For many years, laundering conditions and washing machine specifications were included in various AATCC test methods. They were updated by the test method committees as needed.

In 1984, machine parameters were moved to AATCC Monograph 6, Standardization of Home Laundry Test Conditions and maintained by AATCC Research Committee RA88, Home Laundering Technology.

From 1984 to 2017, M6 was gradually expanded to include parameters for a wide range of home washing machines. There was no clear correlation among these machines. As technology changed, it became difficult for labs to obtain washers meeting the published specifications.

In January 2018, several research committees approved revised test methods with aligned, standard laundering conditions. These conditions will be applied to additional methods over the following months and are not expected to change for some time.

  • TM88B-2018, Smoothness of Seams in Fabrics after Repeated Home Laundering
  • TM88C-2018, Retention of Creases in Fabrics after Repeated Home Laundering
  • TM124-2018, Smoothness Appearance of Fabrics after Repeated Home Laundering
  • TM135-2018, Dimensional Changes of Fabrics after Home Laundering
  • TM143-2018, Appearance of Apparel and Other Textile End Products after Home Laundering
  • TM150-2018, Dimensional Changes of Garments after Home Laundering

Also in January 2018, two new Laboratory Procedures were published with standard and alternate laundering conditions. LP1 and LP2 are complete laundering protocols that may be used in coordination with appearance evaluation, flammability preparation, or other procedures. LP1 replaces M6, but provides considerable additional information.

  • LP1-2018, Home Laundering: Machine Washing (supersedes Monograph 6)
  • LP2-2018, Home Laundering: Hand Washing (supersedes Monograph 5)

The 2018 laundering documents listed above are NOT included in the 2018 AATCC Technical Manual. They must be purchased as downloadable PDFs. Choose individual downloads, or save 55% by purchasing all eight in the AATCC 2018 Home Laundering Supplement. This supplement is available ONLY for 2018. All standards included in the supplement will appear in the 2019 AATCC Technical Manual.

Standard Conditions (updated February 12, 2018)
The manufacturers report that these machines meet the parameters listed in the 2018 versions of TM88B, TM88C, TM124, TM135, TM143, and TM150. These parameters are also listed in LP1, Home Laundering: Machine Washing, Table I.

  • SDL Atlas Vortex M6
  • Labtex LBT-M6

Alternate Conditions (updated February 15, 2018)
The manufacturers report that these machines meet the parameters listed in the noted tables of LP1, Home Laundering: Machine Washing.

  • Labtex LBT-M6 (Tables I, IIC, IID, IIIA, IIIB)
  • Labtex LBT-M6T (Tables IIA 1.8-kg load, IIB 1.8-kg load)
  • SDL Atlas Vortex M6 (Tables I, IIC 1.8-kg load, IID 1.8 kg load, IIIA, IIIB)
  • Whirlpool 3LWTW4840YW (Table IIC)
  • Whirlpool 3LWTW4815FW (Table IIIB)
  • Whirlpool 4KWTW4815FW (Table IIIB)
  • Whirlpool WTW5000DW (Table IIIC)

AATCC does not verify the parameters of washing machines or dryers. The list above includes machines reported by the manufacturer to meet the parameters listed in the most recent version of LP1, Home Laundering: Machine Washing and various test methods.

Standard detergent is an important part of correctly and consistently performing textile testing.

Representative Formula
AATCC standard reference detergents are formulated to have the performance of an “average” consumer detergent.  This means the results you see in the lab are likely to match the results an end-product consumer sees at home. No false passes from using a high-end detergent in the lab. AATCC and comparable mid-level consumer detergents are compared for performance in dimensional change,  color change,  color staining, stain release, and general appearance tests.

Consistent Production
The recipes for AATCC detergents are the same lot-to-lot. Using standard detergent throughout your supply chain means one less variable to consider when comparing test data. You can count on closely-monitored consistency—every season, in every location. No need to worry about the impact of new formulas, scents, or additives on your results.

Optical Brightener Options
For colorfastness testing, the optical brighteners present in most detergents can interfere with specimen evaluation. AATCC standard reference detergents without optical brightener (WOB) let you assess color change due to the test procedure, without the added influence of brighteners. This makes it easier to determine whether a particular dye or process is suitable for your product. AATCC detergents are also available with brighteners for general appearance evaluations or other tests where it may be important to replicate the end-product consumer’s laundering experience.
