GENERAL REQUIREMENTS

EN ISO 13688:2013

This standard deals with the general requirements that all protective clothing must meet. The standardspecifiesgeneral requirements for ergonomics, innocuousness, durability, ageing, size designation and marking of clothing. Italso provides the information to be supplied by the manufacturer.

 

HIGH-VISIBILITY CLOTHING

EN ISO 20471

According to the standard, medium risk refers to lighting conditions during both daytime and nighttime (vehicle lights). This should be defined in a risk assessment, where the responsible party will determine if it is low, medium, or high risk and define which safety elements should be mandatory.

Workwear certified according to EN 17353 is suitable for employees who require visibility but do not work in areas where the workplace risk assessment mandates the use of personal protective equipment certified according to EN ISO 20471.

Class 1: Minimum required level of protection. Workers should be fully visible to both vehicle and machinery operators in situations where these vehicles do not exceed 30 km/h.

Class 2: Medium required level of protection. Workers must be fully visible in adverse weather conditions and in workplaces where machinery or vehicles operate at speeds of over 40 km/h (up to a total of 60 km/h); for example, workers working near traffic.

Class 3: Maximum required level of protection. For anyone working in places where vehicles travel at speeds starting from 60 km/h, such as highways, dual carriageways, or airports and their surroundings.

Three classes of high-visibility clothing are defined based on three different minimum areas of retroreflective, fluorescent, and/or combined material. Each of these classes provides a different level of visibility, with Class 3 offering the highest level of visibility both during the day and at night in most rural and urban environments. Users should select the required class based on a risk assessment specific to the location and situation where the type of protection described in the international standard is needed.

MINIMUM SURFACE AREA OF VISIBLE MATERIAL IN m2
  Class 3 Garments  Class 2 Garments Class 1 Garments
Background MATERIAL 0,80 0,50 0,14
Retroreflective MATERIAL 0,20 0,13 0,10
Combined MATERIAL - - 0,20

 

GARMENTS AND ACCESSORIES INTENDED FOR SITUATIONS OF MEDIUM RISK DUE TO LOW VISIBILITY

EN 17353

Garments and accessories intended for situations of medium risk due to low visibility. According to the standard, medium risk refers to lighting conditions during both daytime and nighttime (vehicle lights). This should be defined in a risk assessment, where the responsible party will determine if it is low, medium, or high risk and define which safety elements should be mandatory.

Workwear certified according to EN 17353 is suitable for employees who require visibility but do not work in areas where the workplace risk assessment mandates the use of personal protective equipment certified according to EN ISO 20471.

PROTECTIVE CLOTHING: PROTECTIVE GARMENTS FOR WELDING AND RELATED TASKS

EN 14404:2004+A1:2010

This international standard establishes essential minimum safety requirements and test methods for protective clothing used in welding and related processes (excluding hand protection).

The standard classifies the garment or fabric into two protection levels based on the number of molten metal droplets the fabric can withstand before the calorimeter temperature increases by 40°C.

EN 11611 CLASS 1

Minimum 15 drops.

Class 1 corresponds to protective clothing for lower-level welding tasks and situations that involve lower levels of splatter and radiant heat.

 

EN 11611 CLASS 2

Minimum 25 drops

Class 2 corresponds to protective clothing for higher-level welding tasks and situations that involve higher levels of splatter and radiant heat.

Tests must be conducted on components after they have been treated in accordance with the manufacturer's care label (tensile strength - must reach a minimum of 400N, tear resistance - must meet a minimum of 20N, burst strength, seam strength, dimensional change, leather requirements, etc.).

To determine the protection class, various tests are conducted.

 

Flame spread tests. The method used for these flammability tests depends on the foreseeable use risk.

Impact of molten metal droplets. These tests determine the temperature increase after a sample receives a specific number of molten metal droplets.

Heat transfer tests. These tests are used to determine the time it takes for a certain level of radiant heat to penetrate the sample.

Electrical resistance tests. These tests are used to determine the resistance, and therefore the amperage, that passes through the sample when subjected to a 100 V voltage.

PROTECTIVE CLOTHING WITH ELECTROSTATIC PROPERTIES ARC

EN 1149-5

This standard specifies the electrostatic and design requirements that protective clothing must meet to prevent the formation of sparks that could cause a fire.

These requirements may not be sufficient in oxygen-enriched atmospheres. This standard is not applicable to electrical voltages.

The marking shall comply with Standard EN13688 and include a pictogram as shown here.

The human body has a volumetric resistivity low enough to act as a conductor, and if insulated from the ground, it can accumulate electrostatic charges high enough to cause dangerous sparks.

Antistatic protective clothing is designed to prevent the accumulation of electrostatic charges that can lead to spark generation. A spark can cause a fire or explosion under certain circumstances.

MATERIAL AND DESIGN PERFORMANCE REQUIREMENTS

It specifies the requirements for materials and the design of electrostatic dissipative protective clothing used as part of a complete grounding system to prevent incendiary discharges. These requirements may not be sufficient in oxygen-enriched flammable atmospheres.

This standard is not applicable to protection against network voltage.

Protective clothing that dissipates electrostatic energy must be capable of permanently covering all materials that do not meet this specification during normal use. Conductive parts such as zippers, buttons, etc., are allowed if they are covered by the outer material during use.

 

PROTECTIVE CLOTHING AGAINST THERMAL HAZARDS OF AN ELECTRIC ARC

IEC 61482-2

This standard specifies the requirements and test methods applicable to the materials and garments of protective clothing for electrical workers against the thermal risks of an electric arc.

An electric arc can cause severe burns, blindness, or even death. The performance of the IEC 61482-2:2018 standard is divided into the following two classes:

Class 1: Effective protection performance against a 4kA electric arc.

Class 2: Effective protection performance against a 7kA electric arc.

Thermal Arc Protection:

_IEC 61482-1-1 _Elim (incident energy limit attributed to a product below which all product responses are below the Stoll curve) ≥ 3.2 cal/cm²

_ATPV (Arc Thermal Performance Value) ≥ 4 cal/cm²

_EBT (Energy Breakopen Threshold) ≥ 4

_IEC 61482-1-2           APC 1 (Arc Protection Class 1): 4 kA           APC 2 (Arc Protection Class 2): 7 kA
