1.1.This method covers the determination of the resistance of concrete specimens to the penetration of chloride ion.

It is intended for use in determining the effects of variations in the properties of concrete on the resistance of the concrete to chloride ion penetration.

Variations in the concrete may include, but are not limited to, changes in the cement type and content, water-cement ratio, aggregate type and proportions, admixtures, treatments, curing, and consolidation.

This test method is not intended to provide a quantitative measure of the length of service that may be expected from a specific type of concrete.

1.2. The values stated in SI units are to be regarded as the preferred standard.


2.1.The specimens for use in this test shall be slabs made and cured in accordance with the applicable requirements ofR  39, Making and Curing Concrete Test Specimens in the Laboratory.

Note 1-This   method contemplates the use ofa  minimum of four specimens for each evaluation with each slab not less than 75 mm (3 in.) thick and a minimum surface area of 17,500 mrrr’ (28 in.”),
