The AD 2000 Code relies on a self-contained, high-quality concept for pressure equipment design. While the "W" series addresses general material guidelines, the specific includes:
Unlike the distinct separation found in the ASME Boiler and Pressure Vessel Code (Section VIII Div 1 vs. Div 2), AD 2000 utilizes a "Safety Factor" approach that balances traditional German engineering practices with the harmonized requirements of the Pressure Equipment Directive (PED) 2014/68/EU.

Easy compliance with the EU Pressure Equipment Directive. Quality: Consistent material properties and traceability.
The document is legally binding when manufacturers choose to build their pressure vessels in accordance with the AD 2000 Code.
First, let us break down the nomenclature. The AD 2000 Code relies on a self-contained,
For high-pressure applications where $D/s$ is low, W1 provides equations that account for the radial stress gradient. This prevents the underestimation of stress near the inner surface of the wall, which is critical for high-pressure autoclaves or reactors.

The document defines the minimum notch impact energy (KV in Joules) at specific temperatures. For example, for standard carbon steel, it might require 27J at 0°C or -20°C depending on the thickness. While the Merkblatt itself is not free, you
