Protective gloves for users of plant protection products
Requirements and test methods for protective gloves for users of plant protection products. Hands and forearms should be protected from contact with these plant protection products. These requirements apply to gloves made of elastomer and polymer materials.

G1 gloves are suitable if the potential risk is relatively low. These gloves are not suitable for use with concentrated pesticide formulations and/or for scenarios where mechanical risks exist.

G2 gloves are suitable when the potential risk is higher. These gloves are suitable for use with both diluted and concentrated pesticides.
G2 gloves also fulfil the minimum requirements for mechanical resistance and are therefore suitable for activities that require gloves with minimal mechanical strength.

Protective gloves - Electrostatic properties
Additional requirements for protective gloves worn in areas where flammable or explosive atmospheres exist or may exist (see IEC 60079-32-1). It specifies a test method and requirements for performance, labelling and information on electrostatic dissipative protective gloves to minimise the risk of explosion. Antistatic protective gloves dissipate electrostatic charges in a controlled manner and ensure that electrostatic charging of the wearer is avoided. The wearer must be grounded accordingly. This requires the use of appropriate protective gloves, protective clothing, safety shoes and floor coverings.

AQL 0,65_
AQL 0,65

The AQL (Acceptable Quality Level) defines a precisely procedure at which a certain subset of a good is allocated for a sample. This sample is tested according to settled standards and specifications. From the received results, it is possible to draw conclusions about the quality of the goods. The higher the requirements for a product are, the more stricter are the predefined guidelines. The AQL is therefore a statistical method for determining the quality. Medical gloves must be aseptic and must comply with DIN EN 455. An AQL (Accepted Quality Level) of less than 1.5 is to be observed. The gloves are only tested for water resistance.
