AATCC: 2023 Midyear New And Revised Standards

RESEARCH TRIANGLE PARK, N.C. — August 28, 2023 — AATCC publishes standards that have been approved since the new year release of the AATCC Manual of International Test Methods and Procedures. The standards are available for download from the AATCC store. Get access to either the full set of midyear standards or individual standards.

This year, twenty-one (21) approved standards have been developed or revised since publication of the 2023 volume of the AATCC Manual of International Test Methods and Procedures. This includes new Lab Procedures, one for using bleach in home laundering and another for preparing synthetic soil as well as one new standard for measuring condensation. Of the 21 approved standards, three were newly developed, nine test methods were revised, and nine other test methods were editorially revised.

2023 New Test Methods and Lab Procedures

The new test method and laboratory procedures are as follows:

AATCC TM214-2022, Test Method for Measuring Condensation on Textiles in a Humid Microclimate: The purpose of this newly developed test method is to measure water condensation accumulation in the innermost (back) surface of fabrics in a humid microclimate, with and without simulated precipitation on the outermost (face) fabric surface. The method is applicable to fabrics or multi-layer fabric systems. Read more about TM 214 at www.aatcc.org/tm214/.

This new test method was developed by RA63 in 2022. RA63 is the Water Resistance, Absorbency & Wetting Agent Evaluation research committee that is responsible for developing test methods for evaluation of water-resistance and repellency of textiles.

AATCC LP04-2023, Laboratory Procedure for Synthetic Soil: Synthetic soil was developed for standardized carpet soiling. It is used as a soiling option for stain and soiling evaluations. Though synthetic soil originated from carpet-related methods, its use is not limited and can be used in other methods requiring a synthetic soil application. Read more about LP4 at www.aatcc.org/improved-soil-standards/.

This new laboratory procedure was developed by RA57 in 2023. RA57 is the Floor Covering Test Methods research committee that is responsible for developing test methods that will reliably predict the use characteristics of all types of floor coverings.

AATCC LP5-2023, Laboratory Procedure for Home Laundering with Bleach: This new procedure provides standard conditions for home laundering with bleach, using an automatic washing machine. Option 1 is for sodium hypochlorite (“chlorine bleach”). Option 2 is for sodium percarbonate (“non-chlorine bleach”). This test is applicable to all fabrics and end products suitable for home laundering. It may be used to determine whether a sample is suitable for laundering.

This new laboratory procedure was developed by RA88 in 2023. RA88 is the Home Laundering Technology research committee which aims to encourage and promote discussions on current developments and problems associated with the use of standard and new chemical materials, including soaps and detergents, bleaches, water and fabric softeners, enzymes, and any other auxiliaries available to the consumer for use in home laundering and coin-operated machines, which may affect color, performance and special functional finishes and the ecology.

2023 Revised Test Methods

The revised test methods are as follows:

2023 Editorially Revised Test Methods and Evaluation Procedures

The editorially revised test methods and evaluation procedures are as follows:

Withdrawn Standards

These standards will no longer be included in the full year publication of the AATCC Manual of International Test Methods and Procedures.
