WOOLMARK SPECIFICATIONSPECIFICATION CP-4: 2016

PRODUCTS FOR THE INSECT RESIST TREATMENT OF WOOL

For those wool products for which an insect resist treatment is mandatory
This Specification details, for various Insect Resist Agents (IRA), the quantity that must bepresent on a wool product (as active on the weight of wool) for that wool product to bear theWoolmark/Woolmark Blend label. Measurement of the IR agent is done after cleaning andlightfastness testing, as specified in Woolmark TWC-TM28: Insect resist agent – fastness
testing.
For those wool products for which an insect resist treatment is not mandatory
Where the product carries an ‘Insect resistant’ claim, the amount of Insect Resist Agent on thewool must be measured and must also meet the limits detailed in this Specification. For
bedding and apparel, measurement of the concentration of the IR agent shall be made after
the fastness test defined in TWC-TM28 for the appropriate care claim (washable or dry clean
only).
A product shall be accepted as complying with Specification CP-4 if the product fulfils the conditions
described in the Table below.

The methods used to measure the insecticide on the wool are described in Woolmark TWC-TM27:
Chemical assay of insect resist (IR) agent content.
Products treated with a combination of the above IR agents must be referred to the Woolmark
Management Group. New active materials or IR products must undergo biological and fastness testing
and will be reviewed by the Woolmark Management Group before acceptance.

APPLICATIONLEVEL 1

See appropriate product specification sheet for mandatory or advisory status ofrequirement. Signifies resistant to Tineola bisselliella (Hummel).

LEVEL 2Advisory for most products sold in moist, temperate climates. Signifies resistant toTineola bisselliella (Hummel).

LEVEL 3

Mandatory for products sold in South Africa. Advisory for products sold in warmer,drier climates, such as Central and Southern Europe, USA and Japan. Signifies
resistant to Tineola bisselliella (Hummel) and Anthrenus flavipes (Le Conte).

LEVEL 4

Mandatory for products sold in Australia. Signifies resistant to Tineola bisselliella(Hummel), Tinea pellionella (L.), Tinea translucens (Meyrick), Anthrenocerus australis(Hope) and Anthrenus flavipes (Le Conte).

LEVEL 5Mandatory for products sold in New Zealand. Advisory for products sold in a variety ofclimates. Signifies resistant to Tineola bisselliella (Hummel), Tinea pellionella (L.),
Tinea translucens (Meyrick), Anthrenocerus australis (Hope), Anthrenus flavipes (LeConte), Attagenus pellio (L.), Attagenus piceus (Oliv.) and Hofmannophila
pseudospretella (Stainton).

TECHNICAL NOTES
1.

Level 1 is the basic requirement by MANDATORY or ADVISORY status but due consideration
should be given to applying IR agents to higher levels where this is advised for regions withspecific climatic conditions.

2.

In specified countries, the application of IR agent to higher levels is MANDATORY.

3.

For rugs and squares, insect resist treatment is an ADVISORY requirement (LEVEL 1) unlessthere are national MANDATORY requirements. For products sold in Australia (LEVEL 4),
South Africa (LEVEL 3), New Zealand (LEVEL 5) must be applied.

4.

The rates given in the following table are the minimum effective rate; higher levels are
required on products as manufactured.

5.

Products may also be tested by bioassay according to Woolmark TWC-TM25 after fastness
testing according to Woolmark TWC-TM28.

ADVISORY
Levels of insect resist products on the wool after fastness testing that correspond to the specified concentration of active material % w/w.
The following table indicates the minimum concentration of commercial insect resist formulations that must be present on the wool to comply with thisSpecification (CP-4). These are advisory and are based on the information received from the manufacturers about the % active material in the formulation.
The Woolmark Company is not responsible for quality assurance of these formulations or changes in their concentration of active material.

NOTES1

It is the responsibility of the user of any insect-resist agent to ensure that the IRA (and its
active material) is registered for use in the country in which the wool product is sold. TheWoolmark Company is not liable for the use of one or more of the listed products if they are
not registered for use in a particular jurisdiction.

2The Woolmark Company's inclusion of an IR agent in CP-4 in no way implies that industrial
use of these formulations will meet the requirements of various local and national authorities interms of effluent consents, etc. These are local issues that must be resolved from trials carriedout by the manufacturer of the agent and the mills using the product.

3

Application levels of IRAs and the initial concentration required on wool products prior tofastness testing to meet Woolmark limits are determined by the nature of the product and themethod of application. It is the responsibility of the wool processor to ascertain, from thesupplier of the IRA, the application levels required to meet Woolmark requirements. Advisory
information is also available from the regional office of The Woolmark Company.

4The Woolmark Company reserves the right to test listed products by bioassay to confirm theireffectiveness.

5.

The Woolmark Company reserves the right to reject IRAs for ecological or environmental
reasons.
