New Standards

Of the four new standards that were developed, two were test methods and two were laboratory procedures.

AATCC TM214-2022, Test Method for Measuring Condensation on Textiles in a Humid Microclimate: New – Developed in 2022 by AATCC Committee RA63.

This newly developed test method is designed 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.  During the test, the outermost fabric (face) surface is subjected to dry and wet conditions (simulated precipitation). The condensation accumulation is determined by calculating the mass change of a filter paper attached to the inner chamber for a prescribed time. The method is applicable to fabrics or multi-layer fabric systems. Read more about TM 214 at www.aatcc.org/tm214/.

AATCC TM215-2023, Test Method for Soil Release: Household Soils: New – Developed in 2023 by AATCC Committee RA56.

This new test method provides a procedure to measure a fabric’s ability to release household soil after laundering. The outcome of the test method is the mean staining grade for each type of common household soil applied to the fabric, such as coffee, ketchup, salad dressing and more. AATCC TM215 serves as a standardized means to quantify fabric or finish performance when exposed to everyday staining scenarios that consumers typically encounter while using fabrics.

AATCC LP4-2023, Laboratory Procedure for Synthetic Soil:  New – Developed in 2023 by AATCC Committee RA57.

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.

AATCC LP5-2023, Laboratory Procedure for Home Laundering with Bleach: New – Developed in 2023 by AATCC Committee RA88.

This new laboratory procedure provides a process for home laundering chlorine and non-chlorine bleach and allows textiles to be tested for compatibility with either type of bleach. Additionally, it provides a means confirm bleach care instructions and can be used in conjunction with various color change evaluations or dimensional stability testing.

Scope Change

AATCC’s RA31 Antimicrobial Activity committee has expanded its scope to include odor testing capabilities. This scope update enables the development of new odor-specific antimicrobial test methods, alongside traditional antimicrobial standards. Expanding committee RA31’s focus on odor will support the textile industry’s growing demand for standardized methods to measure treatments that control both microbial growth and fabric odor.
