ISO or AATCC? What You Need to Know When Establishing an Accredited Textile Laboratory.

One of the most frequently asked questions by companies planning to invest in laboratories in the textile industry is this:

"Should we set up our laboratory according to European standards or American standards?"

The answer to this question is not as simple as it seems.

Because today, textile laboratories are no longer just testing units; they have become strategic centers that manage brand approval processes, accelerate product development, reduce customer complaints, and standardize quality.

A poorly planned laboratory can cause significant time and cost losses in a multi-million dollar manufacturing business.

A well-planned laboratory can achieve much higher productivity with the same equipment investment.

First, you should ask yourself this question: Who are you producing for?

The first question to answer before beginning laboratory design is:

"Which brands or markets do we manufacture for?"

should be.

Because the testing expectations of European-based brands are not the same as those of American-based brands.

For example;

• Zara

• Inditex Group

• Mango

• H&M

• Decathlon

• C&A

• Primark

European-based brands, such as these, predominantly require ISO and EN ISO standards.

Against this;

• Walmart

• Target

• PVH

• VF Corporation

• Under Armour

• Columbia

• Hanes

American-based brands like these use AATCC and ASTM methodologies.

In Türkiye, many manufacturers work for both the European and American markets simultaneously.

Especially;

• LC Waikiki

• DeFacto

• Cotton

• Mavi Jeans

• Boyner suppliers

• Exporting knitwear and woven fabric manufacturers

They need laboratory infrastructure that can meet both ISO and customer-specific procedures.

What is the main difference between ISO, AATCC, ASTM, and DIN?

These four names are often confused with each other.

ISO

ISO (International Organization for Standardization) creates internationally accepted standards worldwide.

In the textile industry;

• Washing Fastness

• Friction Fastness

• Sweat Dysfunction

• Lightfastness

• Physical Performance Tests

• Laboratory Environmental Conditions

It encompasses hundreds of standards such as these.

AATCC

The AATCC (American Association of Textile Chemists and Colorists) has been developing testing methodologies for the textile industry since 1921 and is one of the world's leading organizations, particularly in color fastness testing.

Today;

• AATCC 61 (Washing Fastness)

• AATCC 8 (Crocking Fastness)

• AATCC 15 (Perspiration Fastness)

• AATCC 16 (Light Fastness)

Standards like these are used worldwide.

ASTM

ASTM (American Society for Testing and Materials) publishes technical standards not only for textiles but for many other industries.

In the textile sector in particular;

• Physical tests

• Tensile strength

• Tear resistance

• Air permeability

• Beading

• Wear performance

It is widely used in these fields.

RELIGION

DIN (Deutsches Institut für Normung) is Germany's national standards organization.

Many older DIN standards still used in Europe today have been integrated into ISO and EN ISO systems over time.

Therefore, nowadays, laboratories frequently use:

• DIN EN ISO

• EN ISO

Standards are encountered in this format.

Why can the same fabric yield different results in ISO and AATCC tests?

This is one of the most misunderstood topics in laboratories.

For example, the wash fastness of a fabric is both:

• ISO 105-C06

as well as

• AATCC 61

It can be tested with.

However;

• Detergents used

• Bathroom volume

• Mechanical effect

• Washing time

• Adjacent fabric structure

• Evaluation criteria

They are different from each other.

Therefore, the same fabric can produce different results.

This is not a laboratory error.

This is due to differences in standards.

What systems should be found in an accredited physics laboratory?

In a modern physics laboratory, it is no longer sufficient to have only a few basic instruments.

The expectations of global brands are constantly increasing.

In a modern laboratory, typically:

Martindale AXYZ

• Abrasion Resistance

• Pilling Resistance

It is used for testing purposes.

It offers high sample capacity thanks to 11 independent testing stations.

Opti-Pill

• ICI Pilling Box

• Snagging

• Marks & Spencer Pilling Tests

It supports multiple methodologies such as these.

Random Tumble Pilling Tester

It is particularly preferred in pilling tests for the American market under the ASTM D3512 standard.

Opti-Air

• ASTM D737

• ISO 9237

It performs air permeability tests according to standards.

Elmendorf Systems

• Tear Strength

It is used in measurements.

What systems should be present in an accredited durability laboratory?

Fastness testing laboratories have evolved from being solely focused on washing fastness testing.

In a professional laboratory, typically:

Washtec

• ISO 105

• AATCC 61

It is used for washing fastness tests within the scope of this.

Durawash

Especially:

• Marks & Spencer

• Next

• H&M

Brands like these play a significant role in durability and repeated washing procedures.

Crocktec Auto

• Friction Fastness

It is used for testing purposes.

Perspirometer Systems

• Sweat Dysfunction

It is used in tests.

Light Fastness Systems

• Lightfastness

• Xenon Tests

It is used for.

What do brands expect from the lab today?

In the past, brands only requested test results.

Today, however, expectations are much higher.

Brands;

• Quick results

• Repeatability

• Digital data management

• Accreditation

• Global comparability

He/She wants.

A fabric is expected to produce the same result in Istanbul, Cairo, Dhaka, or Ho Chi Minh City.

Therefore, laboratory investments are no longer seen as merely equipment investments.

-----

The first step in establishing a successful textile laboratory is not purchasing equipment.

First step;

It is about accurately analyzing customers, brands, and the target market.

If you are only working for the European market, an ISO-based structure may be sufficient.

However, in today's global textile world, the most appropriate approach for many manufacturers is;

The goal is to create a flexible and future-proof laboratory infrastructure that can meet ISO + AATCC + ASTM requirements.

A well-planned laboratory does more than just control quality.

It accelerates product development, increases customer confidence, reduces costs, and provides the business with a sustainable competitive advantage.
