Eurocode 1 - Actions on structures - Part 1-9: Atmospheric icing

1.1 Scope of EN 1991-1-9 (1) EN 1991 1 9 gives principles and rules to determine the values of loads due to atmospheric icing to be used for following types of structures: - masts; - towers; - antennas and antenna structures; - cables, stays, guy ropes and similar structures; - rope ways (cable railways); - structures for ski-lifts; - buildings or parts of them exposed to potential icing; - special types of structures, such as towers for transmission lines and wind turbines. NOTE Atmospheric icing on electrical overhead lines is covered by EN 50341-1. (2) EN 1991-1-9 specifies values for: - dimensions and weight of accreted ice; - shapes of accreted ice. (3) EN 1991-1-9 covers types of icing, ice loads acting on structures, and falling ice considerations. NOTE For wind actions on iced structures, see EN 1991-1-4. 1.2 Assumptions The assumptions given in EN 1990:2023, 1.2 apply. EN 1991-1-9 is intended to be used with EN 1990 (all parts), the other parts of EN 1991 and EN 1992 (all parts) to EN 1999 (all parts) for the design of structures.

Fume cupboards — Part 9: Fume cupboards, ducted with filtered internal recirculation

This document specifies characteristics concerning the design and performance requirements together with type testing and on-site testing procedures especially for ducted filtration fume cupboards (DFFCs) not described in the other parts of EN 14175. Filters in DFFCs can be specific filters or a combination of filters dependent on the characteristics of the contaminants to be removed. This part of EN 14175 is related to and refers to other parts of EN 14175 regarding definitions, technologies, testing methodologies, design factors and functional aspects and is read in conjunction with these. This standard covers the specific layout version of ducted fume cupboards with integral filtration. These devices called ducted filtration fume cupboards can be designed to partially reuse filtered air for internal dilution. Therefore, the term “hybrid” fume cupboards is sometimes used. Fume cupboards with associated filters are considered as standard fume cupboards according EN 14175 1 to EN 14175 3. NOTE Their filter requirements, description and testing are listed in Annex A for information. The requirements for fume cupboards and filters for radioactive work are described in detail in EN 14175 8. Recirculatory filtration fume cabinets which return the filtered exhaust air back into the surrounding room are not part of this document but described in prEN 17242. DFFCs are not foreseen for work with pathogens. Appropriate microbiological cabinets are described in the EN 12469 series.
