Several types of doors are available in the building industry, including hinged, sliding, or rolling doors, as shown indicatively in Fig. 1. The size of fire doors is variable ranging from one to several meters in width and height. In particular, the size of hinged doors is usually limited by the self-weight of the door leaf, while sliding and rolling doors can typically reach larger dimensions. Rolling doors exhibit the advantage of not requiring space in open configuration, and they are mostly preferred in cases of large openings within compartments of limited free space. However, they typically possess lower fire resistance than sliding doors, due to thickness limits imposed by the flexibility of door and the effect of restrained thermal expansion that becomes critical with increase of the door width. Therefore, sliding doors are more preferable in cases of compartments exhibiting large openings in which a high fire-resistant rating is required.

Based on the comparison between the standard and oversized doors (Test 1 and Test 2), it is evidenced that the fire resistance was not affected by the width opening of the door-leaf. This is mainly attributed to the boundary conditions of the examined doors which were similar in both cases. The contact with frame restrained sufficiently any out-plane movement which could introduce possible integrity failure due to gap openings. Moreover, as thermal expansion is not restrained in the horizontal direction (free to slide), the change of width dimension did not introduce any additional eigenstresses at elevated temperatures. Based on the comparison between the door tests inwards (Test 1, Test 2) and outwards (Test 3) the furnace, a remarkably more favorable fire behavior is encountered in the latter case because the wall covered the overlapping edges of door-leaf from direct fire exposure. Photos and thermographic views of the door specimens at 60 min after fire initiation are shown in Fig. 14. As it is evidenced, higher temperatures are developed at the door edges in Test 1 and Test 2 (orange color) compared to the corresponding locations in Test 3 (dark blue color).
This page offers links to downloadable versions of the complete ISO 639-3 code set, a language names index, the mapping of macrolanguages to individual languages, and the mapping of retired code elements to current code elements. The Code Set table and the Language Names Index table are formatted as tab-delimited, UTF-8 text files. These tables are also offered as ISO/IEC 8859-1 encoded text files, though these simplified encodings should not be considered normative. The remaining two files map between identifiers; they are presently encoded in ISO/IEC 8859-1, as currently all data in these tables can be correctly encoded in the more limited character set. The first line of each file contains the column names rather than the first row of data.
The "Ref_Name" column in the download tables contains a reference name by which this language is identified in the standard. The Reference Name is employed for ease of use of the code set, and does not imply it is to be preferred in any application to any other name that may be associated with the particular code element as given in the Language Names Index.
In ISO 639-2, there are multiple name forms for some identified languages. The ISO 639-3 code tables now include a language name index with multiple names associated many code elements (primarily in English forms or variant anglicized spellings of indigenous names). The reference name from the Ref_Name field of the main table is included as an entry in this table, thus every code element has at least one row occurrence in the Language Names Index table. The name appears in two forms, a "print" form used in most contexts, and an inverted form which fronts a language name root, e.g., "Isthmus Zapotec" and "Zapotec, Isthmus". Where there is no root part to the name, the Print_Name and the Inverted_Name contain identical strings. The Language Names Index may be downloaded by clicking the following link
Since the initial release of ISO/FDIS 639-3 and prior to the release of ISO 639-3, there was one list of retirements (deprecations), a correction to the alignment between ISO 639-3 and ISO 639-2. It is included in the Deprecated Code Element Mappings because it has been a source of confusion for users. The Deprecated Code Element Mappings table may be downloaded by clicking the following link.
