What is BS EN 12735-2 - Seamless round copper tubes about?
BS EN 12735 is a series of European standards on copper and copper alloys that discusses the best procedures and specifications required for manufacturing high-quality seamless round copper tubes. BS EN 12735-2 is the second part of a series of documents on copper and copper alloys. BS EN 12735-2 specifies the requirements, sampling, test methods, and conditions of delivery for seamless round copper tubes, smooth or inner finned, used for heat exchangers and their internal connecting pipes in the manufacturing of refrigeration and air conditioning equipment.
BS EN 12735-2 is applicable to tubes with an outside diameter from 3,97 mm up to and including 219 mm.
NOTE: The tubes are supplied in straight length in the material conditions hard, half-hard or skin hard or as coils in the material conditions light annealed or soft annealed.
Who is BS EN 12735-2 - Seamless round copper tubes for?
BS EN 12735-2 on copper and copper alloys is relevant to:
- Manufacturer of seamless round copper tubes
- Manufacturer of air conditioner and refrigerator
Why should you use BS EN 12735-2 - Seamless round copper tubes?
Seamless round copper tubes can better handle oxidation and corrosion for longer periods ultimately giving air conditioners and refrigerators a longer lifespan.
BS EN 12735-2 provides information on the material condition, mechanical properties, and grain size, dimensions and tolerances, surface quality, test methods, inspection.
BS EN 12735-2 exemplifies the required mechanical properties, dimensions, and tolerances that help you achieve precision in terms of product functionality and specifications.
As the user of BS EN 12735-2, you can be ensured of the quality of the corrosion-resistant seamless, round tubes for air conditioning and refrigeration that minimize the risk of leakage, corrosion, and contamination. As a result, BS EN 12735-2 takes into account the safety and protection of the product end-user while also prolonging the service life of the copper and copper alloy seamless tubes. BS EN 12735-2 provides you with comprehensive information useful throughout the process of production.
What’s changed since the last update?
BS EN 12735-2:2016 supersedes BS EN 12735-2:2010 which is withdrawn. In comparison with the first edition of EN 12735-2:2010, the following significant technical changes were made:
- The size range of the outside diameter has been increased from 3,97 mm up to 219 mm
- Dimensions and tolerances for smooth tubes have been modified in Tables 2, 4 and 5. The tolerances given in Tables 3 and 6 have been added
- Nominal outside diameters have been added to Table 1
