Summary
ISO 14852 is a test that determines the ultimate biodegradability of plastic materials in an aerobic, aqueous medium. This test measures the CO2 evolution during biodegradation in continuously aerated bottles. This test can last up to six months based on the needs of your products.
ISO 14852 Testing Method
ISO 14852 determines the biodegradability of a plastic material by measuring the CO2 evolution during the biodegradation process over six months. As biodegradation takes place, CO2 and H2O are formed, and the CO2 production is measured at the end of the test. The measured CO2 is compared to the theoretical CO2 to easily calculate the degradation percentages over the six months.
This test is appropriate for highly soluble, poorly soluble, insoluble, and/or absorbing materials. Natural and/or synthetic polymers, copolymers, and mixtures can be tested using this method, along with plastic materials that contain additives such as plasticizers, colorants, and other compounds.

ISO 14852 Requirement and Applicability
Different testing methods are applicable for materials with different properties. Below is a summary of the applicability of ISO 14852. Please check our Method Selection Guide to select the most appropriate method for your materials. You can also find the applicability for many other methods in our Resource Center.| Test | Analytical method | Sample info required * | Poorly soluble | Volatile | Adsorbing |
|---|---|---|---|---|---|
| ISO 14852 | CO2 evolution | Organic carbon content * | + | - | + |
*“Sample info required” is the information needed to calculate the biodegradation percentages. This must be available for a selected method.
*“Organic carbon content” is the ratio of the organic carbon weight to the weight of the sample. It can be calculated by the sample formula (e.g., acetic acid C2H4O2, carbon content is 12*2/(12*2+1*4+16*2)=40%). Try our Online C% Calculator. If the formula is unknown, we can send the sample out to a third party lab for you for analysis (normally $110 with a 10-day turnaround time).
