Understanding ISO 4548-6:

ISO 4548-6 is an international standard that specifies the method for conducting a static burst pressure test on full-flow lubricating oil filters for internal combustion engines. This standard aims to assess the filter's ability to withstand high pressures, which is essential for the efficient and safe operation of engines.

Our Commitment to Quality: Rigorous Testing of Every Lot:

At our company, we prioritize product quality above all else. To ensure our customers receive products of the highest standard, we conduct ISO 4548-6 testing on every production lot. This meticulous approach guarantees consistent quality and reliability.

Impressive Results: Withstanding Pressures Over 50 Bar!

While the ISO 4548-6 standard mandates a minimum pressure of 15 bar, our products significantly surpass this requirement. Some of our products have demonstrated the capability to withstand pressures exceeding 50 bar! These remarkable results underscore the superior quality and durability of our products.

The Significance for Our Customers:

This exceptional durability translates into tangible benefits for our customers:

  • Extended Engine Lifespan: By withstanding high pressures, our filters protect engines from wear and tear, prolonging their operational life.
  • Enhanced Safety: The superior durability minimizes the risk of filter ruptures or leaks, which could lead to hazardous situations.
  • Reduced Maintenance Costs: High-quality products reduce the frequency of filter replacements, resulting in long-term cost savings.


Our company is dedicated to providing products that not only meet but exceed international standards. Through our rigorous ISO 4548-6 testing and the impressive pressure resistance demonstrated by our products, we are confident in our ability to meet and surpass our customers' expectations.
