SNDC EXPERTISE

Testing and certification for manufacturers

Normative testing facilities for evaluation of cabin categories

SNDC is equipped with testing facilities that comply with required international standards for cabins of agricultural equipment (tractors, self-propelled machines, etc.) and construction equipment.

EN 15695 Standard

The European standard EN 15695 aims to improve the protection of operators of agricultural machinery against substances harmful to health such as dust, aerosols and vapours during spraying or spreading work, by ensuring the protective qualities of the cabin in various configurations.

Four classes of cabins are defined by the EN15695 standard according to their protective qualities.

SNDC testing facilities

SNDC has the expertise and testing facilities to classify the cabins of agricultural machines, equipped with HVAC systems designed by its research department, in each of the 4 classes of the EN15695 standard.

Measurements in the testing room to define a class from 1 to 4

During evaluation and verification work, the cabin or the machine equipped with its cabin is brought into a testing hall in order to measure the concentrations and thus define the containment efficiency of the cabin.

EN 15695 standard FAQ:

What is the EN 15695 standard?

The European standard EN 15695 aims to improve the protection of the operators of agricultural machinery against substances harmful to health such as dust, aerosols and vapors during spraying or spreading work, by ensuring the protective qualities of the cabin.




From what date is this standard applicable?

The European standard EN 15695 has been applicable since May 2010.




How does this standard concern agricultural machinery manufacturers?

To ensure the protection of the operator, it is necessary to ensure the protective qualities of the cabin in various work configurations such as spreading or spraying. Depending on the type of work performed, the cabin must meet one of the four categories defined by the standard.




Do I have to inform my customer about the cabin category installed on our machines?

The commercial documents must inform your customer about the cabin category fitted to your machine. The cabin must be marked according to its category.

In addition, the user manual must provide information on the level of protection of the cabin, on the use and adjustment of protective devices, on maintenance operations and on methods of reducing risks of exposure to hazardous substances.




What are the cabin categories?

The four categories define the level of protection of the cabin:

  • Category 1 cabin

    The cabin does not provide any protection.

  • Category 2 cabin

    The cabin only protects the operator from dust, but not from aerosols and vapours.

  • Category 3 cabin

    The cabin protects the driver from dust and aerosols but does not protect them from vapors.

  • Category 4 cabin

    The cabin protects the operator from dust, aerosols and vapours.

How well equipped should the cabin be?

In addition to the ventilation, heating and air conditioning system, the cabin must have additional equipment depending on its category:

  • Category 2 cabin

    The cabin is equipped with a pressurization system and air filtration system installed in a housing that prevents unfiltered air from entering the cab. The driver must be able to replace the filter according to the instructions in the Operations & Maintenance Manual.

  • Category 3 cabin

    The cabin is equipped with a pressurization system, air filtration system and aerosol filtration system installed in a housing that prevents the passage of unfiltered air into the cabin and allows its replacement by the driver.

  • Category 4 cabin

    The cabin is equipped with a pressurization system, air filtration system, aerosol filtration system and vapour filtration system installed in a housing that prevents the passage of unfiltered air in the cabin and allows its replacement by the driver.




Is a cabin performance verification required?

Depending on its category, the cabin must undergo tests and meet performance requirements:

  • For category 2 cabins

    The pressurization system must allow a minimum filtered fresh air flow of 30 m3/h and an overpressure of 20 Pascals if the cabin is equipped with a pressure indicator, or 50 Pascals if the cabin is not equipped with an indicator. The air filtration system must be placed in a housing that prevents the passage of unfiltered air into the cabin.

  • For category 3 cabins

    The requirements are the same as for category 2, but in addition the type "P-R” aerosol filtration system must meet the requirements of standard EN 14387 and an evaluation of the containment efficiency of the cabin must be performed.

  • For category 4 cabins

    The requirements are the same as for categories 2 and 3, including the evaluation of the containment efficiency of the cabin, but in addition the type "A" vapour filtration system must meet the requirements of standard EN 14387.
