How to make ICML-aligned lubrication executable at the lubrication point

Optimum Reference State (ORS): from definition to control

Many plants have lubrication standards, routes and audits, yet failures repeat because “correct lubrication” is still interpreted differently at the point of application. ORS (Optimum Reference State) helps close that gap by defining the agreed, measurable “in control” condition per lubrication point.
Lubrication can be treated as a control discipline: define what “in control” looks like, execute it repeatably, and verify stability through trends.

What ORS changes in practice

ORS shifts lubrication from task completion to predictable performance:

  • fewer repeat failures driven by contamination, dosing variation and drifting mechanical basics
  • less firefighting through stable trends (temperature, vibration, leakage)
  • clearer decisions: acceptable versus deviation, with defined corrective actions

ORS only works when it is executed repeatably and verified over time, with corrective action to prevent drift and maintain stable operating trends.

ORS, ICML-aligned management and the Interflon approach

ORS does not replace ICML 55 or similar frameworks. It is the execution layer that makes ICML-aligned intent executable on the shop floor through reference states, standard work and verification.
ORS is tool-independent, but it depends on implementation quality. Control requires: 

  • point data (lubricant, dose, method, interval, purge/relief logic)
  • defined acceptance criteria (“clean” and “acceptable” per site)
  • verification checks linked to dominant disturbances

Interflon’s role is to operationalise ORS without reinventing methods and check logic. Technical Advisors translate ORS into point data, ORS cards, routes and verification routines, and support stabilisation of performance trends. Where scale or evidence capture is a constraint, digital workflows (for example Lubrication Management Software) can support consistent execution and verification.

Minimum verification set

A full condition monitoring programme is not required to start. Use a limited set of checks aligned with the main failure drivers:

  • task compliance (performed as specified)
  • dosing logic (defined method/tool, not “by feel”)
  • visual signals: leakage, dirt build-up, discolouration, purge behaviour
  • relief/drain status: opened where applicable, point left clean
  • temperature trend versus baseline
  • rapid noise or vibration deviation check
  • contamination risk: seal condition, housekeeping, washdown exposure

Where tools are available, verification can be extended with vibration analysis, oil or particle measurement, thermography or ultrasound.

The five ORS pillars

  1. Lubricant selection and film robustness
    Select for load, speed, temperature and environment to maintain a stable lubricating film.
  2. Contamination control
    Prevent ingress, protect lubrication points during work, and control residues after cleaning.
  3. Execution to design intent
    Define dose, method and interval. Manage purge or relief paths correctly. Where no purge path exists, apply micro-dosing and verify by trends — avoid “pump until purge” where design does not support it.
  4. Mechanical integrity
    Alignment, fits and installation quality define contact stress and film margin. ORS assumes mechanical basics are within agreed tolerances (or deviations are explicitly managed).
  5. Process discipline and standardisation
    Tagging, fixed routes, one instruction per task and 6S keep execution stable over time.

Practical considerations for grease-lubricated assets

The following factors influence whether the defined ORS can be achieved in practice:

Run condition and utilisation rate
For rotating assets, grease delivery should consider whether the machine is running and how often it operates. This is especially relevant for single-point or central lubrication systems to reduce the risk of over-supply during standstill.

Correct pre-fill and clean preparation
ORS assumes a valid starting condition. Clean handling and correct initial grease fill (pre-fill) are required to establish a reliable baseline for verification.

Purge paths and seal design
The ability to purge used grease depends on purge paths and seal configuration. The ORS must reflect the actual purge or relief capability of the lubrication point.

Common ORS mistakes

  • treating ORS as “more lubrication” instead of correct dose and method
  • starting without a baseline, so no trend comparison exists
  • no standard work, making execution person-dependent
  • addressing contamination only when visible
  • treating cleaning and lubrication as separate processes
  • ignoring alignment and installation effects on film formation

ORS in 30–60 days

A pragmatic starting approach:

  1. Select scope using Pareto (top disruption assets).
  2. Baseline current practice and signals.
  3. Create ORS cards per point: lubricant, dose, method, interval, purge logic and acceptance criteria.
  4. Embed standard work: tagging, routes, one instruction per task.
  5. Verify using the minimum set and a simple trend log.
  6. Stabilise first, then expand scope.

Defining ORS is typically straightforward. Sustaining ORS requires structure, verification discipline and follow-up, because drift returns through contamination, dosing creep, cleaning residues and changing operating conditions.

Mini case:

Grease re-lubrication caused leakage and post-lube temperature rise until ORS execution rules and verification checks were added.

Conclusion

If you want to implement ORS without reinventing methods and check logic, a Technical Advisor can help define ORS for critical lubrication points, translate it into standard work and verification, and support trend stabilisation.

 

Frequently Asked Questions

A baseline describes the current situation: what is done today and where deviations exist. ORS is the reference state: what “in control” looks like and how it is embedded in tasks and routes. The baseline is used to define ORS per asset class and prioritise improvement actions.

Look for trends and repeat issues: rising temperature, leakage, dirt build-up, abnormal grease purge, discolouration, abnormal noise, higher vibration or early component failure. These typically indicate contamination, incorrect dosing or selection, or a mechanical condition issue.

Start with a small scope: the points that create the most work and disruption. Create one ORS card per point and standardise one route with one checklist. Stabilise execution first. Then expand with additional measurements or support.

Yes. Alignment and installation influence contact stress and film formation directly. Small deviations increase local stresses and reduce effective film thickness. A correct lubricant can still fail if the mechanical baseline is not controlled. ORS therefore extends beyond lubrication alone.

Cleaning and washdown affect contamination, seals and film presence. ORS requires alignment between cleaning and lubrication: correct agents and method, protection of lubrication points, prevention of residues and recontamination, and adjustment of method or interval where needed.
