AATCC Manual of International Test Methods and Procedures/2023 AATCC TM109-2011(2016)e 191

Developed in 1963 by AATCC Commit-

tee RA33; revised 1972, 1986, 1987,

2011; reaffirmed 1971, 1975, 1983,

1992, 2002, 2005, 2016; editorially

revised 1981, 1982, 1983, 1985, 1989,

1995, 2008, 2010, 2019; editorially re-

vised and reaffirmed 1997. Partly

equivalent to ISO 105-G03.

1. Purpose and Scope

1.1 This test method is intended for de-

termining the resistance of the color of

textiles to the action of ozone in the at-

mosphere at room temperatures with rela-

tive humidities not exceeding 67%.

2. Principle

2.1 A test specimen is exposed to

ozone in an atmosphere under ambient

temperatures (64-82°F) and relative hu-

midities not exceeding 67%. The cycle is

repeated (1) until the specimen shows a

definite color change or (2) for a pre-

scribed number of cycles.

3. Terminology

3.1 colorfastness, n.—the resistance of

a material to change in any of its color

characteristics, to transfer of its color-

ant(s) to adjacent materials or both, as a

result of the exposure of the material to

any environment that might be encoun-

tered during the processing, testing, stor-

age or use of the material.

4. Safety Precautions

NOTE: These safety precautions are

for information purposes only. The safety

precautions are ancillary to the testing

procedures and are not intended to be all

inclusive. It is the user’s responsibility to

use safe and proper techniques in han-

dling materials in this test method. Manu-

facturers MUST be consulted for specific

details such as material safety data sheets

and other manufacturer’s recommenda-

tions. All OSHA standards and rules

must also be consulted and followed.

4.1 Good laboratory practices should

be followed. Wear safety glasses in all

laboratory areas.

4.2 Manufacturer’s safety recommen-

dations should be followed when operat-

ing laboratory testing equipment. To pro-

tect the eyes further, do not look at ozone

generator while it is operating.

4.3 Ozone is a sensory irritant. The test

cabinet should be vented to the outside

atmosphere in accordance with the manu-

facturer’s specifications. Ozone in even

moderate concentrations is injurious to

health.

4.4 Exposure to chemicals used in this

procedure must be controlled at or below

levels set by governmental authorities

(e.g., Occupational Safety and Health

Administration’s [OSHA] permissible ex-

posure limits [PEL] as found in 29 CFR

1910.1000; see web site: www.osha.gov

for latest version). In addition, the Ameri-

can Conference of Governmental Indus-

trial Hygienists (ACGIH) Threshold

Limit Values (TLVs) comprised of time

weighted averages (TLV-TWA), short

term exposure limits (TLV-STEL) and

ceiling limits (TLV-C) are recommended

as a general guide for air contaminant ex-

posure which should be met (see 12.1).

5. Uses and Limitations

5.1 Although this test works well for

some substrates, it is not suitable for ny-

lon carpets. For nylon carpets, refer to

AATCC TM129, Test Method for Color-

fastness to Ozone in the Atmosphere Un-

der High Humidities.

6. Apparatus and Materials (see 12.2)

6.1 Ozone exposure chamber for ambi-

ent temperatures and relative humidities

not to exceed 67% (see 12.3).

6.2 Gray Scale for Color Change

(AATCC EP1) (see 12.4).

7. Test Specimens

7.1 Cut each test specimen at least 10.0

× 6.0 cm (4.0 × 2.375 in.). For subse-

quent color comparisons, keep the unex-

posed sample in an airtight container

away from light to avoid shade change.

7.2 When a laundered or drycleaned

specimen is used, the effects of ozone are

based on comparisons with the color of

the unexposed laundered or drycleaned

specimen. To prepare specimens for

testing after laundering or drycleaning,

use AATCC TM61, Test Method for Col-

orfastness to Laundering: Accelerated, and

AATCC TM132, Test Method for Color-

fastness to Drycleaning, respectively.

8. Procedure

8.1 Suspend the test specimens in the

exposure chamber (see 12.3). The test ap-

paratus should be located in a room in

which the ambient air temperature is 18-

28°C (64-82°F) and the relative humidity

does not exceed 67%. For reference and

interlab testing, conduct tests in a room

or chamber with the standard atmo-

spheric conditions of 21 ± 2°C (70 ± 4°F)

and 65 ± 5% RH. Ozone should be

present in concentrations of 4.5 ± 1 ppm

for 4.5 ± 1 h. This constitutes one cycle

(see 12.5).

8.2 Remove those specimens which

exhibit a color change at the end of one

cycle. One cycle will generally produce a

measurable color change in specimens

which are ozone sensitive.

8.3 Run additional similar cycles as

necessary.

9. Evaluation

9.1 At the end of each cycle immedi-

ately compare those specimens which are

removed from the exposure chamber with

the preserved originals from which they

were drawn.

9.2 Rate the effect on color of test

specimens after any specified number of

cycles by reference to the Gray Scale for

Color Change (AATCC (EP1) or using

AATCC EP7, Instrumental Assessment

of the Change in Color of a Test Speci-

men, and record the numerical rating that

corresponds to the appropriate one on the

Gray Scale. Report the number of cycles

run (see 12.6).

10. Report

10.1 Report the numerical grade for the

change in color of each test specimen, the

number of cycles run and the temperature

and relative humidity at which the test

was performed.

11. Precision and Bias

11.1 Precision. Precision for this test

method has not been established. Until a

precision statement is generated for this

test method, use standard statistical tech-

niques in making any comparisons of test

results for either within-laboratory or

between-laboratory averages.

11.2 Bias. Colorfastness to ozone in

the atmosphere under low humidities can

be defined only in terms of a test method.

There is no independent method for de-

termining the true values. As a means of

estimating these properties, the method

has no known bias.
