Introduction
This document describes a test method for determining the disintegration rate of plastic materials exposed to a composting environment. The method is simple, low cost,
Experiments can be performed in any general-purpose laboratory without the need for special biological containers. It requires the use of standard and homogeneous man-made solid waste. people
Solid waste components are required to be dry, clean, safe, and can be stored in the laboratory without odor or health hazards. man-made solid waste
The score does not contain any other plastic materials, because at the end of the test, other plastic materials will be considered as test materials, thus affecting the final evaluation.
The biological container has a small capacity, and there is very little man-made solid waste (about 3L) that needs to be composted. Due to the limited number of test materials, this method simplifies
test steps. The purpose of the test method is not to determine the biodegradability of plastic materials under composting conditions, such as those declared compostable,
Further testing is required.
Plastics under simulated composting conditions at laboratory scale
Determination of the disintegration rate of plastic materials
1 Scope
This document describes a method for determining the disintegration rate of plastic materials under simulated composting conditions at the laboratory scale.
This document does not apply to the determination of the biodegradability of plastic materials under composting conditions. If declared to be compostable, further testing is required.

3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
compost
Organic soil conditioner obtained from the biological decomposition of the mixture. The mixture consists mainly of plant residues and sometimes some organic matter
and certain inorganic substances.
3.2
compostability
The ability of materials to be biodegraded during the composting process.
NOTE. If compostability is claimed, it needs to be stated that the material is biodegradable and disintegrates in the composting system (as shown in the standard test method), and that it is
It is fully biodegradable in use. Composting needs to meet relevant quality standards, such as low heavy metal content, no biological toxicity, no clearly distinguishable
the remains.
3.3
composting
An aerobic treatment method that produces compost.
3.4
disintegration disintegration
The material physically breaks down into extremely fine fragments.
3.5
dry mass drymass
The measured mass of the sample after drying.
NOTE. The dry mass is expressed as a percentage of the wet weight of the sample.
