GB/T 40367-2021 (Plastics - Determination of the aerobic biodegradation of nonfloating materials exposed to marine sediment - Method by analysis of evolved carbon dioxide) is available as an English-translated PDF.
GB/T 40367-2021 is the Chinese standard "Plastics - Determination of the aerobic biodegradation of nonfloating materials exposed to marine sediment - Method by analysis of evolved carbon dioxide".
Its scope clause reads: This 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. Its clauses include terms and definitions.

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). […]
