The durability of building structures is one of the most important requirements of modern construction. The durability of the structure depends on the operational durability of all the materials and elements that make up the structure. The durability of the insulation structure is determined by the preservation of the thermal insulation properties of this structure. The use of methods for assessing the operational stability of insulation materials allows you to get reliable results and save time and resources.

The project developed the climate control system, which will be used to study the durability of electronic components parameters
One of indicators quality of spacecrafts and systems, the requirement to which constantly increase, term of active existence which belongs to group of indicators reliability is and characterizes durability of spacecrafts. Value of term active existence is influenced by various factors among which essential value has durability of electronic equipment.
The factors affecting the durability of insulation systems and products based on mineral fibers are analyzed. It is emphasized that the ratio of acid oxides contained in the charge to the main oxides is the main factor affecting the stability of mineral fibers, as well as the energy intensity of their production. Hypotheses have been put forward and confirmed that the operational resistance of fibers depends on the content of heavy metals (their oxides) in the charge. The determination of the elementary composition of the stone wool samples was carried out using X-ray fluorescence. The conducted studies show that the fibers are safe in terms of radiation indicators, and their operational stability may be due to heavy metal oxides. It is confirmed that the durability of construction systems in which mineral wool products are used as thermal insulation is determined by the properties of mineral wool products, design competence and installation quality.
The article analyzes the methods of evaluation of calibration intervals of measuring instruments in the design. Describes recommended methods based on the use of indicators of reliability, in the examples it is shown that for electronic measuring instruments, their use may lead to inadequate results. Alternatively, a method based on the use of durability indicators, and examples confirming the possibility of its application in project evaluation of the primary calibration intervals.
