Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
The test method described in this International Standard determines the degree of disintegration of plastic
materials when exposed to a composting environment. The method is simple and inexpensive, does not
require special bioreactors and is scaled for use in any general-purpose laboratory. It requires the use of a
standard and homogeneous synthetic solid waste. The synthetic waste components are dry, clean, safe
products which can be stored in the laboratory without any odour or health problems. The synthetic waste is of
constant composition and devoid of any undesired plastic material which could be erroneously identified as
test material at the end of testing, altering the final evaluation. The bioreactors are small, as is the amount of
synthetic waste to be composted (approximately 3 l). With the limited amount of test material, this method
provides a simplified test procedure. This test method is not aimed at determining the biodegradability of
plastic materials under composting conditions. Further testing will be necessary before being able to claim
compostability.

INTERNATIONAL STANDARD ISO 20200:2004(E)

Plastics — Determination of the degree of disintegration of
plastic materials under simulated composting conditions in a
laboratory-scale test
1 Scope
This International Standard specifies a method of determining the degree of disintegration of plastic materials
when exposed to a laboratory-scale composting environment. The method is not applicable to the
determination of the biodegradability of plastic materials under composting conditions. Further testing is
necessary to be able to claim compostability.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
compost
organic soil conditioner obtained by biodegradation of a mixture consisting principally of vegetable residues,
occasionally with other organic material and having a limited mineral content
3.2
compostability
ability of a material to be biodegraded in a composting process
NOTE To claim compostability it must have been demonstrated that a material can be biodegraded and disintegrated
in a composting system (as can be shown by standard test methods) and completes its biodegradation during the end-use
of the compost. The compost must meet the relevant quality criteria. Quality criteria are e.g. low heavy-metal content, no
ecotoxicity, no obviously distinguishable residues.
3.3
composting
aerobic process designed to produce compost
3.4
disintegration
physical breakdown of a material into very small fragments

3.5
dry mass
mass of a sample measured after drying
NOTE Dry mass is expressed as a percentage of the mass of the wet sample.
3.6
mesophilic incubation period
incubation at 25 °C to allow the development of microorganisms growing at room temperature
3.7
thermophilic incubation period
incubation at 58 °C to allow the development of microorganisms growing at high temperature
3.8
total dry solids
amount of solids obtained by taking a known volume of test material or compost and drying at about 105 °C to
constant mass
3.9
volatile solids
amount of solids obtained by subtracting the residue obtained from a known volume of test material or
compost after incineration at about 550 °C from the total dry solids content of the same sample
NOTE The volatile-solids content is an indication of the amount of organic matter present.
4 Principle
The method determines the degree of disintegration of test materials on a laboratory scale under conditions
simulating an intensive aerobic composting process. The solid matrix used consists of a synthetic solid waste
inoculated with mature compost taken from a commercial composting plant. Pieces of the plastic test material
are composted with this prepared solid matrix. The degree of disintegration is determined after a composting
cycle, by sieving the final matrix through a 2 mm sieve in order to recover the non-disintegrated residues. The
reduction in mass of the test sample is considered as disintegrated material and used to calculate the degree
of disintegration.
5 Synthetic solid waste
The composition of the synthetic waste used in this method is described in Table 1.
Well aerated compost from a commercial aerobic composting plant shall be used as the inoculum. The
compost inoculum shall be homogeneous and free from large inert objects such as glass, stones or pieces of
metal. Remove any such objects manually and then sieve the compost on a screen of mesh aperture between
0,5 cm and 1 cm. It is recommended that compost from a plant composting the organic fraction of solid
municipal waste be used in order to ensure sufficient diversity of microorganisms. If such a compost is not
available, then compost from plants treating farmyard waste or mixtures of garden waste and solid municipal
waste may be used. The compost shall not be older than 4 months.
Prepare the synthetic waste manually by mixing the different components listed in Table 1. The allowed
tolerance on the mass measurements of the synt
