A number in parentheses indicates the year of last reapproval. A superscript epsilon indicates an editorial change since the last revision or reapproval. V1188 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.

Since specific gravity has no units, it must be converted to density when this v1188 of measurement is required. This conversion is made by multiplying the specific gravity at a given temperature by the density of water at the same temperature.

It shall be equipped with a suitable apparatus to permit weighing the specimen while it is suspended in water. The asm shall conform to Specification D as a class GP2 balance.


For example, a sensitivity of 0. Current edition approved July 1, Originally approved in No further reproductions authorized. Additionally, a minimum of one foam pad with a size approximately equal to the top surface dimensions of the sample shall be on hand.

Field samples should be obtained in accordance with Practice D Pavement specimens shall be taken from pavements with a core drill, diamond, or carborundrum saw, or other suitable means, c1188 accordance with Practice D Store specimens in a safe, cool place.

When any of these materials are visually evident, they shall be removed in accordance with 6. Designate this as mass A. Take care not atsm create holes in the film. Use another specimen of the same size xstm press down on top of the foam.

This will eliminate the air pockets from both surfaces. Take care not to damage the sample. There should be a minimum of 15 m approximately 0.

Grasp the film at the ends and stretch out to about m 16 in. Designate this mass as D. Designate this mass as E. The specific gravity is:. A constant mass is defined d1818 less than a 0.

Designate this oven-dry mass as Edry. The mass of the moisture, Astn is:. The mass of the moisture is then subtracted from any determination of mass in the following sections.
