Certification of Wear Resistance for Harvesting Machines

Certification of Wear Resistance for Harvesting Machines

The agricultural sector is one of the most demanding industries when it comes to machinery usage. Harvesting machines, in particular, are subject to extreme conditions such as heavy loads, high speeds, and harsh weather conditions, which can lead to wear and tear on their components. To ensure that these machines continue to operate efficiently and effectively, manufacturers have implemented various certification programs to assess the wear resistance of harvesting machines.

What is Wear Resistance?

Wear resistance refers to a materials ability to withstand abrasive or erosive wear caused by friction between two surfaces in contact. In the context of harvesting machines, wear resistance is critical as it directly affects the machines performance, efficiency, and overall lifespan. A machine with high wear resistance can maintain its original dimensions and shape for an extended period, ensuring consistent quality and yield.

Importance of Wear Resistance Certification

Wear resistance certification for harvesting machines serves several purposes:

  • Ensures compliance with industry standards and regulations

  • Provides a benchmark for evaluating machine performance and efficiency

  • Helps manufacturers improve design and development processes

  • Facilitates comparison and selection among different machines


  • Certification programs typically involve rigorous testing procedures, including:

    1. Abrasion testing: Measures the materials resistance to abrasive wear under controlled conditions.
    2. Impact testing: Evaluates the machines ability to withstand sudden shocks or impacts.
    3. Fretting testing: Assess the materials resistance to wear caused by repeated small-scale movements.

    Types of Wear Resistance Certifications

    Several organizations offer certification programs for harvesting machines, each with its own set of criteria and standards:

  • ISO (International Organization for Standardization): Offers a range of certifications for wear resistance, including ISO 13752 (Abrasion testing) and ISO 4364 (Impact testing).

  • ASTM (American Society for Testing and Materials): Provides certification programs for various types of wear resistance, such as ASTM G65 (Abrasion testing) and ASTM F2797 (Fretting testing).

  • EN (European Standard): Offers certifications for wear resistance in accordance with European standards, including EN 13353 (Abrasion testing) and EN 13673 (Impact testing).


  • Key Considerations for Manufacturers

    Manufacturers must consider several factors when seeking certification:

  • Material selection: Choosing the right materials for machine components is crucial for achieving optimal wear resistance.

  • Design and development: Designing machines with wear resistance in mind can help minimize maintenance and replacement costs.

  • Testing procedures: Understanding the testing procedures and criteria for each certification program is essential for a successful evaluation.
