The ASTM C1338 method is a standard antifungal test for determining fungi resistance of insulation materials and facings. Insulation and facings products may be susceptible to fungal formation under favorable conditions such as high humidity. ASTM C1338 is intended to evaluate the relative ability of such materials to resist fungal growth. Test samples are inoculated […]
OECD 301F is a solutions aerobic biodegradation test that determines the biodegradability of a material by measuring oxygen consumption. OECD 301F is most often used for insoluble and volatile materials that are challenged by OECD 301B testing. The purity or proportions of major components of the test material is important for calculating the Theoretical Oxygen Demand (ThOD). Similarly to other 301 test […]
OECD 301E is a modified aerobic biodegradation test that predominantly measures biodegradation of a material by the evaluation of dissolved organic carbon. OECD 301E is a minimum 28- day test that can be used with samples known to be absorbing materials. OECD 301E is similar to OECD 301 A (DOC Die-Away), but 301E uses a lower concentration […]
OECD 301A is an aerobic biodegradation test used for non-volatile and soluble (100mg/L) substances. In the OECD 301A test method, the degree of biodegradation is measured by the change in Dissolved Organic Carbon (DOC) over a 28-Day period. It is similar to the OECD 301E, but higher microbial cell densities can be used in the OECD 301A. OECD […]
OECD 208 is a terrestrial plant test that determines seedling emergence and growth in composted material resulting from a solid’s biodegradation, like plastic. OECD 208 is used to determine if the composted material is toxic to plants. The OECD 208 test method is used to confirm that biodegraded and composted materials do not introduce toxic components into the […]
ISO 17556 is an ultimate aerobic biodegradation test method that determines the ultimate aerobic biodegradability of a material in soil by measuring oxygen demand in a respirometer or the amount of carbon dioxide evolved. This method is similar to other Compost methods; ISO 17556 is a minimum 90 day aerobic biodegradation test. Instead of measuring Theoretical Carbon […]
ISO 14855 is a standard biodegradation test method that determines ultimate aerobic biodegradability and disintegration of plastic materials under controlled composting conditions. Situ Biosciences has currently suspended testing according to the ISO 14855 due to complications associated with the COVID-19 mandatory quarantine. This method predominantly measures ultimate aerobic biodegradation by the analysis of evolved carbon dioxide. […]
ASTM D5864 is a biodegradation test method for determining aerobic aquatic biodegradation of lubricants or their components. ASTM D5864 determines the degree of aerobic aquatic biodegradation of fully formulated lubricants or their components, based on the exposure to an inoculum under laboratory conditions. Testing is designed to be applicable to all lubricants that are not volatile and are not inhibitory at the test […]
ASTM D5526 is an anaerobic biodegradation test that is used to determine anaerobic biodegradation of plastic materials under accelerated landfill conditions. ASTM D5526 evaluates the percentage of conversion of carbon in the test sample to carbon in the gaseous form (CH4 and CO2) under conditions that resemble landfill conditions. The material that results from testing […]
JIS L 1902 is an antimicrobial product test for testing antibacterial activity and efficacy on textiles. JIS L 1902 is recognized globally for testing antimicrobial additives and was originally developed as a Japanese Industrial Standard for products entering the Japanese market. This method is frequently used for basic fabrics and textiles used in bedding, furniture, and […]
