NOTES
1. Test method–5 < DC indicates that the product must not shrink more than 5%.
Three dry clean cycles according to ISO 3175 Normal or equivalent for the commercial dry-clean
test (CDT). Actual product dimensions must be measured and must be equal to (or greater than)
the stated dimension on the label.
2. Sample for testing
Sample products must be submitted to The Woolmark Company for consideration. It is
recommended that the sample size is a single bed size product (or its equivalent). However,samples of 1.0×1.0m will be accepted.
3. Appearance after cleaning or washing
In assessing the acceptability of a product for a dry clean only, hand wash or machine wash careclaim, the surface appearance before and after the specified washing cycles will be considered.
‘Acceptable’ after dry clean appearance is assessed on the level or degree of:• felting and consolidation• binding, product or pattern distortion.

Tumble dry
Any product to be labelled ‘Tumble dry’ must be sent to the local office of The Woolmark
Company, which will submit the product to the designated Woolmark laboratory for testing andassessment of compliance to the appropriate specification.
3. Woolmark TM193: Colourfastness to machine washingThis test applies to coloured products only.
Testing carried out according to Part A using standard detergent without perborate and Part B
with perborate. If the product fails Part B only, additional labelling requirements must be strictly
observed to prevent problems that could arise when a detergent containing bleach is usedduring machine washing of the bedding product. In this case, all tickets/labels attached toproducts must carry an advisory statement: ‘Wash using a Woolmark approved detergent’ (orsimilar). Full details of these additional requirements are available from The Woolmark
Company.
4. Woolmark TM174: Colourfastness to wet alkaline contact

ADDITIONAL CLAIM: Pure Merino Wool
PRODUCTS
Pure Merino Wool may be applied to all Woolmark labelled bedding products meeting the criteria
detailed in this specification.
Pure Merino Wool must not be used on Woolmark Blend or Wool Blend labelled products.

1. The mean fibre diameter is determined from the yarn (or fibre if appropriate) removed from thefully finished product.
The fibre diameter requirement (which includes sampling and testing tolerances) is applicable atthe end product stage. The mean fibre diameter can increase during textile processing as a resultof preferential loss of finer fibres. It is not known how much change will occur for any particular
set of circumstances but in order to meet the end product requirement, it is advised that wools
with diameters closer to 21.5–22.0µm be chosen at the raw material stage.
A composite specimen including all yarn types must be evaluated in the proportions in which they
appear in the fabric.
2. In cases of dispute, the result from Woolmark TM24 must be accepted.

NOTES
1. Woolmark TM31 Dimensional Stability–5 < DC indicates that the maximum shrinkage allowable is 5%.
Acceptable indicates a minimal level of after wash felting and consolidation.
2. CWT test method
A machine with a gentle action wool cycle must be used.
A Woolmark labelled detergent at the recommended dose is preferred.
The following cycle parameters are used for the CWT cycle:
Warm wash
