The standard “DIN 22102 Textile layered conveyor belts for bulk goods”, published by the German Institute for Standardization (DIN), consists of the following sub-sections published under the same title:
The DIN 22102-1 standard contains requirements for conveyor belts designed for transporting bulk cargo. It focuses on belts made from one or more layers of woven textile fabric. This standard is part of a series on conveyor belts and is widely used in industries such as mining, agriculture, manufacturing, and logistics to ensure safety, durability, and performance.
This standard applies to textile-layered conveyor belts for general bulk material handling. It covers dimensions (e.g., width, thickness, layer structure), technical specifications (e.g., tensile strength, elongation, interlayer adhesion), and marking requirements (e.g., labeling for identification and compliance).
This standard defines band widths, strengths, and coating thicknesses. It specifies test methods for properties such as tear resistance and abrasion. It ensures that belts meet minimum performance criteria for safe operation under load.
The DIN 22102-1 standard is based on three fundamental principles: dimensions, technical specifications, and marking.
These requirements ensure that the belts are fit for purpose and verifiable in inspections, which are critical for industries under tight regulatory oversight.
Test Standards for Textile Conveyor Belts in Bulk Material Handling
In the world of industrial material handling, conveyor belts are equipment that ensures the smooth operation of processes in sectors such as mining, agriculture, manufacturing, and logistics. These belts, manufactured from textile layers, are particularly suitable for transporting bulk cargo such as ore, grain, or aggregates, and must withstand demanding conditions including continuous tension, abrasion, stretching, and exposure to environmental factors. Standardized testing is essential to ensure reliability and safety.
The DIN 22102-2 standard includes comprehensive test protocols for conveyor belts with textile layers, complementing the dimensional and performance requirements specified in the DIN 22102-1 standard.
The DIN 22102-2 standard focuses solely on test methodologies. It serves as a permanent standard filling the gaps left by European harmonized standards that did not fully address textile-based conveyor belts. By providing detailed and repeatable tests, this standard helps manufacturers, engineers, and inspectors verify that belts meet minimum safety and durability thresholds, ultimately reducing downtime and increasing operational efficiency.
This standard applies to general-purpose conveyor belts for bulk goods. Special belts for coal mining (DIN 22109 series) or steel cord reinforced types (DIN 22101) are not included in this standard.
The purpose of this standard is to define laboratory and field tests to evaluate the mechanical, chemical, and physical properties of the tapes. These tests ensure that the tapes can carry loads without premature failure such as delamination or cracking.
The DIN 22102-2 standard specifies sample preparation, equipment calibration, and acceptance criteria, and typically refers to standards such as EN ISO 252 for thickness measurement or EN ISO 37 for tensile testing. Tests are categorized as static, dynamic, and durability types, performed under controlled conditions (e.g., temperature of 23 ± 5 degrees Celsius, 50% relative humidity).
The main test categories are:
These tests are typically performed in batches: full-width samples for field-like simulations, or narrow strips for laboratory efficiency.
In the world of bulk material handling, conveyor belts are only as strong as their weakest links: typically, the connections where the belt ends are joined to form a continuous loop. Whether mechanically or chemically bonded, these connections must withstand the same demanding conditions as the belt itself: high tension, abrasion, stretching, and environmental stress.
The DIN 22102-3 standard addresses this critical issue by defining the requirements for permanent connections in textile conveyor belts used for bulk goods. This standard ensures that the connections maintain the integrity, safety, and performance of the belt. As part of the broader DIN 22102 standard series, it plays a significant role in industries such as mining, agriculture, and logistics, where downtime due to connection failures can result in unexpected expenses.
This standard applies to permanent joints in textile-layered (e.g., polyester-nylon or EP fabrics) conveyor belts used for bulk goods.
This standard covers hot and cold vulcanized bonding, the most common methods for textile tapes. It specifies the strength, durability, and flexibility requirements for the bonds. Test methods are employed to verify the quality of the bonds. The aim of this standard is to ensure that the bonds retain at least 80–100 percent of the nominal tensile strength of the belt and exhibit resistance to fatigue, abrasion, and environmental degradation.
