Fire resistance tests for service installations - Part 8: Smoke extraction ducts
oSIST prEN 1366-8:2023

This document specifies a test method for determining the fire resistance of smoke extraction ducts. It is applicable only to smoke extraction ducts that pass through another fire compartment from the fire compartment to be extracted in case of fire. It represents fire exposure of a fully developed fire.
This method of test is only applicable to fire resistant ventilation ducts (same construction) with the following classification according to EN 13501-3:
-   fire from inside and outside i ↔ o;
-   applicable to a pressure difference up to 500 Pa;
NOTE 1   It is assumed that the duct A test(s) in accordance with EN 1366-1 has been performed with an under-pressure of minimum 500 Pa.
-   with integrity (E) and insulation (I) criteria equal to or higher than the intended classification for the smoke extraction duct.
For the purposes of the test described in this document, the duct is referred to as duct C.
This test method has been designed to cover both vertical and horizontal smoke extraction ducts. A vertical system need not be evaluated to this method provided that:
-   both horizontal (ho) and vertical (ve) classification according to EN 13501-3 has been obtained for the ventilation duct, and
-   it has been tested in a horizontal orientation to this method.
If the ventilation duct in practice is only used for vertical applications in smoke extraction systems, only vertical (ve) classification is bound to be used and tested in a vertical orientation to this method according to EN 13501-3.
This test method is suitable for ducts constructed from non-combustible materials (Euroclass A1 and A2 according to EN 13501-1).
NOTE 2   Reaction with components of the duct can reduce the oxygen concentration and lead to misinterpretation of the calculated leakage rate.
This standard applies to four sided ducts only (with fire exposure on all four sides). Ducts that utilize elements of construction for one, two or three sides are not covered. An alternative test method for one, two and three sided ducts will be developed separately.

This document provides requirements, guidance and information for the design and fabrication of topsides structure for offshore structures, including in-service, pre-service and post-service conditions.
The actions on topsides structure and the action effects in structural components are derived from this document, where necessary in combination with other International Standards in the ISO 19901 series (e.g. ISO 19901-1 for wind actions - see 7.6.2, ISO 19901-2 for seismic actions - see 7.7) and ISO 19902 for fatigue design (see 6.7).
This document is applicable to the following:
—     topsides of fixed offshore structures;
—     discrete structural units placed on the hull structures of floating offshore structures and mobile offshore units;
—     topsides of arctic offshore structures, excluding winterization (see ISO 19906).
If any part of the topsides structure forms part of the primary structure of the overall structural system which resists global platform actions, the requirements of this document are supplemented with applicable requirements in ISO 19902, ISO 19903, ISO 19904-1, ISO 19905-1, ISO 19905-3 and ISO 19906.
For those parts of floating offshore structures and mobile offshore units that are chosen to be governed by the rules of a recognized classification society, the corresponding class rules supersede the associated requirements of this document.
This document also addresses prevention, control and assessment of fire, explosions and other accidental events.
The fire and explosion provisions of this document can be applied to those parts of the hulls of floating structures and mobile offshore units that contain hydrocarbon processing, piping or storage.
NOTE          Requirements for structural integrity management are presented in ISO 19901-9.
This document applies to structural components including the following:
—     primary and secondary structure in decks, module support frames and modules;
—     flare structures;
—     crane pedestal and other crane support arrangements;
—     helicopter landing decks (helidecks);
—     permanent bridges between separate offshore structures;
—     masts, towers and booms on offshore structures.
This document provides requirements for selecting and using a national building standard with a correspondence factor for determining the resistance of rolled and welded non-circular prismatic components and their connections.

Geographic information - Land Administration Domain Model (LADM) - Part 1: Generic conceptual model (ISO 19152-1:2024)
kSIST FprEN ISO 19152-1:2023

This document:
—     defines a reference Land Administration Domain Model (LADM) covering basic information-related components of land administration/georegulation;
—     provides an abstract, conceptual model with packages related to:
—     parties (people and organizations),
—     basic administrative units, rights, responsibilities and restrictions (RRRs),
—     spatial units,
—     a generic conceptual model (sources and versioned object);
—     provides terminology for land administration/georegulation, based on various national and international systems, that is as simple as possible in order to be useful in practice. The terminology allows a shared description of different formal or informal practices and procedures in various jurisdictions;
—     provides a content model independent of encoding, allowing for the support of various encodings;
—     provides a basis for national and regional profiles;
—     enables the combining of land administration/georegulation information from different sources in a coherent manner.
The following are outside the scope of this document:
—     interference with (national) land administration/georegulation laws with potentially legal implications due to the possibility of describing different types of systems but in the same notation;
—     construction of external databases with party data, address data, land cover data, physical utility network data, archive data and taxation data. However, the LADM provides stereotype classes for these data sets to indicate which data set elements the LADM expects from these external sources, if available.
This document provides the concepts and basic structure for standardization in the land administration/georegulation domain. It defines a general schema that permits regulatory information to be described. It also allows for the relationship to multiple parties and groups to be expressed together with a referencing structure so that sourcing of all information systems can be maintained. This document establishes the common elements and basic schema upon which more detailed schema can be established.
