30 national and interstate documents on standardization came into force in the beginning of November 2021. There are series of documents on refractories and refractory raw materials, synthetic rubbers, electrotechnical periclase.
Now we will elaborate on some of the documents that became effective for the first time.
GOST 23166-2021 «Window and balcony translucent enclosing сonstructions. General specifications»
Current standard is distributed on window and balcony blocks of various types of functional use, balcony glazing and it sets general requirements to their manufacturing and application.
This standard is a core document for a set of standards on certain kinds of goods and designs of goods independently of their manufacturing materials and component parts.
GOST 34740-2021 «DC high-speed circuit-breakers for subway rolling stock. Safety requirements and methods of control»
Current interstate standard covers automatic high-speed circuit breakers for further use in the subways. These high-speed circuit breakers are dedicated for the protection of power electrical equipment with a nominal voltage of 750 V of subway rolling stock.
High-speed circuit breakers must contain integral enclosure in their design. They also should be unpolarized with free trips and operative current should be regulated.
GOST R 59567-2021 «Tents. Fire safety requirements. Flammability test methods»
This document sets the methods for determining the flammability from energy-restricted ignition sources of textile and polymer materials for the tents as well as fire safety requirements for them. This national standard covers tents for children's camps of a tent type.
Textile and polymer materials for the tents are sustainable for flammability subject to the conditions stated in standard.
Special device should be used while making tests on determination of flammability of textile and polymer materials for the tents. Sizes and components of this device are described in GOST R 59567-2021.
