New fire prevention guidelines for photovoltaic systems: immediate application

The new fire prevention guidelines for photovoltaic systems have come into force, with no transitional period from 1 September 2025.

The updates concern design, installation, operation, and maintenance, with particular focus on the fire performance of panels: UNI 9177 Class 1 is no longer accepted, only Class E (EN 13501-1 on Broof T3/T4 roofs) or Class CFV (CEI TS 82-89) are permitted.

The Low Voltage Laboratory starts the tests required by the new CEI EN IEC 61340-4-11:2025 standard

Istituto Giordano expands its laboratory services with the tests required by the new CEI EN IEC 61340-4-11:2025 standard.

The standard concerns the verification of the electrostatic properties of intermediate bulk containers (IBC composites) used for the transport of bulk goods, which are essential to ensure safety in environments at risk of explosive atmospheres.

With this addition, our Low Voltage Laboratory is now able to carry out all the required type, acceptance, and periodic verification tests, supporting both manufacturers and users in assessing the regulatory compliance of their IBCs.

Laboratory Testing or Product Certification?

In the construction products sector, there is still considerable confusion between laboratory testing and product certification. These are different concepts, with different purposes and implications, and they are not always both applicable.

Correctly understanding their meaning is essential to avoid technical and communication errors and to properly enhance the value of the product. We have addressed this topic clearly in our article.

Fire doors: EI or REI? CE marking or Ministerial Approval?

Fire doors are essential components for building safety, as they help limit the spread of flames and hot gases in the event of a fire. To ensure their effectiveness, these doors must undergo rigorous testing to verify their expected performance levels. Let’s explore the necessary tests, the reference standards, and why, in some cases, CE marking is mandatory, while in others, Ministerial Approval is still required.

New Test Bench for Punching Failure Tests on Self-Supporting Suspended Ceilings

We have developed a new test bench dedicated to testing self-supporting suspended ceilings, capable of realistically simulating the fall of detached masses from the slab.
The system allows for customized tests on ceilings with spans of up to 8 meters, using clay block masses with variable density and monitoring soffit deflection with precision instruments.
This innovation provides manufacturers and industry professionals with a reliable tool to validate design solutions and ensure the safety of renovation works.
