Technical Aspects of the ASTM B280 Standard for HVAC Systems
The ASTM B280 standard regulates the production of seamless copper tubes intended for use in high-load HVAC circuits and industrial refrigeration equipment. These products are optimized for the installation, maintenance, and retrofitting of refrigerant lines.
Engineering note: for the design of brazed joints in climate control systems, refer to the requirements of the ASME B16.22 standard, and the methodology for piping assembly via brazing is detailed in the ASTM B828 specification. The selection of solders for hermetic connections is regulated by the ASTM B32 standard.
EV Group China supplies copper tubes manufactured from the following alloy grades:
| Copper Alloy (UNS) | Former Designation | Technological Description |
|---|---|---|
| C10200 | OF | Oxygen-free copper without residual deoxidants |
| C12000 | DLP | Phosphorus-deoxidized copper with low residual phosphorus |
| C12200 | DHP | Phosphorus-deoxidized copper with high residual phosphorus |
The specification uses two measurement systems: inch-pound and metric (SI). These systems are independent standards; mixing them within a single project is prohibited to avoid technical conflicts. Values stated in parentheses are for information only.
The provisions regarding testing safety (section 18.2.4) are advisory in nature. Engineering and technical personnel are required to ensure compliance with occupational health and industrial safety protocols when conducting product testing.
This international standard was developed in full accordance with the standardization principles of the WTO, ensuring the unification of quality requirements for copper rolled products in the global market.
