Standards save lives

Our main focus lies on the safety of our customers. Therefore HB Protective Clothing products always conform to the latest versions of national and international standards. Additionally, material and garments run through several internal tests in order to ensure a maximum level of quality. By taking part in EN standard committes, and thanks to the cooperation with renowned certfication institutes and technical high-schools, our employees remain up to date with issues relating to conformity with standards at all times.

DIN IEC 61482-2 

Protective clothing against the thermal hazards of an electric arc – Parts 1-2 are test methods. Method 2: Determination of arc protection class of material and clothing by using a constrained and directed arc (box test).

This type of protective clothing is intended to protect the wearer against thermal effects of a defined electric fault arc and prevents continued burning. The clothing protects the wearer against a certain type of heat in connection with an electric arc. The heat can be convective and radiating, caused by splashes of molten metal, or also a combination of the two aforementioned hazards. The tested protective clothing does not replace electrically insulating protective clothing such as clothing in accordance with EN 50286:1999, „Electrically insulating protective clothing for work on low-voltage installations“. Complete personal protection also requires suitable protective equipment such as safety helmet/visor, protective gloves etc.

This is done to make them clearly visible in dangerous situations under all light conditions during the daytime and when vehicle headlights are shone at them in the darkness. This standard specifies performance requirements to be met by the protective clothing in terms of colour and retro-reflection, along with minimum surface dimensions and requirements to be met by materials used in the smallest possible garment size.

DIN EN ISO 11612:2008 

Clothing to protect against heat and flame

This international standard specifies the minimum requirements for clothing protecting against heat and/or flames. In a wide variety of fields of application, the wearer can also be exposed to convective, radiant or contact heat, as well as splashes of molten metal. Within the standard, letters A-F define the performance levels relating to the protective properties listed above.

DIN EN 13034 Typ 6:2005 

Protective clothing against liquid chemicals – Performance requirements for chemical protective clothing offering limited protective performance against liquid chemicals

This standard specifies the minimum requirements to be met by protective clothing against chemicals offering limited protective effect, including reusable protective clothing. Protective clothing against chemicals offering limited protective effect is for use where there is a possibility of exposure to minor chemical spraying, liquid aerosols or low-pressure spattering.

DIN EN 14058:2004 

Protective clothing – Garments for protection against cool environments

This European standard specifi es the requirements and test methods for wear behaviour of garments for protection against cool environments. Use of tested garments in environments with an air temperature of -5°C and higher. Identifi cation should include classifi cation of overall heat transfer resistance.

DIN EN 343:2003 

Protective clothing – Protection against rain

Specifies requirements and test methods for materials and seams used in clothing to protect against precipitation (e.g. rain, snowflakes), fog and ground humidity. Waterproofness and resistance to water vapour are the properties that must be tested and indicated on the label. The various classes for resistance to water vapour provide an indication for the recommended wearing time in different ambient temperatures.

EN 13758-2:2003 

Solar UV protective properties; EN 13758 Part 1: Method of test for apparel fabrics; EN 13758 Part 2: Classification and marking of apparel

The European standard 13758-1 defines the method for determination of permeability of ultraviolet solar radiation for textiles; EN 13758-2 sets out the classification and identification of the clothing. As solar radiation causes skin diseases, only covered surface areas are protected of type UV-A and UV-B radiation.

DIN EN 61340 

Protection of electronic devices from electrostatic phenomena

Protective clothing with this standard is suitable for the manufacture of products, which are sensitive to discharges of 100V or more. Persons with ESD protective clothing are therefore protecting products during the manufacturing process from electrical discharges, which can happen with clothing that is not suitable for ESD, e.g. through friction or electrostatic induction (magnetic field, field effects) and/or material separations, and are therefore preventing damage to the component.

DIN EN 471 

Warning clothing – Test methods and requirements

DIN EN 471 sets out requirements to be met by protective clothing which visually highlights wearers. This is done to make them clearly visible in dangerous situations under all light conditions during the daytime and when vehicle headlights are shone at them in the darkness. This standard specifies performance requirements to be met by the protective clothing in terms of colour and retro-reflection, along with minimum surface dimensions and requirements to be met by materials used in the smallest possible garment size.

ENV 50354 

Protective clothing against the thermal hazards of an electric arc – Parts 1-2 are test methods. Method 1: determination of the Arc Thermal Performance Value, indicating the maximum load which the material can withstand (ATPV test). Method 2: Determination of arc protection class of material and clothing by using a constrained and directed arc (box test).

Cleanliness classes

The cleanliness class achieved by the finished product is determined by the model design. Due to the nature of the production process, the finished garment must be washed by a professional laundry service prior to use in order to establish its suitability for a cleanroom environment.

A cleanroom is a room with a controlled atmosphere (achieved by filtration, overpressure) in which contamination is reduced to an absolute minimum. The cleanliness class of a cleanroom is determined by measuring the particle concentration of particle sizes in the air. The results indicate whether or not the particle concentration exceeds the concentration limit for the relevant particle sizes and can thus be used to determine the cleanliness classes.

Cleanliness classes differ dependent upon the applicable standard. However, they relate to one another in a specific way. The two most common standards are outlined below.
