Protective Clothing and Workwear Standards: EN ISO 20471, 11612, 11611

Is workwear the same as protective clothing (PPE)?

No, and the difference lies in the design purpose. A garment designed and made to protect the wearer against a specific hazard is personal protective equipment (PPE; Turkish documents write KKD). Under Turkey's Regulation on the Use of Personal Protective Equipment in Workplaces (Official Gazette, July 2, 2013, no. 28695; in Turkish), an employer turns to PPE when a risk cannot be prevented or sufficiently limited by technical measures or work organization (art. 5), and the risk assessment decides which garment is needed (art. 7).

Ordinary workwear: a specification instead of a standard

Ordinary work clothes and uniforms not made specifically to protect workers' health and safety are outside that regulation (art. 2/2-a); the buyer sets quality criteria in its own specification. For makers of ordinary workwear and uniforms, which need no PPE certification, see workwear and uniforms.

Turkish Hard Coal Enterprises (TTK) shows what such a specification looks like. Its 2025 denim workwear specification does not tie the garment for workers in above-ground workshops to a protective clothing standard or class; it defines the fabric in measurable values:

Assurance comes from proving the fabric values with a report from an accredited laboratory or official body, not from a standard class. The 11 oz is about 373 g/m² (1 oz/yd² = 33.906 g/m²; see the fabric GSM calculator). Certificates such as OEKO-TEX show a product's chemical safety, not its protective performance (textile certifications guide).

Protective clothing: CE marking and risk categories

Turkey's Personal Protective Equipment Regulation (Official Gazette, May 1, 2019, no. 30761; in Turkish) binds manufacturers, importers and distributors: design to the essential health and safety requirements, conformity assessment by risk category (arts. 19-20), EU declaration of conformity and CE marking (arts. 16-18). It was prepared taking Regulation (EU) 2016/425 into account (art. 45).

Annex 1 sorts PPE into three risk categories. Category I covers minimal risks, such as superficial mechanical injury. Category III covers risks with very serious consequences such as death or irreversible damage to health (hot environments comparable to air at 100 °C or more, falls from height, electric shock). Category II covers the rest.

Conformity assessment follows the category (art. 20). Only category I allows self-declaration based on internal production control, with no notified body involved. In category II, a notified body performs an EU type-examination; in category III, the product or the production process is monitored as well, and the notified body's identification number appears next to the CE marking (art. 18/3). This is general information as of October 16, 2026, not legal advice; consult a safety specialist or a lawyer for your situation.

Protective clothing and workwear standards at a glance

The last column shows whether the current edition is on the European Commission's harmonized standards list of September 4, 2026 (Regulation (EU) 2016/425). Turkey's regulation presumes that PPE meeting standards published in the Official Journal of the EU, and their harmonized Turkish equivalents (TS EN), meets the essential requirements (art. 15).

EN ISO 11611 and EN ISO 11612 are valid standards (EVS records show the 2015 editions as valid); they are only absent from the EU list. Ask a notified body and your safety specialist what that means for certification, and ask the supplier in writing which standard and edition the certificate rests on. See also the technical textiles guide.

EN ISO 20471: high-visibility classes

EN ISO 20471 sets requirements for high-visibility clothing that makes the wearer visible to vehicle and machine operators by day and under headlights in the dark. It specifies color and retroreflective (light reflected back toward its source) performance, the minimum area of materials and their placement; medium- and low-risk situations are outside its scope (EVS record).

The class depends on the minimum area of material on the garment (Centexbel):

The workplace risk assessment decides which class is needed. Color and luminance of the fluorescent background are also measured after UV exposure and washing, and dimensional change after care cycles must not reduce the required visible areas (Centexbel).

Sewing on reflective tape does not make a garment compliant: class, area, placement and a test report are needed, and the TTK specification asks for 3 cm tape without naming a class. For medium-risk situations a separate standard, EN 17353, covers garments and devices that make the wearer visible. ISO's catalog lists ISO 20471:2013 as due for revision (stage 90.92, February 1, 2024); the 2013 edition is still the one on the EU list.

Flame-resistant workwear standards: EN ISO 11612 and EN ISO 11611

For flame-retardant garments, called “yanmaz” (non-flammable) in everyday Turkish, two standards come up most: EN ISO 11612 for heat and flame and EN ISO 11611 for welding.

Is “non-flammable” workwear really non-flammable?

No. The standards' titles describe clothing against heat and flame and clothing for welding (EVS records); they promise no incombustibility. A garment documents performance measured under set test conditions, so “non-flammable” alone is not enough: you need the standard number, edition year and codes.

EN ISO 11612: codes A to F

EN ISO 11612 sets minimum performance requirements for clothing that protects against heat and flame (EVS record; 2015 edition). A garment carries code A1 and/or A2 plus at least one of B to F; for B to F the digit after the letter is the level reached, and a higher digit means a higher tested level (BIMEO, a test laboratory's summary, and Kübler, a workwear maker's page on the standard; secondary sources):

The limit values for each level are in the standard text. In a specification, write the codes you need, not just “EN ISO 11612”.

EN ISO 11611: welding garments

EN ISO 11611 sets minimum basic safety requirements and test methods for protective clothing worn in welding and allied processes. The garment protects against spatter, brief contact with flame and radiant heat from the arc; foot, hand, face and eye protectors are outside its scope (EVS record). BIMEO says the standard defines two classes: class 1 for less hazardous welding techniques and class 2 for techniques that produce more spatter.

ISO published a third edition of ISO 11611 on June 18, 2024, but the EVS record still shows only the 2015 edition; ISO's catalog also lists a final draft, ISO/FDIS 11612, to replace the 2015 edition. State the edition year in the specification and ask which edition the certificate rests on.

Antistatic workwear standard: EN 1149-5

The standard for antistatic workwear is EN 1149-5 (2018 edition). It sets material and design requirements for electrostatic dissipative protective clothing. The garment is designed for use as part of a totally grounded system in places where the minimum ignition energy of the environment is at least 0.016 mJ. It does not cover separate gloves and footwear, may not be enough in oxygen-enriched flammable atmospheres and gives no protection against mains voltage (EVS record).

An antistatic garment is therefore not a guarantee on its own: a product sold as “antistatic non-flammable workwear” rests on two standards, EN 1149-5 for electrostatic behavior and one such as EN ISO 11612 for heat and flame.

Rain clothing: EN ISO 24232 and the status of EN 343

EN ISO 24232:2025 sets requirements and test methods for garments and materials that protect against precipitation (rain, snow), fog and ground humidity (EVS record). EVS shows it valid from November 3, 2025, and EN 343:2019 withdrawn on the same date. On the EU list, EN ISO 24232:2025 appears from September 4, 2026 and EN 343:2019 leaves it the same day (Implementing Decision (EU) 2026/1971). You may still see EN 343 on older certified garments; check the date of the certificate and the edition it rests on.

How to read a protective clothing label and certificate

A label and its papers show what the garment was made to and who is responsible. The first three rows come from the Turkish PPE Regulation; the last is for the buyer to compare with the certificate.

EN ISO 13688 covers general requirements for protective clothing, including marking and manufacturer information, and is used together with product standards (EVS record). Fiber content labeling falls under textile labeling legislation (clothing label requirements). For sales to the EU, CE marking and the A.TR movement certificate answer different questions: CE shows conformity with PPE legislation, while the certificate shows the goods' free-circulation status in the Turkey-EU customs union.

How to choose and specify protective workwear

The steps:

1. Define the risk in writing. The workplace risk assessment says which hazard at what level (art. 7 of the 2013 regulation).
2. Write the standard's number, edition year and class or code in the specification. The table is a starting point; ask your safety specialist about class and code. “Suitable” or “equivalent” leaves the document request vague.
3. Check that the certificate covers the model and fabric you order. An EU type-examination is done on a type, so a fabric report alone may not be enough. The fabric is only part of a garment: EN 1149-5 requires material and design together, and EN ISO 20471 requires area and placement as well as color. Ask what conditions sewing thread, zippers, reflective tape and logos must meet.
4. Test samples. Comfort and mobility cannot be read from report values; trial the sample with wearers and have doubtful values checked at an independent testing laboratory.
5. Monitor series production. AQL inspection catches the rate of defective pieces; it does not measure protective performance, which needs laboratory testing.
6. If you sell to the EU, plan the category requirements, the notified body and the EU declaration of conformity from the start.
