The standard RILEM tube can hold

The specimens are to be placed in ambient temperature ( and moderate relative humidity (percent) and are monitored for evaporation facilitated by sunlight or wind; they are recorded at one-, five-, and 10-minute intervals. At the conclusion of the test, the droplets are classified as standing, partially absorbed, totally absorbed, or dry. Additional testing methods should be implemented to further evaluate failed droplet tests.*
Commencement of a droplet test on a concrete masonry unit (CMU) containing integral water repellent.
After fi ve minutes, the originally beaded droplet has been partially rcs data absorbed into the CMU containing integral water repellent.
After five minutes, the originally beaded droplet has been partially absorbed into the CMU containing integral water repellent.
RILEM tube testing
5 ml (0.17 oz.) of water, which correlates with the static pressure of a 158-kph (98-mph) wind-driven rain. The short RILEM tube was developed for porous materials that are unable to pass a standard RILEM test. A short RILEM tube (approximately 2 ml [0.06 oz.] of water) correlates with a 97-kph (60-mph) wind-driven rain.
