Technical purpose of product or process The MK4 structural supports include: - POT supports (EN1337‑5): these are structural devices used to support and transmit vertical and horizontal loads in structures such as bridges and buildings. They allow limited rotations around any horizontal axis, facilitating controlled movement of the structures and contributing to their stability and durability. They are divided into three individual products: PG, PM, and PF. - Spherical supports with PTFE (EN1337‑7): these are components used in load transmission and support systems in various industrial applications. These supports combine the structure of a spherical bearing with a PTFE layer, offering additional advantages in terms of performance and durability. They are divided into three individual products: SG, SM, and SF. - Guide bearings (EN1337‑8): these are components designed to provide control over the movement of structures, especially in bridges and buildings that require precise management of horizontal displacements and rotations. They consist of a single individual product: SK. - Elastomeric supports (EN1337‑3): these are devices used in the construction of bridges and other structures to transmit vertical loads and allow horizontal movements and rotations, contributing to the stability and durability of the structures. They are divided into three individual products: RL, RV, and RS. - Spherical and cylindrical supports made from specially developed material (ETA23/0869): these are structural components designed to offer advanced solutions in load support and transmission in various applications, thanks to the technology and advanced materials used in their manufacture. These supports are designed to offer superior performance under demanding conditions, thanks to their specially developed material, which gives them greater load capacity, durability, and wear resistance compared to other types of traditional supports. They are divided into three individual products: SG, SM, and SF.<hr>

1This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
2The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
