Wool Testing Authority Europe Caernarfon Laboratory
Wool Testing Authority (Europe)Caernarfon, Gwynedd
UKAS schedule 2680 identifies Wool Testing Authority Europe at Unit 7 Lon Barcud, Caernarfon, with testing only at that address. Its wool methods cover diameter, base/vegetable matter, colour and mass. The operator distinguishes controlled-sampling IWTO certificates from reports on customer-submitted samples; the licensing list is a separate method authority.

Key facts
Public information not available. Contact test facility provider for more information.
Testing capabilities
Wool fibre diameter
The schedule lists airflow mean-diameter methods for combed sliver and raw-wool core samples, plus mean and distribution measurement using the Sirolan-Laserscan analyser. These are distinct listed methods rather than interchangeable certificate routes.
Wool base, vegetable matter and colour
Site-only scope includes wool-base and vegetable-matter determination from raw-wool core samples, including Appendix K by NIRA but excluding Appendix L, and raw-wool colour measurement. Dichloromethane-soluble matter testing separately excludes NIR testing.
Mass and certificate calculations
The schedule lists oven-dry and calculated invoice mass for scoured/carbonised wool and wool tops, merchantable mass for tops, and calculation of combined certificates for raw-wool deliveries.
Equipment and published limits
| Specification | Published value | Conditions |
|---|---|---|
| Operator-described conditioning | 20°C and 65% relative humidity; approximately 18 hours | The operator describes this conditioning process for micron and colour testing. Confirm the actual specimen-conditioning and method requirements; this is not a total turnaround or shipment acceptance promise. |
Access and contact
The Caernarfon contact page publishes testing@wtaeurope.com for technical work, sampling@wtaeurope.com for sampling, and +44 (0)1286 678097 for Wales. Customer-submitted samples receive reports where certificate sampling is not possible; for an IWTO certificate the local sampling agent packages and sends the sample.

Standards and accreditation
- ISO/IEC 17025:2017 — UKAS 2680
- The retained issue 018 schedule dated 13 June 2025 is address-only and lists individual IWTO methods/editions and exclusions. The IWTO licensing page separately lists licence 17 for methods 6, 10, 19, 28, 31, 33, 34 and 56; its retained list does not include method 12 even though the UKAS schedule does.
What to confirm with the facility
- An IWTO certificate requires the operator’s controlled sampling, testing and documentation process. Customer-submitted samples can receive a report without guaranteeing sampling integrity. UKAS method scope and IWTO certificate licensing are separate requirements.
- Confirm the fibre/product, exact method and edition, certificate versus report route, sampling and shipping arrangements, required accreditation, availability and quotation directly with the laboratory.

WTA Europe wool-testing services and certificate/report distinction
Operator services page describes physical testing methods, conditioning and the distinction between IWTO certificates and customer-submitted reports. Methods are assigned to the exact laboratory only where the site-only schedule supports them.
IWTO licensed laboratories — WTA Europe Caernarfon entry
Exact Caernarfon entry identifies UKAS 2680 and IWTO licence 17 for its named method list. The retained IWTO list is distinct from UKAS schedule scope, particularly for IWTO 12.
Operator shipping page distinguishes agent-controlled certificate sampling from customer shipping. General import-law wording is not turned into universal shipment advice in this guide.
WTA Europe contact and UK office
Exact contact page identifies Unit 7 Lon Barcud and distinct technical, sampling and general routes; a UKAS exact-site schedule separately establishes laboratory allocation.
UKAS 2680 WTA Europe, issue 018
Issue 018 dated 13 June 2025 supports Caernarfon address-only wool physical/chemical methods with the stated NIR/Appendix exclusions and individual IWTO editions. It does not establish IWTO certificate licensing for every UKAS-listed method.
