Subject of the order is the delivery of a completely new dust chamber with vertical air movement for dust penetration resistance tests. The dust chamber must ensure the implementation of tests in accordance with the methodological standards valid on the date of submission of the offer as follows:• PN-EN 60529 IP5X, IP6X; • ISO 20653 IP5KX, IP6KX; • PN-EN 60068-2-68 method La2 2. Test objects: The chamber will mainly test electrical and electronic devices or their enclosures with the following parameters: • mass up to 750 kg, • details with small height (in relation to the height of the chamber): max WxSxG [m] 1.5x1.5x2.5; • control cabinets/distribution boxes 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-leaf door with inspection window in at least one leaf 3.3 The floor surface of the chamber should be level with the floor surface of the laboratory for easy loading of details into the chamber (installation in a pit) 3.4 The chamber control system should allow settings: • chamber interior temperature with a resolution of at least 0.1℃. • dust activation time (system activation / deactivation time) dusting including continuous or periodic mode (resolution 1s) • vibration system operating 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 the pump operating time 3.5 Monitoring humidity and temperature inside the chamber (continuous temperature recording, humidity measurement at least before starting the test). The chamber should have the ability to record data on a network drive or, if necessary, 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 requires the basic assumptions of the system to be specified). 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 In the scope of delivery, a leak tester should be delivered, allowing the implementation of automatic leak tests of the tested objects with the following parameters: • pressure range from approx. -1 to 5 barg • leak measurement with a resolution of 0.0006 ml/min or better • the tester should have the ability to measure differential leak 3.11 If the offered leak tester does not ensure the performance of tests with the applied negative pressure to the object, the delivery 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 starting the test) • digital input enabling the start of the test by another external device • digital output signaling the dusting phase • digital output signaling the set temperature • digital output signaling 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 the exchange of working dust, the offer should include a description of the method/system of emptying the dust and its loading 3.19 Guarantee minimum 24 months 3.20 The contractor will specify in the offer the method of construction of the chamber, 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.). The 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 patterning/calibration and obtain Calibration Certificates for all delivered measuring systems/measuring instruments within the implementation period of the subject of the order. Calibration 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 seat of BOSMAL – details in Annex No. 9 "Scope of Responsibility". 6. All entries contained in the specification of the order conditions indicating the type, trademarks, patent, origin, sources or a special process should be read together with the words "or equivalent" 7. When a reference to standards, technical assessments, technical specifications and technical reference systems appears in the description of the subject of the order, the Purchaser allows equivalent solutions 11. Training and commissioning: The contractor is obliged to conduct training at the seat of the Purchaser (at least 2 days) before the acceptance of the subject of the order.
