The ASTM D5660 test method is the legacy standard test method for assessing the microbial detoxification of chemically contaminated water and soil using a toxicity test with a luminescent marine bacterium, Photobacterium phosphoreum. Testing provides valuable information on how a chemical may contaminate water or soil while in use and after disposal.  Sensitive environments can be greatly affected by even […]

ASTM D5660 – Phototoxicity Testing

ASTM D93 determines the flash point of a test substance by a Pensky-Martens closed-cup apparatus. Flashpoint is the lowest temperature at which an ignition source causes the vapors of the test sample to ignite under specified conditions of the test.  The flash point temperature then determines the tendency of the test specimen to form a flammable mixture with air when under these […]

ASTM D93 – Flash Point Test

The ATSM E1052 test is performed to assess the efficacy of antimicrobials against suspended viruses. This is performed by utilizing eukaryotic cell cultures as host systems. This suspension test is meant for special virucidal applications. This includes inactivation of viruses in contaminated liquid wastes as well as determination of virucidal activity for liquid chemicals or […]

The ASTM E2362 method is a standard antimicrobial test for evaluation of pre-saturated or impregnated towelettes utilized for hard surface disinfection. This ASTM method allows to determine if pre-saturated or impregnated towelettes used as hard surface disinfectants exhibit antimicrobial activity. Disinfectant testing is performed under laboratory conditions. Nonporous carriers are inoculated with the selected microorganism […]

Designed for products which form a homogeneous and stable solution when diluted with hard water, or water for RTU products, the EN 1276 suspension test aims to determine the bactericidal activity demonstrated by chemical disinfectants or antiseptics which are intended for food, industrial, domestic and institutional applications. In order to model the actual application of […]

EN 1276: Chemical disinfectants and antiseptics – Quantitative suspension test for the evaluation of bactericidal activity of chemical disinfectants and antiseptics used in food, industrial, domestic and institutional areas

The purpose of the EN 13697 method is to establish the bactericidal, fungicidal or even yeasticidal activity exhibited by chemical disinfectants or antiseptics intended for food, industrial, domestic and institutional applications. This antimicrobial test is designed for products that form a homogeneous and stable solution (when diluted with hard water or with water for RTU […]

EN 13697: Chemical disinfectants and antiseptics – Quantitative non-porous surface test for the evaluation of bactericidal and/or fungicidal activity of chemical disinfectants used in food, industrial, domestic and institutional areas

The EN 1650 test method applies to products intended for food, industrial, domestic and institutional applications. The purpose of this quantitative method is to determine the effectiveness of chemical disinfectants and antiseptics as fungicides or yeasticides (mold and yeast fungi). The test is designated for products that form a physically stable and homogenous solution when […]

EN 1650: Chemical disinfectants and antiseptics – Quantitative suspension test for the evaluation of fungicidal or yeasticidal activity of chemical disinfectants and antiseptics used in food, industrial, domestic and institutional areas

This EPA OPPTS 850.1035 method is an acute toxicity test designed to evaluate the impact of chemical substances and mixtures present in the aquatic environment.  The purpose of this method is to determine the acute toxicity of a material on saltwater mysids in a static, static-renewal, or flow-through system, which allows to assess the hazards […]
