(Test Method)Standard Test Method for Moisture in Mineral Aggregate Used on Built-Up Roofs
Standard Test Method for Moisture in Mineral Aggregate Used on Built-Up Roofs
SIGNIFICANCE AND USE
This test method measures the moisture in mineral aggregate required by Specification D1863.
SCOPE
1.1 This test method covers the determination of moisture in mineral aggregate for use on built-up roofs.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Summary of Test Method
3.1 The aggregate is dried to constant mass in a 110°C (230°F)[230°F] oven. The mass percent moisture is calculated as the
loss in mass based on the mass of the oven dry aggregate.
4. Significance and Use
4.1 This test method measures the moisture in mineral aggregate required by Specification D1863.
5. Apparatus
5.1 Balance, 1000-g (2.2-lb)[2.2-lb] capacity, sensitive to 0.01% of the capacity.
5.2 Oven, large enough to hold the sample and capable of maintaining a temperature of 110°C (230°F)[230°F] 61%.
5.3 Sample Container, consisting of an evaporating dish or similar shallow container.
6. Sampling
6.1 Sample aggregates received in bulk in accordance with Practice D75.
6.2 For aggregates received in bags or small containers, select a number of bags or small containers at random, equivalent to
the cube root of the total number in the shipment.
