ISO 9975:1990 PDF Download

ISO 9975:1990 standard provides detailed guidelines for the production and use of round non-alloy steel wires in locked coil mine winding ropes. The standard covers several key aspects.

Firstly, it specifies the dimensional tolerances for these wires, ensuring that they meet the required size and shape criteria. This is crucial for maintaining the integrity and functionality of the winding ropes in mining operations.

Secondly, the standard outlines the mechanical characteristics that these wires must possess. This includes factors such as tensile strength, elongation, and other mechanical properties, which are important for ensuring the durability and reliability of the winding ropes.

Additionally, ISO 9975:1990 sets forth the conditions that any coatings applied to these wires must comply with. Coatings can play a vital role in protecting the wires from corrosion and other environmental factors, and this standard ensures that the coatings meet the necessary requirements.

Finally, the standard provides guidelines for sampling and control processes to ensure the quality and consistency of the wires produced. This helps in maintaining the overall quality assurance of the manufacturing and application of these wires in locked coil mine winding ropes within the mining industry.
