2.2. Temperature range of the chamber: -50 ºC to +160 ºC or wider

2.2.1. Temperature stability: no worse than ± 1 ºC in the steady state. The steady state is understood as the operating state of the chamber after reaching the set temperature and after the end of the stabilization period. The stabilization time should be indicated by the contractor and should not exceed 60 minutes from reaching the set temperature.

2.2.2. Temperature uniformity in the steady state: a. no worse than ± 2 ºC in the range -40 ºC to +120 ºC – confirmed by measurement in at least 9 points of the working space, b. for extreme temperatures below -40 ºC and above +120 ºC, a temperature uniformity of no worse than ± 3 ºC is allowed.

2.2.3. In the temperature range from -40 ºC to +120 ºC, the chamber should provide: a. a minimum average linear rate of temperature change measured in the working space of the chamber of 5 ºC/min for an empty chamber, b. a minimum linear rate of temperature change measured in the working space of the chamber of 2 ºC/min for a chamber with a passive reference load with a total heat capacity of not less than 200 kJ/K.

2.3. Humidity range of the chamber:

2.3.1. Control of relative humidity in the range from 10 to 95 %RH with an accuracy of no worse than ± 3 %RH in the temperature range from +10 ºC to +90 ºC

2.3.2. The chamber should allow control and stable maintenance of relative humidity at a level of 30% RH ± 5 %RH at 0 ºC, in the steady state, in order to realize demanding temperature-humidity cycles.

2.4. Floor load capacity: min. 500 kg/m2, uniformly distributed static load

2.5. Technological ports equipped with tight blinds:

2.5.1.2. Ø 25cm holes in the chamber walls – permissible square holes with a side of 25 cm

2.5.2.1. Ø 5 cm hole in the chamber wall at the height of the bottom of the working space – permissible square hole with a side of 5 cm

2.5.3.2. Ø 20cm holes in the chamber ceiling – permissible square holes with a side of 20 cm

2.6. Double-door with inspection windows with glass not permeable to UV radiation

2.7. Internal lighting of the chamber

2.8. Internal surfaces of the working space, including walls, ceiling, floor, and elements having contact with the chamber atmosphere, should be made of stainless acid-resistant steel in a grade not worse than EN 1.4404 / AISI 316L or an equivalent material with corrosion resistance in a chlorinated environment not worse than the indicated grade. The contractor should confirm the grade of the material used in the technical documentation.

2.9. Communication interface: LAN Ethernet and USB

2.10. Control: no less than 6 input/output ports

2.11. Minimum 6 universal analog inputs 0-10 V 4-20mA

2.12. The chamber software should, in addition to controlling the chamber, enable data archiving in the form of files: .csv, .txt or .xls. The chamber software should enable measurement of electrical energy consumption with recording to a file.

2.13. The use of eco-friendly refrigerants will be additionally scored as a evaluation criterion - The Purchaser will award points for the use in the refrigeration system of the chamber of a refrigerant or refrigerants with the lowest possible GWP, understood as the Global Warming Potential in accordance with the applicable regulations regarding fluorinated greenhouse gases. The contractor is obliged to indicate the type and quantity of the refrigerant(s) in the heating/cooling systems of the offered walk-in climate chamber.

2.14. The walk-in climate chamber must be manufactured by a manufacturer with an implemented and certified quality management system in accordance with the ISO 9001 standard or equivalent, and an implemented and certified environmental management system in accordance with the ISO 14001 standard or equivalent, covering the scope of activity of designing and/or producing climate chambers, environmental chambers, devices for simulating environmental conditions or equivalent devices. To confirm compliance with the requirement, the contractor is obliged to submit valid ISO 9001 and ISO 14001 certificates issued for the manufacturer of the offered chamber by an independent certifying unit, or equivalent documents confirming compliance with equivalent requirements in the scope of the quality management system and the environmental management system.

7. Calibration (Reference) Certificates

Calibration/Reference certificates issued by an accredited reference laboratory according to the ISO 17025 standard or an equivalent reference laboratory:

7.1. Calibration/Reference – The contractor must ensure calibration/reference of the walk-in climate chamber in the temperature and humidity range in the full operating range confirming compliance with the requirements indicated in 2.2-3. With particular consideration of the following points included in Table 1, noting that in the case of several values of relative humidity assigned to a particular temperature, confirmation of all values is required – at least 24 measurement points in total: On the date of signing the Final Acceptance Protocol, the calibration/reference certificates must be valid for at least 6 months.

7.2. Calibration/Reference - In the case of the requirement set out in point 2.2.3 b, it will be sufficient to present a protocol/report of tests confirming and documenting the temperature profile of the chamber with a clearly described method of conducting the confirming test.
