The task of the proposed semantics is of two kinds: a) translation of annotation structures to semantic forms; b) model-theoretic interpretation of semantic forms. Semantic forms are represented in a type-theoretic first-order logic. These semantic forms are then interpreted with respect to a model for part of the world to which an annotated language is referentially, or denotationally, anchored. NOTE The basic framework and content of this document is based on Reference [1].

- integral burners under the control of fully automatic burner control systems,
- closed system refrigerant circuits in which the refrigerant does not come into direct contact with the water or air to be cooled or heated,
- mechanical means to assist transportation of the combustion air and/or the flue gas.
The above appliances can have one or more primary or secondary functions (i.e. heat recovery).
In the case of packaged units (consisting of several parts), this standard applies only to those designed and supplied as a complete package.
The appliances having their condenser cooled by air and by the evaporation of external additional water are not covered by EN 12309.
Installations used for heating and/or cooling of industrial processes are not within the scope of EN 12309.
All the symbols given in this text are used regardless of the language used.
1.2 Scope of this Part 1 of EN 12309

This document specifies requirements and test methods for evaluation of the permanence and durability of writing, printing and copying on paper stored in libraries, archives, and other protected environments for long periods of time, in which the information recorded on paper must be retained but not necessarily the full artistic quality. It is applicable to: — images on white permanent paper according to ISO 9706 or ISO 11108; — recording obtained from pens, stamps, copying machines and printers (that can produce monocoloured and/or multicoloured images). It does not apply to: — documents stored under harmful conditions, such as high humidity that promotes microbiological attack, excessive heat, radiation (e.g. light), high levels of pollutants, or the risk of water damage (or water contact). Since documents might be kept in non-protected environments before being transferred to protected environments, resistance to water and light is, however, of importance; — legal documents, e.g. banking documents, where the authenticity is of primary interest; — documents where the information contents are influenced by small colour changes; — documents within the scope of ISO/TC 42, Photography.

IEC 60840:2020 is available as IEC 60840:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60840:2020 specifies test methods and requirements for power cable systems, cables alone and accessories alone, for fixed installations and for rated voltages above 30 kV (Um = 36 kV) up to and including 150 kV (Um = 170 kV). The requirements apply to single-core cables and to individually screened three-core cables and to their accessories for usual conditions of installation and operation, but not to special cables, such as submarine cables and their accessories, for which modifications to the standard tests or the setup of special test conditions can be necessary. This document does not cover transition joints between cables with extruded insulation and paper insulated cables. This fifth edition cancels and replaces the fourth edition, published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- Gas immersed cable terminations for use at rated voltages above 52 kV are required to be designed, type and routine tested in accordance with IEC 62271-209 in addition to the routine and type tests specified in this document.
- Requirements are introduced for composite outdoor termination insulators.
- The test cylinder diameters specified for the bending test (type and prequalification tests) have been modified in line with IEC TR 61901:2016.
- A low smoke halogen free oversheath material, designated ST12 is introduced.
- Additional tests under fire conditions are introduced: vertical flame spread, smoke density, acidity and conductivity, which shall be applied according to the fire performance declared for the cable.
- A test for water penetration in the conductor is added.
- In addition to tests on the outer protection of joints, type tests on the screen sectionalizing insulation of all accessories have been introduced.
