What this standard is for
Where it is used
This site implements it: Spray Rating Decay & Heat Reactivation (/calculators/water-repellency-spray-rating/) does the arithmetic this standard specifies.
What to watch for
The publisher lists this edition as withdrawn. A laboratory cannot report to a withdrawn method, so a specification still naming it needs a live replacement agreed before testing rather than after.
