Hose, Tubing & Fluid Conveyance Products calculator

Warranty Exposure Calculator

Assess warranty exposure risk for a hose or tubing assembly product. Score the severity of a hose failure, the likelihood of occurrence, and the difficulty of detecting the failure before shipment. The weighted score lets you compare and prioritize risks across products or failure modes.

What this calculator does

  • Score warranty exposure risk for a hose or tubing assembly product from failure severity, occurrence likelihood, and detection difficulty.
  • Use it when reviewing warranty risk for a hose assembly product, ranking claims by risk priority, or deciding whether a design or process change is justified.
  • Produces a weighted warranty exposure score from failure severity, occurrence, and detection difficulty.

Formula used

  • Warranty exposure score = severity x 0.40 + occurrence x 0.35 + detection x 0.25

Inputs explained

  • Failure severity score: Score 1 to 10 for the consequence of the hose failure mode. Safety failures or fluid spills score higher.
  • Failure occurrence score: Score 1 to 10 for how frequently this failure mode occurs based on production history or application severity.
  • Detection difficulty score: Score 1 to 10 for how hard the failure mode is to detect before shipment. High score means controls are unlikely to catch it.

How to use the result

  • Use it to rank warranty exposure across hose assembly products or failure modes.
  • It is a relative ranking tool. It does not quantify warranty dollar exposure or replace a full FMEA process.

Common questions

  • What is the Warranty Exposure calculator for? It scores warranty exposure risk for a hose assembly from severity, occurrence, and detection difficulty so you can rank and prioritize warranty risks.
  • What numbers do I need before using it? Score each dimension 1 to 10 using your FMEA calibration scale for the specific hose assembly failure mode being evaluated.
  • How should I use the result? Use the score to rank warranty risks across products, decide whether controls are adequate, and prioritize corrective actions.
  • When is the result only an estimate? It is a relative ranking estimate. Actual warranty exposure depends on field conditions and application severity not captured by this score.
