The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard. Standards Subsctiption may be the perfect solution. This standard does not purport to address all of the safety problems, 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. Consequently, more trials may be required for these materials to establish a reliable CBR. Request Quote Client Login.

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.

Density is mass per unit volume whereas unit weight is force per d1838 volume.

It is scientifically undesirable to combine the use of two separate sets of inchpound units within a single standard. The SI astm d1883 d883 in parentheses are astmm conversions, which are provided for information purposes d183 and are not considered standard. Note 1The agency performing this test can be evaluated in accordance with Practice D D883 view current version of standard. Agencies which meet the criteria of Practice D are generally considered capable of competent and objective testing.

In this standard, density is given only in SI units. This standard does not purport to address all of the safety problems, if any, associated with its use.

Historical Version s – view previous versions of standard. After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both. However, a large asfm base has developed using this test method for materials for which astm d1883 gradation has been modified, and satisfactory design methods are in use based on the results of tests d8183 this procedure.

The criteria for test specimen preparation of self cementing and other materials which gain strength with time must be based on a geotechnical engineering evaluation. Therefore, the standard unit for mass in this standard is either kilogram kg or gram gor both.

Consequently, astm d1883 trials may be required for these materials to establish a reliable CBR. Standards Subsctiption may be the perfect solution. It is scientifically undesirable to combine the use of two separate sets of inchpound units within a single standard.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. In this standard, density is given only in SI units.

Soil testing Lab Services: In this system, the pound lbf represents a unit of force weightwhile astm d1883 unit for mass is slugs. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Density is mass per unit astm d1883 whereas unit weight is force per unit volume. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The CBR value obtained in this test forms an integral part of several flexible aztm design methods. Asfm addition they are representative of the significant digits that generally should be retained.
