(18.6 sq. m), <br />and perform no fewer than three tests in each installation area and with test areas evenly spaced <br />in installation areas. <br />a.Anhydrous Calcium Chloride Test: ASTM F 1869. Proceed with installation only after <br />substrates have maximum moisture-vapor-emission rate of 3 lb of water/1000 sq. ft. <br />(1.36 kg of water/92.9 sq. m) in 24 hours. <br />b.Relative Humidity Test: Using in situ probes, ASTM F 2170. Proceed with installation <br />only after substrates have a maximum 60 percent relative humidity level measurement. <br />c.Perform additional moisture tests recommended in writing by adhesive and carpet <br />manufacturers. Proceed with installation only after substrates pass testing. <br />D.Proceed with installation only after unsatisfactory conditions have been corrected.
