puce RCF (refractory ceramic fibre) : these belong to the group of man-made mineral fibres (MMMF). The RCF are vitreous aluminosilicates produced either from a mixture of silica (SiO2) and alumina (Al2O3) with or without the addition of zirconium (ZrO2), or from kaolin clay. Other oxides, such as those of boron (B2O3) and titanium (TiO2) are sometimes added in order to modify the mechanical and heat resistance properties. The applications of the RCF are mainly industrial, they are recognized as having high heat resistance (over 1000°C).
puce Record : data and information (occupation, industrial sector, type of product used, process, measurements...) derived from a file to form an information report sheet, which gives rise to a single record in the database. Several records can be derived from the same file. Note that the concept of a "record" has rather fuzzy edges, because it is the documentalists who decide how the information will be (put together).
