đ Why More Manufacturers Are Approving ASTM 2659 Impedance Meters for Moisture Testing
One trend that keeps accelerating: manufacturers are explicitly calling out ASTM F2659 electrical impedance meters as approved tools for moisture evaluation. This is a big shift from a few years ago, when these meters were often treated as âscreening tools only.â Whatâs driving it? â
Nonâdestructive testing Manufacturers want moisture data without drilling, patching, or damaging assembliesâespecially in finished or occupied spaces. â
Speed + coverage Impedance meters allow technicians to scan large areas quickly and identify moisture patterns, not just pointâinâtime readings. â
Repeatability ASTM 2659 provides a standardized method, which gives manufacturers confidence in consistency across jobs, techs, and regions. â
Better decisionâmaking Instead of guessing where moisture might be, manufacturers can now require documented scans before remediation, flooring installs, or warranty decisions. What this means for contractors & inspectors: ⢠If youâre not using an ASTM 2659âcompliant meter, you may already be behind manufacturer expectations ⢠Documentation from impedance scans is becoming more defensible ⢠âApproved tool listsâ are expandingâand meters that meet ASTM 2659 are showing up more often Important note: Impedance meters still donât replace inâsitu probes or RH testing where requiredâbut manufacturers are increasingly recognizing them as a legitimate, primary assessment tool for many applications. To name a few: 1. Cali Floors 2. Trafficmaster 3. Artisan Hardwoods 4.Tarkett(qualitative purposes) 5.Sika đŹ Curious: Which manufacturers have you seen specifically call out ASTM 2659 meters in their documentation? And how has that changed the way you test or report moisture?
