PN (Polska Norma) are the Polish national standards published by PKN, the Polish Committee for Standardization. The PN-H branch covers metallurgy and metal products.
Why PN-H standards matter in testing
A PN-H standard defines material requirements and test procedures for steels and metal products used in the Polish market, including mechanical properties verified by tensile testing.
What PN-H standards cover
PN-H addresses steel grades and metal products — for example, weldable reinforcing steel — with mechanical acceptance tested on universal testing machines.
How to read a PN-H designation
PN designations use a branch letter and a number:
| Part | Example | Meaning |
|---|---|---|
| Prefix | PN | Polish national standard (Polska Norma) |
| Branch | H | Field branch (H = metallurgy) |
