Laboratory
The main field of activity of the Laboratory is the study of physical factors:
- Lighting research
- Measurements for determining the parameters of the thermal environment (microclimate)
- High Frequency Electromagnetic Radiation Measurements
- Measurements of industrial frequency electromagnetic field intensity parameters
- Determination of radiation from computers and video discs
- Measurements of vibration in the working environment
- Residential and Public Vibration Research, Determination
In the construction sector we can offer a wide range of services. According to the ''STR'' construction technical regulation which brings our laboratory and construction representatives together.
Control norms and adjust tools for better quality.
Audio Classification Protocol, Acoustic Measurements:
Static sound class setting
Before the commissioning of the building, the State Commission, in accordance with (STR 2.01.07: 2003), must determine the actual sound class of its or its parts, which is divided into A, B, C, D. To determine the sound class, acoustic measurements are performed. The values of the noise indicators are compared with the normative values.
Steam acoustic measurements must meet standards:
- LST EN ISO 16283-1: 2014
- LST EN ISO 717-1: 2013
- LST EN ISO 16283-2: 2015
- LST EN ISO 717-2: 2013
- LST EN ISO 16283-3: 2016
- LST EN ISO 717-1: 2013
- LST EN ISO 3382-2: 2008
- LST EN ISO 3382-2: 2008 / AC: 2009
Classification of building sound classes:
Comfort Class A - The design will ensure that at least 90% of the population will appreciate the acoustic overlay as very good or good
Class B - a class of improved acoustic comfort conditions.
Comfort Class C - a class of acceptable acoustic comfort conditions.
Comfort Class D - a class of inadequate acoustic comfort conditions.
Comfort Class E - Class of Limit Acoustic Comfort Conditions.
In accordance with the Construction Technical Regulation STR 2.01.07: 2003 for newly designed cottages, multi-apartment buildings, blocked residential buildings (more than one owner and partition), public buildings and some noise-sensitive non-residential buildings, the sound class shall be at least C Newly designed buildings nearing class A.
Laboratory:
Testing of barrier structures, facade, floor, door sound insulation parameters, stairwells and corridor reverberation time settings, environmental and engineering equipment noise measurements, apartment buildings and blocked buildings, Determination of tightness of buildings and other services.
