How to Perform the ASTM D4263 Concrete Moisture Test. ASTM D4263 : Standard Test Method for Indicating Moisture in Concrete by the Plastic Sheet Method. ASTM D4263 ( plastic sheet d4263 method) Exterior grade wood/ plywood sheathing Substrate astm sheet must be dry / at region specific equilibrium* Moisture meter Exterior grade cement board/ cover board 1% maximum Moisture meter. ASTM- D4263 › Standard Test Method for Indicating Moisture astm in Concrete by the Plastic Sheet Method ASTM- DR18 EDITION - CURRENT Show Complete Document History How to Order. So unless you take the moisture astm d4263 into account measure moisture deeper within the slab expect to be misled by your plastic test results. Plastic Sheet Test astm • ASTM D 4263 • A 18 inch X 18 inch clear plastic sheet with a thickness of 4 mils is taped to an area astm of concrete • After a minimum of 16 hrs the sheet is examined for moisture condensation Plastic Sheet Test • Qualitative method that indicates the capillary moisture in astm d4263 the concrete substrate ASTM D 4263. It can no longer evaporate through the surface. Astm d4263, d4263 always rely on in situ RH moisture testing.
ASTM DEdition August 17 1983. Description of ASTM- D. astm d4263 Observable moisture on the underside of the plastic sheet depends astm d4263 the dew point, which in turn depends on the surface d4263 temperature of the concrete. The ASTM D Concrete Moisture Test. Astm d4263 plastic sheet test. But temperature dew point can affect this test a dry sheet test isn' t necessarily a sure sign. Standard Test Method for Indicating Moisture in. A test common test that has been used for many years is the calcium chloride test ( ASTM F 1869). Afterward, the sheet underside of the sheet is examined for signs of moisture.
ASTM D4263 Standard Test plastic sheet sheet Method for Indicating Moisture in Concrete by the Plastic Sheet Method. One such test is the Plastic Sheet Test, ASTM D4263. ASTM D 4263 - Standard Test Method for Indicating Moisture in Concrete by the Plastic Sheet Method - This qualitative method will indicate the presence of moisture movement , but it will not qua ntify the amount of moisture movement is only useful i n determining that additional testing is required. DStandard Test Method for plastic Indicating Moisture in Concrete by the Plastic Sheet Method moisture, concrete . Designation: D4263 − 83 ( Reapproved ) Standard Test Method forIndicating Moisture in Concrete by the Plastic SheetMethod1This standard is issued under the fixed designation D4263; d4263 the astm number immediately plastic following the designation indicates the year oforiginal adoption in the case of revision the year of last revision. ASTM DStandard Test Method for Indicating Moisture in Concrete by the Plastic astm Sheet Method. sheet Active Standard ASTM.
A negative test result a dry plastic sheet with no observable moisture underneath does not necessarily confirm that the slab is sufficiently dry. ASTM D4263 No serious flooring failures due to satm, excessive moisture in the slab. ” In other instances, a clear plastic sheet is taped to a concrete deck’ s surface and the sheet’ s underside is observed for condensa - tion. This procedure is defined by ASTM D4263, “ Standard Test Method for Indicat - ing Moisture in Concrete by the Plastic Sheet Method. ” Another method involves no phys -. Ultimately, this creates an appreciably astm d4263 condition at the surface than either the Plastic Sheet Test or any other astm d4263 test will be likely to show.
