure that the sample or data is of sufficient quality and integrity to conduct the analysis
  5. analyse the sample or data using approved methods and procedures
  6. compare current data with base line data or that from previous monitoring activities, trends and specifications
  7. review the results of the monitoring and collect further samples or data if necessary
  8. dismantle component(s) to assist problem diagnosis where required
  9. determine the correct use, care and security of relevant tools and equipment you use
  10. identify principal cause(s) of the problem and recommend corrective or operational actions
  11. record and store information to maintain the integrity of the sample or data
  12. ensure the work area is reinstated deal promptly and effectively with problems within your control and report those that have been and those that cannot be solved

Knowledge and Understanding

You need to know and understand:

  1. relevant legislative, regulatory and local requirements or procedures and safe working practices
  2. preparation and reinstatement requirements in respect of the work area, material, and equipment, and the possible consequences of incorrect actions in these area
  3. relevant engineering drawings, related specifications, quality standards and manufacturers' information
  4. analysis methods and techniques
  5. testing methods and procedures
  6. disassembly techniques
  7. your responsibilities for ensuring care and security of tools and equipment usedyour responsibilities with regard to reporting lines and procedures in your working environment


Scope Performance

Scope Knowledge





A Work environment could include:

  • engineering construction sites
  • controlled operations
  • offshore installations
  • maintenance sites
  • nuclear sites
  • repair sites

A Work environment may be in open or restricted spaces:  

  • at height 
  • confined spaces
  • control rooms
  • controlled operational and offshore installations
  • designated work areas
  • explosive atmospheres
  • existing plants and structures
  • fabrication workshops 
  • in plant rooms
  • inside structures, systems and plant
  • on access structures (scaffold)
  • on open structures
  • onshore and offshore installations
  • shafts
  • shipyards
  • tunnels

Work area is reinstated could include:

  • returning the work area to a safe condition
  • removing barriers 
  • sweeping up
  • correctly disposing of waste materials
  • storing re-usable materials, consumables and equipment in accordance with appropriate procedures
  • completing all necessary documentation

Analysis methods and techniques could include:

  • assessment against standards and specifications
  • chemical and physical analysis
  • comparison with historical data
  • comparison against published acceptance criteria
  • parity checks
  • pattern recognition
  • pre and post data processing
  • reference against norms
  • statistical
  • time, domain and frequency analysis
  • trend analysis

Engineering drawings and related specifications:

An engineering drawing is a type of technical drawing that is used to convey information about an item for construction, maintenance or fault-finding       purposes and can define test-points used for condition monitoring


Engineering specifications can include manufacturer's instructions or information from alternative sources that allows you to determine operational parameters of a device
