Identification of devices with unique IDs – IEC 61406 / DIN SPEC 91406 and VDI 2770

Feature illustration of digital product pass acc. to DIN SPEC 91406 / IEC 61406 and VDI 2770.

This article aims to provide an overview of one of the latest trends in the process industry. The digital administration of product information!

In case you didn’t know about it, products in the process industry usually come with lots of technical documents. No matter how simple the product or project scope is, hundreds of paper pages are in demand to take it on.

In this context, the DIN SPEC 91406/IEC 61406 and VDI 2770 standards for identifying devices with unique IDs are crucial for the digital management of documentation and product information.

TA-Luft amendment – What will change for you as a plant planner and plant operator in the area of valves

Sustainable icon with chemical plant complies with TA-Luft amendment.

The Technical Instructions on Air Quality Control or TA-Luft governing Germany’s industrial plants were recently updated. The goal of the TA-Luft is to reduce emissions and improve air quality.

In this article I will give you an overview of the TA-Luft amendment and explain the specificities and requirements applicable to industrial valves. Furthermore, I analyze the changes to the old TA-Luft to identify challenges and solutions.

Plant operators and plant planners can’t miss out on this info to run compliant facilities.

Hydrogen valves and typical application challenges

Lamp with green tree and H2 symbol and typical hydrogen applications and challenges.

Modern hydrogen applications demand durable valves. Beside the challenges with the media hydrogen they also often have to operate reliably under high pressure or at extremely low temperatures. There are some challenges that the industries have to face. In this blog article, we describe relevant key data on hydrogen, hydrogen applications and hydrogen valves.

Impact of the revision of the TA-Luft on the valve industry

Man is testing a valve according to revised TA-Luft emission standard.

The revised TA-Luft Emission Standard will refer to ISO 15848-1 to protect the general public and the neighborhood. And to prevent harmful effects on the environment caused by air pollution. All that in order to achieve a high level of protection for the environment as a whole.

In my blog post, I would like to explain what impact this change will have on the valve industry.

Difference between NACE MR0175 and MR0103

What is the difference between NACE MR0175 and NACE MR0103? And how do they compare?

Last week I was asked again: “Why there are two specifications existing and what is the difference between NACE MR0175 and NACE MR0103?” This led me to think about whether this topic also concerns other end-users and therefore I have summarized all important key data in my current article.

Challenge of Design Verification Test (DVT/TAT)

In my professional career I have found that in practice there is often misinterpretation in understanding Design Verification Test (DVT). DVT is formerly known as TAT (Type Acceptance Test) – a Shell Specification (MESC SPE 77/300A).

In the industry, there are many different manufacturers offering valves meeting Shell requirements. Users should also find out if these valves also meet the full Shell MESC SPE 77/300A Specification. This misinterpretation made me write this post.

There is no reason to specify DIN 19213 instead of IEC 61518

EC 61518 (DIN EN 61518) is the global standard for Manifold-to-Transmitter Flange Connections. This standard has been issued in 2001. IEC 61518 is based on the German standard DIN 19213 (latest revision 1991 before superseded by IEC 61518). So, basically DIN 19213 is not anymore used with the exception of revision 1980, which is still specified in some standards. IEC 61518 has been prepared by subcommittee 65B and I was one of the subcommittee members. I am really surprised that DIN 19213 is still used after all these years, although there is no technical reason to specify this obsolete standard.
