Historical Standard: ASTM D4189-95(2002) Standard Test Method for Silt Density Index (SDI) of Water
SUPERSEDED (see Active link, below)
ASTM D4189
1. Scope
1.1 This test method covers the determination of the silt density index (SDI) of water. This test method can be used to indicate the quantity of particulate matter in water and is applicable to relatively low (1.0 NTU) turbidity waters such as well water, filtered water, or clarified effluent samples. Since the size, shape, and nature of particulate matter in water may vary, this test method is not an absolute measurement of the quantity of particulate matter.
1.2 This test method is not applicable for reagent grade water Types I, II, and III of Specification D 1193, or effluents from most reverse osmosis and ultrafiltration systems.
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.
