ASTM D6502 Measurement of On-line Integrated Samples of Low Level Suspended Solids and Ionic Solids in Process Water by XRF

Scope: Power plant operators are concerned about corrosion products in particulate and dissolved metals in electricity-producing plants’ steam and water circuits. Corrosion products in the feed water also enter the steam-generating components, which deposit on heat transfer surfaces, lowering the plant’s overall efficiency. A time profile of corrosion product transit is established using more frequent...

ASTM E640 − 06 Preservatives in Water-Containing Cosmetics

Scope: This test method should be performed to establish whether a preservative or preservative system can be utilized to preserve water-containing cosmetics. Routine microbiological procedures are used to determine the antimicrobial activity of preservatives in formulations. Procedure The bacterial cultures are grown on the proper slants using a sterile inoculum.  The development from each culture...

ASTM D698-12 Laboratory Compaction Characteristics of Soil

Scope: ASTM D698-12 standard test method defines procedures for compaction tests to be performed on soil or material. The methods help determine the relationship between moulding water content and dry unit weight of soils or material, known as compaction curve. Soils (materials) having 30% or less mass retained on 19.0 mm sieve qualify to be...

ASTM D7645 Determination of Insecticides in Water by Liquid Chromatography

Scope: The U.S. Environmental Protection Agency (EPA) has identified the N-methyl carbamate (NMC) insecticides, such as aldicarb, carbofuran, methomyl, oxamyl, and thiofanox as having an influence on the human neurological system as they lower enzyme activity. The principal toxicological consequence of the regulatory concern of the EPA in analyzing the NMC’s food, and drinking water,...
