Steps
Explain that ASTM F2659 is a non-destructive electronic moisture meter guide for comparative (relative) moisture readings in the top ~1 inch of concrete/gypsum/anhydrite slabs and screeds
Emphasize that F2659 explicitly states it does NOT provide quantitative results suitable as the basis for accepting a floor for installation — the standard's own scope points to F1869 or F2170 for quantitative, spec-grade determinations
Position electronic moisture meters as a fast qualitative screening tool (e.g., to decide where to place RH probes or flag suspect areas), not a substitute for a quantitative pass/fail test
Recommend RH probes (F2170) as the current industry-preferred quantitative method for most slabs, noting CaCl (F1869) is excluded for lightweight concrete
Direct the requester to the flooring/adhesive manufacturer's written specification to confirm which test method(s) are contractually required before relying on meter readings alone
Known gotchas
Do not present a pinless/electronic meter reading as equivalent to or a legal substitute for an F1869 or F2170 quantitative result — ASTM's own guide language says otherwise
Meter readings are comparative/relative, not absolute moisture percentages, despite often being displayed as a number
Many warranty and spec disputes hinge on which specific test method was contractually required — confirm before testing, not after
