BS EN ISO 4499-1:2020

What is ISO 4499‑1 about?

ISO 4499‑1 is the first part of a series of documents on hard metals. ISO 4499‑1 specifies the methods of metallographic determination of the microstructure of hard metals using photomicrographs.

ISO 4499‑1 specifies information on photomicrography techniques and their procedure.

Who is ISO 4499‑1 for?

ISO 4499‑1 on the metallographic determination of microstructure is relevant to:

• Metallurgist
• Mechanical engineer
• Metal industries
• Metallographic test lab

Why should you use ISO 4499‑1?

A micrograph or photomicrograph is a photograph or digital image taken through a microscope or similar device to show a magnified image of an object.

ISO 4499‑1 provides information on electron backscatter diffraction (ebsd), preparation of testpiece section, metallographic preparation required to perform photomicrography.

As a user of ISO 4499‑1, you get information on photomicrography which helps you to determine the microstructure of hard metals, this helps the user to improve the physical properties of metals including corrosion resistance, strength, toughness, ductility, and hardness. ISO 4499‑1 helps the user to improve the quality of metal and widen the market reach for the product.

What’s changed since the last update?

BS EN ISO 4499‑1:2020 supersedes BS EN ISO 4499‑1:2020, which is withdrawn.

The main changes compared to the previous edition are as follows:

• In Normative references and Grinding: reference to ISO 3878 has been removed
• An apparatus (4.3) Electron Back Scatter Diffraction (EBSD) has been added
