As mentioned in the matrix report, the EN codes require a minimum 27 J (20 ft. lb.) absorbed energy for all pressure equipment. The ASME code for boilers (which always operate at elevated temperature), Section I, does not contain an explicit impact testing requirement. In fact, as explained in the report, there

Stainless steel has a relatively high coefficient of thermal expansion coupled with low thermal conductivity, at least compared with carbon steel. So, stainless steel expands rapidly with the input of heat that occurs during welding and the heat remains close to the heating source. Distortion can result.

Harmonized System (HS) Codes Among industry classification systems, Harmonized System (HS) Codes are commonly used throughout the export process for goods. The Harmonized System is a standardized numerical method of classifying traded products. It is used by customs authorities around the world to identify products when assessing duties and taxes and for gathering statistics.
