Setting up a textile testing laboratory: an equipment and infrastructure checklist

A new textile laboratory usually starts with a list of instruments. That is the wrong first page. The instruments are the easy part; what delays a laboratory by months is a conditioned room that cannot hold humidity, a washing machine with no drain, a flammability cabinet with no extraction, or a three-phase machine delivered to a single-phase building.

This checklist is written in the order the decisions have to be made.

1. Define the scope from your customers, not from a catalogue

List the specifications your customers actually send — buyer manuals, test packages, regulatory requirements for the markets you ship to. Turn that into a matrix:

The last column matters. A test you run twice a year may be cheaper to send out; a test you run every day justifies a second station. Laboratories that skip this step end up with expensive instruments that are rarely switched on, and queues at the crockmeter.

2. Zone the space before you choose the furniture

Textile testing needs at least four kinds of space, and they do not mix well:

• Conditioned testing room. Physical tests — tensile, tear, abrasion, pilling, thickness, mass per area — are carried out on specimens conditioned in, and usually tested in, the standard atmosphere of ISO 139: 20 ± 2 °C and 65 ± 4 % RH. This room needs a dedicated air-handling unit sized for the room volume, the people in it and the heat from instruments. See our article on ISO 139 conditioning.
• Wet area. Washing machines, tumble dryers, wash-fastness testers, dyeing equipment. Floor drains, hot and cold water, possibly softened water, steam or high electrical loads. Keep it physically separate from the conditioned room; it is a constant source of humidity.
• Colour assessment area. A light cabinet for grey-scale assessment and shade evaluation, away from windows and away from strongly coloured walls. Visual assessment conditions are described in ISO 3664; the point here is that daylight from a window and the colour of the surrounding surfaces both affect what the assessor sees.
• Flammability area. Gas supply, extraction that can be switched off during the burn and run afterwards, non-combustible surfaces, and fire-safety equipment. Never inside the conditioned room.

A small sample preparation zone — cutting tables, die cutters, a balance — sits best between the conditioning room and the reception area.

3. Check the building, instrument by instrument

For every instrument on your list, request the installation data and fill in this table before you sign an order:

Two examples from our own range show why this matters: a three-station Vettermann drum tester needs a 380–415 V three-phase supply, and the six-station version weighs about 1,080 kg. Neither is a surprise you want on delivery day.

4. Buy the foundation instruments first

Some instruments sit underneath almost every test. Buy them first and buy them properly:

• Conditioning — the room unit or a conditioning cabinet, plus an independent temperature and humidity logger to prove the room was in specification.
• Balance — of the right capacity and readability for mass per area, yarn count and specimen weighing.
• Specimen cutting — circular cutters and dies for mass per area and other fixed-area specimens.
• Assessment lighting — a light cabinet with the light sources your customers specify.

Then add the instruments for your highest-volume tests from the matrix, and leave specialised, low-volume equipment until the laboratory has a track record.

5. Plan consumables and reference materials as a supply chain

Many textile tests depend on standardised consumables: multifibre adjacent fabrics, crocking cloths, standard abradant fabrics, reference detergents, grey scales, blue wool references. Results depend on them as much as on the instrument.

• Keep a register with lot number, date received and, where relevant, expiry or replacement interval.
• Hold enough stock for your lead time plus a margin; a test package that stops because one consumable ran out is a delivery failure.
• Grey scales and reference materials age and get handled; plan their replacement.

6. Plan acceptance, not just delivery

When an instrument arrives, the job is not finished until it has been shown to work for the tests it was bought for. For each instrument, agree in advance:

• what the supplier will demonstrate at installation;
• which calibration or verification certificates are delivered;
• what the laboratory will check itself before using the instrument for customer work — for example running a known material and comparing with an expected result.

If you intend to work towards ISO/IEC 17025, this is the same step the standard calls verifying that equipment conforms to specified requirements before it is placed into service. It is cheaper to design it in now than to reconstruct it later.

7. People and records

Assign an owner to every instrument. Write a short working instruction for each test, based on the current edition of the standard, and train at least two people on every test that customers depend on. Start the equipment records on day one: identity, serial number, location, calibration status, maintenance and any repairs.

Common first-year mistakes

1. Light cabinet next to a window.
2. Analytical balance on the same bench as an abrasion tester.
3. Conditioned room sized for the instruments, with no space for conditioning racks.
4. Flammability cabinet installed where extraction cannot be controlled.
5. Consumables bought once, with no reorder point.

We build our instruments in our own workshop in Istanbul and can provide installation data for each of them during the planning stage.
