Tests and certification for manufacturers

Normative test facilities for a cabin class evaluation

SNDC has testing resources in compliance with international standards relevant for agricultural machinery (tractors, self-propelled machines …) and earth-moving machinery cabins.

EN 15695 standard

European standard EN 15695 aims to improve the protection of agricultural machine operators against substances harmful to health such as dust, aerosols and vapors during spraying work or spreading, providing protective qualities of the cab in different configurations. Four classes of cabins are defined by the EN15695 standard based on their protective qualities.

 

Classification cabins

SNDC Test facilities

SNDC has the means and expertise to test for evaluation and verification of compliance of agricultural machinery cabins, equipped with HVAC systems design by its Research and Development Department, in each of standard EN15695’s four classes.

From audit to cab marking

 

Classification Steps
Defining a class from 1 to 4 with measurement in test room

 

During evaluation work and verification, the cabin (or the whole machine) is introduced into a tests hall in order to proceed to the measurement of the concentration and thus define the containment efficiency of the cabin.

Answers to frequently asked questions about EN 15695 standard :





What is EN 15695 ?

EN 15695 European standard purpose is to limit the exposure of agricultural and forestry tractors drivers to hazardous substances such as dust, aerosol and vapours when applying plant protection products (PPP) and liquid fertilizers, by requiring a good protection level of the cabin.

How are agricultural machinery manufacturers concerned by this standard?

To ensure the driver’s safety, it is important to check the protective level of the cabin in the various work configurations, such as applying plant protection products or liquid fertilisers. Depending on the type of work performed, the cabin has to comply with one of the four categories stated by the standard.

What are the cabins categories?

The four categories define the level of cabin’s protection

Cabin category1
  • There is no protection.
Cabin category 2
  • The cab protects the driver only against dust but does not protect against aerosols and vapors.
Cabin category 3
  • The cab protects the driver against dust and aerosol but does not protect against vapors.
Cabin category 4
  • The cab protects the driver against dust, aerosols and vapors.

What should be the equipment level of the cabin?

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

Cabin category 2 :

The cabin is equipped with a Pressurisation system and a dust filtration of fresh air installed in a slot to prevent unfiltered air flowing into the cabin and allowing its replacement by the driver.

Cabin category3 :

The cabin is equipped with a Pressurisation system, a dust filtration of fresh air and a aerosol filtration installed in a new housing to prevent unfiltered air flowing into the cabin and allowing its replacement by the driver.

Cabin category 4 :

The cabin is equipped with a Pressurisation system, a dust filtration of fresh air, an aerosol filtration and a vapour filtration installed in a new housing to prevent unfiltered air flowing into the cabin and allowing its replacement by the driver.

Should I inform my client the cabin category installed on our machines?

Commercial documents must inform your client on the category of cabin equipping your machine.

 

The cab must have the appropriate category marking.

 

Moreover, the user manual should provide information on the level of protection of the cab on the use and settings of protective devices, on the maintenance work and how to reduce risk of exposure to dangerous substances.

Is it necessary to audit the performance of the cabin?

Depending on the category, the cab must be tested and must meet performance requirements:

For category 2 cabins

The Pressurisation system shall be at least to obtain a fresh filtered air flow of 30 m³ / h and a pressure of 20 Pascals if the cab is equipped with a pressure indicator, or 50 Pascals when the cab is not equipped with an indicator. Filtration of fresh air should be placed in a housing preventing unfiltered air into the cabin.

For category 3 cabins

Requirements are identical to those in category 2 but in addition, filtration aerosol type "PR" must meet the requirements of EN 14387 and an audit of the cabin containment efficiency must be performed.

For category  4 cabins

Requirements are identical to those in categories 2 and 3, including the assessment of the effectiveness of the cabin’s containment, but in addition, filtration vapors type "A" must meet the requirements of EN 14387.
