What is DIN 49440:3-1989

DIN 49440:3-1989 is a technical standard developed by DIN (Deutsches Institut für Normung), the German Institute for Standardization. This standard specifies the classification and performance requirements for protective gloves against mechanical risks. It is important to understand this standard when choosing the right protective gloves for various industrial applications.

Classification of Protective Gloves

Under DIN 49440:3-1989, protective gloves are classified into four categories based on their resistance to mechanical risks:

Category I: Simple Design - These gloves offer minimal protection and are intended for activities with low levels of risk, such as gardening or cleaning tasks.

Category II: Intermediate Design - These gloves provide intermediate protection and are suitable for a wide range of tasks involving moderate risks, such as construction work or handling machinery.

Category III: Complex Design - These gloves offer high-level protection and are designed for activities with very high risks, such as handling toxic substances or working with sharp objects.

Category IV: Special Purpose Design - These gloves are designed for specific purposes, such as protection against extreme temperatures or electrical hazards.

Performance Requirements

In addition to the classification, DIN 49440:3-1989 also sets out various performance requirements for protective gloves. These include:

Abrasion Resistance: The ability of the glove material to withstand wear and tear.

Cut Resistance: The level of protection provided against sharp objects.

Tear Resistance: The ability of the glove material to resist tearing.

Puncture Resistance: The level of protection against punctures from pointed objects.

Impact Protection: The ability of the glove to absorb and dissipate impact energy.

Permeability to Water: The resistance of the glove to water penetration.

Compliance and Certification

When selecting protective gloves, it is important to ensure that they comply with DIN 49440:3-1989. Compliance with this standard guarantees that the gloves have been tested and meet the performance requirements specified. Look for gloves that carry the CE mark, which indicates compliance with relevant European standards. Additionally, consider the specific industry requirements and hazards to choose gloves that provide adequate protection for the intended task.
