Description
The engineering center carries out work on the certification of products for compliance with the requirements of seismic resistance. The result of the work - test report or calculation certificate for seismic resistance (seismic resistance)
The basis for issuing a seismic resistance certificate is:
Earthquake Resistance Calculation
Seismic Resistance Test Report
Calculation of seismic resistance is carried out if:
the product is represented by the construction of multi-element systems and it is technically impossible to place the product on the shaker
product or its equivalent has been tested before
the product has no resonance from 1 to 30 Hz
The design method is applicable when issuing a certificate for seismic resistance:
modular transformer substations (BKTP)
heat exchange equipment
capacitive equipment
light metal building
pumping installations
!!! The design method is acceptable for products that do not contain electrical and electronic components. The design method cannot confirm that the product will be operational during and after seismic impacts. The ability of the product to work during and after the impact of an earthquake can only be shown by an experimental method - tests on vibration stands, with mandatory performance checks before, during (if required) and after impacts.
Tests on seismic resistance are carried out on:
Electrical products: transformers, equipment, low-voltage complete devices, power converting equipment, lighting equipment.
During (after) testing, the electrical equipment is supplied with voltage (current), the product is checked for performance.
Ventilation equipment: filters, fans, air conditioners
Pipe fittings: valves, valves, check valves, ball valves
During (after) testing, the valve is tested for operability by supplying water under pressure.
Electrical products: trays, shelves, strips, racks, corners
Tests are carried out when creating the load on the samples provided by the specifications. Before, during and after testing, the product is checked for the presence of deflections.
Cabling and wiring products
Fire Extinguishing Modules
After testing, the products are tested for operability by switching on the starter.
Instruments, navigation equipment, video surveillance, radio communications
During (after) testing, the operability of the product is checked in accordance with the specifications of the specifications.
The certificate of seismic resistance is issued for compliance with GOST 17516.1-90 (or GOST 30546.1-98) for electrical products.
The certificate of seismic resistance is issued for compliance with GOST 30546.1-98 for machines, devices and technical products.
A seismic resistance certificate - a voluntary certificate issued in the GOST R system may be issued for a batch or for mass production. The maximum period for which the certificate is issued is 3 years.
