Introduction
Daily washing of textile end products generates fibre fragments which are discharged from washing
machine. The purpose of this test method is to collect materials including fibre fragments which are
discharged from the domestic washing machine through the washing process.
Although there are many types of washing machines used at home, ISO 6330 has been developed for
the domestic washing test method, which specifies the domestic washing machines and test conditions.
This document utilizes one of the standard washing machines in ISO 6330.
In addition, a care label is attached to textile end products in many countries of the world and this care
label specifies washing conditions to use in this document.
Due to the complicated internal structure of washing machines, the cleaning process of the machine
is very important to avoid contamination. This document proposes the checking method and the
requirements of the washing machine to be used in this document.
The identification and quantification of components contained in the collected materials through the
washing process are determined by applying ISO 4484-2.
The information gathered from this document can be utilized by the textile industry for the development
of textile end products to reduce or minimize shedding materials from textile end products through the
washing process.

4 Principle
A given mass of textile end products is washed in a domestic washing machine under certain
temperature and mechanical conditions for a given number of washing cycles. The material shed
through the washing cycles is collected in a filter bag which is attached at the outlet hose of the
washing machine. The collected materials in filter bag are transferred to the membrane filter and the
membrane filter with the collected materials are weighed in the weighing bottle. The membrane filter
and weighing bottle are prepared in combination. The mass of the collected materials is calculated by
the subtracting the original mass of the membrane filter and weighing bottle from the mass with the
collected materials. The mass of collected materials, the ratio of the mass of the collected materials
and the test specimen mass and the mass of the collected material per piece of textile end product are
reported.

7 Test condition
7.1 Standard atmosphere for preparation of test specimens and mass measurement
The standard atmosphere for test specimen preparation and mass measurement are at the temperature
of (20 ± 2) °C and the relative humidity of (65 ± 4) % in accordance with ISO 139.
7.2 Test atmosphere for washing test
The condition for the washing test is ambient condition.
8 Test specimen preparation
Only one kind of textile end products is applied in this washing test. Different kinds of textile end
products shall not be mixed in the washing test. The number of the test specimens per washing test (S )
n
is at least two textile end products. The maximum dry volume of all test specimens per washing test
shall be not more than half of the volume of the washing tub.
The washing test is repeated for three (3) sets.
The number of the test specimens can affect the test result, which is shown in Annex G as an example.
The test specimens are conditioned in accordance with ISO 139. The total mass of the conditioned test
specimens (M ), which is measured using a balance (5.4), shall be up to 1 g and reported in the test
p
report.
9 Test procedure
9.1 General
The washing machine used in this test shall meet the requirement described in Annex B. Once met the
requirement, the washing machine can be used continuously for the washing test.
For the consecutive washing test, take a procedure from 9.2.
The washing conditions of this test procedure is indicated by the care label attached to the textile end
products in accordance with ISO 3758. The details of the washing condition are referred to ISO 6330.
If the countries use their own care label system or care instruction system, set the washing condition
indicated by their system or if there is no label, run the washing program agreed among the interested
parties.
9.2 Empty washing cycle before the washing test
Mount the filter bag (5.2) to the outlet hose of the domestic washing machine (5.1) and tie up by cable
tie (5.6). Run one washing cycle of the washing program without test specimens. The washing program
is the same as the washing test in 9.3. After completion of the washing cycle, remove the filter bag
from outlet hose. Measure the mass of the collected materials by following the steps from 9.4 to 9.5
and Clause 10 and report the mass of the collected materials from the empty washing cycle in the test
report. This is an information of the test washing machine condition.
ISO 4484-3:2023(E)
9.3 Washing test of the test specimen
Mount the filter bag (5.2) to the outlet hose of the domestic washing machine (5.1) and tie up by cable
tie (5.6). Put the test specimens into the washing tub and run one test washing cycle of the washing
program.
The detergent may be used for washing test and the preferable detergent is introduced in Annex D.
When the multiple numbers of the test washing cycle are required, run the number of the washing
cycles as determined by the interested parties according to Annex E. An example of the results of the
multiple numbers of test washing cycles is shown in Annex E.
After completion of the washing cycle, remove the test specimens from the washing tub.
Then, run 2 empty washing cycles by the same washing program.
The number of empty washing cycles (2 empty washing cycles) after test washing was determined by
the results as shown in Annex C.
After completion of the empty washing cycle, remove the filter bag from outlet hose.
nd rd
For the 2 and 3 sets of the test specimens, run the washing test in 9.3.
9.4 Washing of the collected material from the filter bag
Prepare four (4) glass beakers (5.12) containing 1 l of water (6.1) separately. Wash the filter bags of 9.2
and 9.3 in the glass beakers by turning the filter bags inside out and carefully checking that there are
no fibre remnants. The solution in the beaker is the suspension solution of the collected materials.
Place the test specimen with outside side out, and with the zip up or button on if applicable, into the
washing tub.
9.5 Measurement of the mass of the collected materials
Prepare four (4) polycarbonate membrane filters (5.7) and four (4) weighing bottles (5.8) in
combination and separately, it is essential to keep each membrane filter/weighing bottle combination
consistent throughout the duration of the test. Measure the mass of the original membrane filter (5.7)
and a weighing bottle (5.8), respectively, and record them up to 0,1 mg and denoted as (M ).
f1
Membrane filters (5.7) are handled by tweezers (5.11). The membrane filter (5.7) shall be kept in the
weighing bottle (5.8) to prevent contamination from the environment.
Set the membrane filter (5.7) on a vacuum filtration device (5.9).
Filter the suspension solution of 9.4 by the membrane filters on a vacuum filtration device (5.9). Add 1 l
of water (6.1) to the beaker and wash the filter bag again and filter the suspension solution by the same
membrane filter. Repeat this procedure at least twice. Finally, wash the surface of the filter bag and
the inside of the beaker by water (6.1) using a wash bottle (5.10), and this suspension solution is also
filtered by the same membrane filter.
Place the membrane filter with collected materials into the original weighing bottle of 9.5 in combination
and dry for 2 h at (105 ± 3) °C in the oven (5.5). Then place the weighing bottle with the membrane filter
and collected materials in desiccator (5.13) to cool down to the room temperature.
Condition the membrane filter with the collected materials and the weighing bottle under standard
atmospheres in 7.1.
Measure the mass of the conditioned membrane filter with the collected material and the weighing
bottle up to 0,1 mg by the analytical balance (5.3) and record the result as (M ).
f2
ISO 4484-3:2023(E)
At this time, measure of the mass several times at intervals of 1 h or more. The mass is determined
as the weighed value that shows a difference compared to the former and subsequent measurements
