DIN 22100 Articles and Materials Made of Synthetic Materials for Use in Underground Mines

The standard “DIN 22100 Substances and materials made of synthetic materials for use in underground mines”, developed by the German Institute for Standardization (DIN), consists of the following standards published under the same title:

• The standard "DIN 22100 Articles and materials made of synthetic materials for use in underground mines - Part 1: Conveyor belts - Hygienic requirements, testing, marking" describes the safety requirements for the hygienic properties and testing and marking of conveyor belts used in underground mines where filter self-rescuers are used as personal protective equipment.
• The standard “DIN 22100 Part 2: Steel-reinforced conveyor belts - Safety requirements, testing, marking” describes the safety requirements, testing and marking requirements for steel-reinforced conveyor belts, which are included among plastic operating materials and consumables used in underground mines.
• In the standard “DIN 22100-3 Part 3: Spiral air ducts - Safety requirements, testing, marking”, Plastic operating materials and consumables used in underground mines The safety requirements, testing and marking requirements for spiral ducts located between are described. Spiral air ducts are flexible plastic ventilation ducts equipped with a continuous spring steel wire spiral on the outside to keep the cross-section open and used for exhaust and forced ventilation.
• The standard “DIN 22100-4 Part 4: Straight air ducts - Safety requirements, testing, marking” describes the safety requirements, testing and marking requirements for straight air ducts among plastic operating materials and consumables used in underground mines.
• The standard "DIN 22100-5 Part 5: Pipes, pipe insulations and hoses - Safety requirements, testing, marking" describes the safety requirements, testing and marking requirements for pipes, pipe insulations and hoses, which are among the plastic operating materials and consumables used in underground mining. This standard specifies the safety requirements and tests for fire, hygiene and electrostatic properties of pipes, pipe insulations, hoses, foils, coated or uncoated fabrics (e.g. big bags), squeeze materials and squeeze mats used in underground mining.
• The standard “DIN 22100-6 Part 6: Sheets, coated/uncoated fabric, brattice materials and lag mats - Safety requirements, testing, marking” describes the safety requirements, testing and marking requirements for sheets, coated/uncoated fabric, brattice materials and lag mats, which are among the plastic operating materials and consumables used in underground mines. Brattice fabric is a thick type of cloth that is typically used in mining or on the construction site.
• The standard “DIN 22100-7 Part 7: Safety requirements, testing, marking” describes the general safety requirements, testing and marking requirements for substances and materials used in underground mining, which are among the plastic operating materials and consumables. This standard covers the safety requirements and tests for fire, hygienic and electrostatic properties of plastic operating materials and consumables used in underground mining. Equipment and materials made of plastics not specifically listed in this standard must be tested in accordance with the procedures specified in this standard, taking into account the relevant field of application. This standard does not apply to materials used as fillers from non-mining materials.

Synthetics used in underground mines must meet specific safety requirements. This set of standards includes requirements and test methods for fire protection, explosion prevention (electrostatic) and hygienic properties of pipes, pipe insulation and hoses.
