Oil-Analysis Governance: govern CMMS linkage against the exact compressor, lubricant and sampling context. Record asset tag/model/serial, fluid identity, service hours, sample point, machine state, sample date, laboratory method, previous trend, maintenance/top-up history, interpretation confidence and action. Never treat a generic laboratory flag as a universal compressor limit. Confirm abnormal results through trend, resampling, related condition data or physical inspection as appropriate before major maintenance decisions.

147 — Work-Order Linkage

Oil-Analysis Governance: govern work-order linkage against the exact compressor, lubricant and sampling context. Record asset tag/model/serial, fluid identity, service hours, sample point, machine state, sample date, laboratory method, previous trend, maintenance/top-up history, interpretation confidence and action. Never treat a generic laboratory flag as a universal compressor limit. Confirm abnormal results through trend, resampling, related condition data or physical inspection as appropriate before major maintenance decisions.

148 — As-Found Confirmation

Oil-Analysis Governance: govern as-found confirmation against the exact compressor, lubricant and sampling context. Record asset tag/model/serial, fluid identity, service hours, sample point, machine state, sample date, laboratory method, previous trend, maintenance/top-up history, interpretation confidence and action. Never treat a generic laboratory flag as a universal compressor limit. Confirm abnormal results through trend, resampling, related condition data or physical inspection as appropriate before major maintenance decisions.

Compressed-Air Lubricant, Oil Analysis & Fluid-Condition Engineering

Oil analysis is not a pass/fail lab report. it is a trending discipline that connects fluid condition, contamination, wear, operating context and maintenance action
