Water and Environmental Testing

Scope: The standard test method to analyse liquid chlorine for low levels of water ASTM E1754-17a uses infrared spectrophotometry. It can be used for water concentrations ranging from 0.5 to 15 mg/kg (ppm). The values stated are stated in SI units. Test Procedure: In the ASTM E1746-17a test method, a sample of liquid chlorine is...

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...

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...

Scope: ASTM E598-08 test method covers the determination of heat transfer rates of solids. The heat flux is measured, and the changes in the heat transfer rates of solids are determined when placed in different gaseous environments. The results obtained help in the performance evaluation, quality control, and research. The applications can be specified, which...

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...

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,...

Scope: ASTM D7599 test method deals with the determination of ethanolamines in surface water which serve as chemical weapons. There can be varied uses of these chemical weapons, such as their application in the production of adhesives, agricultural products, cement grinding aids, detergents, various chemical products, polishes, pesticides, and pharmaceuticals. These ethanolamines are biodegradable and...
