The subject of the order is the supply of a completely new dust chamber with vertical airflow for dust ingress resistance tests. The dust chamber must enable testing in accordance with the following methodologies, valid on the date of the offer submission: • PN-EN 60529 IP5X, IP6X; • ISO 20653 IP5KX, IP6KX; • PN-EN 60068-2-68 method La2 2. Test objects: The chamber will primarily test electrical and electronic devices or their enclosures with the following parameters: • mass up to 750 kg, • details with a small height (relative to the height of the chamber): max WxSxG [m] 1.5x1.5x2.5; • control cabinets/distribution boards with max dimensions: WxSxG [m] 2.2x1.0x2.5. The dimensions of the chamber should be appropriate to meet the requirements of the PN-EN 60068-2-68 standard (p.4.2.3) (the volume of the product should not be greater than 25% of the volume of the test chamber, and its base should not be greater than 50% of the horizontal working surface of the test chamber) 3. Required parameters of the dust chamber: The required parameters are listed in Table 1. Table 1, No. Required parameters 3.1 Dimensions of the working space: minimum WxSxG [m] 2.5 x 3.2 x 2.5, maximum WxSxG [m] 3.0x3.7x3.0 3.2 Double doors with an inspection window in at least one door 3.3 The floor surface of the chamber should be level with the laboratory floor to facilitate loading of details into the chamber (installation in a pit) 3.4 The chamber control system should allow settings for: • chamber interior temperature with a resolution of at least 0.1℃. • dust activation time (system start/stop time) including continuous or periodic mode (resolution 1s) • vibration system operation time (dust shaking system) (with a resolution of 1s) • test time (with a resolution of 1s in a range of at least up to 99h) • regulation of the negative pressure applied to the object with a resolution of at least 0.1kPa and pump operation time 3.5 Monitoring of humidity and temperature inside the chamber (continuous temperature recording, humidity measurement at least before starting the test). The chamber should have the ability to save data on a network drive or, if necessary, be equipped with a computer based on the latest Windows operating system 3.6 Dust drying system allowing temperature regulation and maintenance inside the chamber up to 80°C 3.7 Working space pressure compensation equipped with a replaceable filter 3.8 Dust concentration measurement system (the offer should include the basic assumptions of the system) 3.9 The dust distribution system should allow the use of at least the following dusts for testing: Arizona A2, Arizona A4, talc, Portland cement, mixture: 70% quartz sand, 15% chalk, 15% kaolin (according to NO-06-A107) 3.10 Within the scope of supply, a leakage tester should be provided to enable automatic leak testing of the tested objects with the following parameters: • pressure range from approximately -1 to 5 barg • leak measurement with a resolution of 0.0006 ml/min or better • the tester should have the ability to perform differential leak testing 3.11 If the offered leak tester does not ensure the performance of tests with applied negative pressure to the object, the supply should include an additional vacuum pump with flow and pressure measurement 3.12 The chamber should have the ability to remotely control the status of tests and parameters – connection to the LAN network and dedicated software 3.13 Chamber digital inputs/outputs: • at least 4 programmable digital outputs (programmed times of switching on/off from the moment of test start) • digital input enabling test start by another external device • digital output signalling the dusting phase • digital output signalling the set temperature • digital output signalling the alarm state 3.14 Passages with a diameter of 200mm - 2 pcs. 3.15 Chamber interior lighting 3.16 Detailed guidelines according to PN-EN 60068-2-68 method La2 3.17 Floor load capacity: minimum 750kg 3.18 The chamber should allow for the exchange of working dust, the offer should include a description of the method/system of emptying the dust and its loading 3.19 Warranty minimum 24 months 3.20 The contractor will provide in the offer the method of chamber construction, whether it will be delivered as a whole or in the form of modules (working chamber as a whole + engine room and control as subsequent modules), or whether the device will be integrated/assembled on site from components (panel casing, screwed from sheets, etc.). Information is necessary to ensure the appropriate parameters of the installation room (e.g. height/width of entrance gates and room) 4. Calibration Certificates (Patterning) The contractor, by implementing the subject of the order, is obliged to carry out patternings/calibrations and obtain Calibration Certificates/Patterning Certificates for all supplied measuring systems/measuring instruments within the implementation period of the subject of the order. Calibration Certificates/Patterning Certificates issued by an accredited laboratory patterned according to the ISO 17025 standard or an equivalent patterning laboratory. 5. All equivalent solutions are acceptable, provided that the tests can be carried out in accordance with the specifications given in point 1. 10. Delivery of the dust chamber The contractor is obliged to deliver the subject of the order, its transport, unloading, unpacking, placement, assembly and integration at the BOSMAL headquarters – details in Annex No. 9 “Scope of Responsibility”. 6. All entries in the specification of the order conditions indicating the type, trademarks, patent, origin, sources or a particular process should be read together with the words “or equivalent” 7. When the description of the subject of the order contains a reference to standards, technical assessments, technical specifications and technical reference systems, the Purchaser allows equivalent solutions 11. Training and commissioning: The contractor is obliged, before the acceptance of the subject of the order, to conduct training at the Purchaser's headquarters (at least 2 days).
