Not because These products are biodegradable (biodegradable) and are considered to be freely discarded in the environment. This is not desirable. These products should also It is recycling and reuse. However, the test method for determining the degree and rate of biodegradation of plastics in natural environments (such as soil or marine environments) is It is worth paying attention to in order to better describe the degradation behavior of plastics in these specific environments. In fact, some products used in the ocean are made of plastic These products are sometimes lost or intentionally placed in the marine environment. The characteristics of biodegradable plastic materials can be It is characterized by the application of specific test methods, which can be used for the biodegradability of plastics exposed to marine sediments and seawater. Carry out a quantitative assessment. This test method provides a test method for calculating and reporting the level of biodegradation obtained under laboratory conditions using marine inoculants. Law. Marine inoculum is the sediment sampled in the intertidal zone, and the plastic material is exposed to this environmental matrix, and then the released dioxygen is measured Carbonization is performed to determine the degree of biodegradation. Plastic exposure to non-floating materials in marine sediments Determination of final aerobic biodegradability By analyzing the method of released carbon dioxide1 ScopeThis document describes a laboratory method for determining the degree and rate of aerobic biodegradation of plastic materials. This test method is also applicable to its He solid material. The degree of biodegradation is obtained by measuring the carbon dioxide released by plastic materials The sandy intertidal zone was sampled and moisturized with salt water under laboratory conditions. This test method is to simulate the habitat environment of the sandy intertidal zone under laboratory conditions. The sandy intertidal zone is called nearshore shallow in marine science. kelp. The conditions described in this document may not always correspond to the optimal conditions for maximum biodegradation. Deviations from the test conditions described in this document should be stated in the test report.2 Normative referencesThe contents of the following documents constitute the indispensable clauses of this document through normative references in the text. Among them, dated quotations Only the version corresponding to that date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to This document. ISO 10210 Plastics-Methods for the preparation of samples for the biodegradation test of plastic plastic materials samplesforbiodegradationtestingofplasticmaterials)3 Terms and definitionsThe following terms and definitions apply to this document. The terms and definitions used in this document in ISO and IEC can be found on the following website. 3.1 Tidalzone The boundary line between the ocean and the land, from the high tide line which is rarely submerged by water to the low tide line which is often covered by water. Note 1.The intertidal zone is usually a piece of sand, which has been kept moist due to the beating of waves. Note 2.There are also rocky and rocky coastlines. Note 3.The intertidal zone is also called the nearshore shallow sea zone (coastal zone), the coastal zone, the coastal zone, the tidal zone, and the foreshore. 3.2 Theoreticalamountofevolvedcarbondioxide ThCO2 The theoretical maximum value of carbon dioxide that can be generated when the experimental material is completely oxidized can be calculated from the molecular formula or total organic carbon (TOC), as The number of milligrams of carbon dioxide released per milligram or per gram of test material is expressed (mgCO2/g test material or mgCO2/mg test material). ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 40367-2021_English be delivered?Answer: Upon your order, we will start to translate GB/T 40367-2021_English as soon as possible, and keep you informed of the progress.
