The listed materials (apparatus) for testing the wipes are easily accessible in a regular microbiology lab and it requires easy operation procedures to evaluate the disinfecting-wipe ability using glass Petri
Nov 01, 2007 · Background. The RD 50 (exposure concentration producing a 50% respiratory rate decrease) test evaluates airborne chemicals for sensory irritation and has become an American Society for Testing and Materials (ASTM) standard method. Past studies reported good correlations (R 2) between RD 50 s and the occupational exposure limits, particularly threshold limit values (TLVs). ISO - ISO 14851:2019 - Determination of the ultimate Materials which, under the test conditions, do not inhibit the microorganisms present in the inoculum. Inhibitory effects can be determined using an inhibition control or by another appropriate method (see, for example, ISO 8192 ). If the test material is inhibitory to the inoculum, a lower test concentration, another inoculum or a pre ISO - ISO 6341:2012 - Water quality Determination of the ISO 6341.2012 specifies a method for the determination of the acute toxicity to Daphnia magna Straus (Cladocera, Crustacea).. This method is applicable to:chemical substances which are soluble under the conditions of the test, or can be maintained as a stable suspension or dispersion under the conditions of the test; industrial or sewage effluents; treated or untreated waste water; aqueous
Mar 01, 2017 · For standards to guide testing under dynamic conditions, see ASTM E2149 , keeping in mind that this method is designed to determine planktonic rather than biofilm log reductions. While continuous culture systems enable better control of growth rate and other variables such as the complexity and structure of the adhered biomass, batch culture ASTM D5120-90(2009) - Standard Test Method for Inhibition ASTM D5120-90(2009) Standard Test Method for Inhibition of Respiration in Microbial Cultures in the Activated Sludge Process. 1.1 This test method covers a batch procedure that evaluates the impact of selected wastewaters, materials, or specific compounds on the respiration rate of an aqueous microbial culture, such as activated sludge.
