Textile Testing Laboratories in Turkey

A textile testing laboratory measures specific properties of fabric, yarn, trims or finished garments using standard methods and reports the result. Accepting or rejecting the lot is your decision or your buyer's, and a test report is not a certificate on its own.

Which tests do laboratories run, and what belongs elsewhere?

This page lists laboratories that test color fastness, dimensional change in washing (shrinkage), tensile and tear strength, pilling, fabric weight (GSM), pH, and residues such as formaldehyde and aromatic amines from restricted azo dyes. Not every laboratory runs every test; chemical analysis and mechanical testing need different equipment. Lot inspection is the work of quality control companies, and certificate preparation of consulting and certification firms. For other production services, see contract workshops and services.

Ask the laboratory about accreditation scope, standard and samples

• Accreditation: Is it accredited to ISO/IEC 17025? The real question is whether the method you need is inside the accreditation scope. Some systems require this: GOTS 8.0 asks for residue tests to be run in ISO/IEC 17025-accredited (or GLP-qualified) laboratories, using methods within the accredited scope.
• Standard: Does your buyer expect an ISO, TS EN ISO or AATCC (US) method? TS EN ISO is how Turkish documents cite the Turkish edition of an EN ISO standard. Have the standard written with its year.
• Sample: How many pieces are needed, in what size and with what treatment?
• Report: Is it available in English, and does it carry signature and date? What is the lead time, and is an expedited service offered?
• Interpretation: Does the report give only measurements, or also a statement of conformity against your specification?

Where are accredited laboratories registered?

Of the 69 active accredited testing laboratories that the accredited body search of TÜRKAK, Turkey's national accreditation body, returns for the keyword “tekstil” (textile), 34 have an Istanbul address (TÜRKAK, October 2026). The search does not look at names only: the list also includes laboratories of organizations whose main business is not textiles (such as automotive, medical device and plastics manufacturers), so 69 is not a count of textile laboratories. The province is the organization's registered address; the site that runs your test may be in another province. Check on the organization's accreditation certificate that your method is within scope.

Test fees depend on the number of tests, samples and urgent requests

Price depends on the type and number of tests, samples, colors and styles, preparation such as wash cycles, whether the test is within the accredited scope, report language and urgent requests. Chemical and mechanical testing may be priced separately. Ask for a quote per test and per sample; if a package price is offered, have its tests listed one by one.

Test before cutting, on the approved sample

Do not leave testing until shipment. If you test before the fabric goes to cutting, and on the approved sample, you can still fix a bad result. A laboratory test does not replace AQL inspection: the sampling in our AQL inspection guide counts visible defects, while shrinkage, fastness and chemical compliance are measured in a laboratory. For the difference between documents and claims, see the textile certifications guide. Ask whether the laboratory accepts samples by courier; for many samples or urgent jobs, a laboratory you can reach by hand saves time, and the province filter helps you find one near the factory.
