1.1 This test method provides an indirect measurement of the viscosity of construction slurries using a funnel (Marsh Funnel) and a graduated cup with specific volume marks. This test method provides an indicator of the viscosity on a routine basis. This test method has been modified from the API Recommended Practice 13B-1.

1.2 The result determined using the method is referred to as the Marsh Funnel Viscosity. The Marsh Funnel Viscosity is an index property and is not an actual measurement of viscosity.

1.3 This test can be performed in the laboratory or in the field to assess the Marsh Funnel Viscosity of a slurry for quality control purposes.

1.4 Units—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 nonconformance with the standard.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
