Here is the core of what you’ll find inside the DIN 8570 B PDF. The standard defines three quality levels for weld imperfections:

The standard provides acceptance criteria, not a certification method. You still need trained NDT personnel (VT Level 2, RT, UT) to measure imperfections and compare them to the tables. Here is the core of what you’ll find
One of the most significant aspects of DIN 8573 is its role in bridging the gap between theoretical design and practical application. When engineers design a circuit board or a heat exchanger, they calculate expected loads and thermal stresses. DIN 8573 provides the verification mechanism for these calculations. For instance, the standard dictates specific sample geometries and testing speeds for tensile testing. This specificity ensures that data derived from a laboratory test is reproducible and comparable to results from other facilities. This reproducibility is the bedrock of the global supply chain; it allows a manufacturer in Germany to trust the quality of a component produced in Asia, provided both adhere to the same testing protocols.
