BS EN ISO 3611:2023

What is BS EN ISO 3611 - Design and metrological characteristics of micrometers about?

One in a series of international geometrical product specification standards, BS EN ISO 3611:2023 sets out the design and measuring characteristics of micrometers which are used to verify and inspect manufactured products.

Who is BS EN ISO 3611 - Design and metrological characteristics of micrometers for?

1. mechanical engineering companies and manufacturing organizations, particularly those in aerospace, defence, automotive, rail, nuclear, and medical devices
2. calibration and testing laboratories
3. instrument manufacturers

What does BS EN ISO 3611 - Design and metrological characteristics of micrometers cover?

BS EN ISO 3611:2023 provides the most important design and metrological characteristics of micrometers for external measurements.

1. with analogue indication
2. with digital indication: mechanical or electronic digital display.

Why should you use BS EN ISO 3611 - Design and metrological characteristics of micrometers?

1. It helps produce micrometers that can make extremely accurate external measurements.
2. It’s been updated to be more useful to users, specifically by now including default values for maximum permissible errors (MPEs), the introduction of which simplifies the process of periodic reverification for users.
3. Its use can increase confidence in products, making them more saleable and smoothing their entry into new markets.

BS EN ISO 3611:2023 contributes to UN Sustainable Development Goal 9 on industry, innovation and infrastructure.

What’s new about BS EN ISO 3611:2023?

This latest version of the document replaces and supersedes BS EN ISO 3611:2010, which will be withdrawn on publication of the 2023 edition. The major changes in BS EN ISO 3611:2023 are:

1. general design characteristics have been removed and reference to BS ISO 14978:2018 has been included
2. metrological characteristics have been clarified and modified
3. requirements for test methods have been provided
4. classification system of maximum permissible errors has been added.
