This document summarizes a workshop on establishing a type approval laboratory. The workshop covered regulatory frameworks, test methodologies, and concepts for assessing conformity. Participants included regulators, standardization bodies, and network operators. Presentations were given on topics like safety, EMC, fixed and mobile networks. Breakout groups discussed the scope of equipment and standards for type approval. It was agreed to start with an independent testing facility and take a phased approach focused initially on essential requirements for user equipment and receivers. Establishing adequate normative frameworks and enforcement was identified as important to address issues like counterfeit devices.

Who needs a CE mark and how do I get one? It is EU law that every product that enters the European Union meet the CE Directives and applicable Standards. This mark can only be applied to your product when you have fully complied with all relevant Directives and Standards for the type of system you are marketing and and a Declaration of Conformity has been developed.
It is particularity relevant to people responsible for the design and installation of PROFIBUS and PROFINET networks as outlined in the PI Guidelines on Earthing and Bonding of PROFIBUS and PROFINET Networks.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.

Type Approval is ...
Type approval is granted to a product that meets a
minimum set of regulatory, technical and safety
requirements.
Generally, type approval is required before a product is
allowed to be sold in a particular country, so the
requirements for a given product will vary around the
world.

Testing of receivers
Assuring that the receivers comply with (future!) DVB-T
network characteristics
Two approaches are proposed:
One-time testing at TAL (testing of one type, preparing
a report, support in solving problems, database support
for Communication campaign)
Permanent testing – permanent platform for
compatibility and interoperability testing (DVB-T network
is a changing environment!) using all approved
receivers on the market

Scope of the Breakaway session
Decide upon TAL framework
Which user eqipment and network elements should be
type approved?
What test methodologies should be used?
Which standards & recommendations should the
equipment comply to?

Wrap-Up of the Breakaway Sessions – Common
R&TTE Directive is a good point of reference
Technology Independence is important
Phased approach is encouraged
The most problematic issues are to be addressed first
(i.e. user equipment, receivers)
(Harmonised) standards and their references to be
used wherever possible

Issues Identified
Counterfeit mobile terminals
- cannot be solved by means of TA as those terminals
enter the market illegally
Questionable quality of network equipment, i.e.
equipment not meeting the declared operation
parametres
- can be solved by menas of TA only to some extent

Cocluding Remarks
An independent testing facility is important for the
region.
Phased approach encouraged. Start with essential
requirements and then expand the scope based on the
demand
There is adequate regulatory framework but not
enough normative framework and, consequently, little
enforcement

Concluding Remarks
Fake phones issue cannot be solved by means of testing and TA
alone if they enter the market illegally, i.e. without TA
Operators and regulators should equip themselves with detailed
technical (protocols, architecture, testing) knowledge. Ideally by
menas of university courses and other “neutral” sources
Operators to concentrate on interoperability, performance and
QoS. Signalling monitoring essential
In the beginning, regulators to concentrate on essential
requirements

Why safety?
Electrical products are now the cause of 80% of all
fires.
Technology trend leads to reduction and minimization
of electronic circuits.
The concentration of elements and concentration of
electric power per mm2 is increasing.
Electrical products can fail and may not guarante full
life time.

How to build the test site
Prepare enough place for:
Warehouse for measurement and IUT equipment
Filtering the Internal AC main power and IT network
(safety fuse and separate distribution)
Long term tests (tests can take more than 1 month)
Temperature&humidy tests (to assure separate
place for noisy test equipment
(temperature&humidity chamber))
AC/AC or DC/DC variation
