EN 14125 is a European standard that primarily addresses the requirements for high-density polyethylene (HDPE) pipes used for gasoline and other petroleum products. These pipes are commonly utilized at gas stations and fuel storage facilities to ensure safe and effective fuel transfer.

The main contents of EN 14125 include:

1. Material Requirements: The standard specifies the performance requirements for HDPE materials, including chemical resistance, temperature resistance, and impact resistance, ensuring that the pipes can operate normally under various environmental conditions.

2. Performance Testing: Pipes must undergo a series of performance tests during the manufacturing process, including pressure tests, tensile tests, and corrosion resistance tests, to verify their safety and reliability when transporting liquids such as gasoline.

3. Environmental Adaptability: The EN 14125 standard considers the performance of pipes under different environmental conditions during the design and manufacturing process, ensuring their ability to withstand external factors such as temperature changes and soil corrosion.

4. Safety: The standard emphasizes safety measures for pipes in the event of leaks or damage, ensuring that issues can be quickly identified and addressed in case of an accident, thereby reducing risks to environmental and personal safety.

5. Certification and Marking: Pipes that comply with the EN 14125 standard must undergo certification and be marked with relevant information, enabling users and regulatory authorities to easily identify their compliance.
