Audited Supplier Electrical Flame Resistance Equipment Solar Panels Combustion Materials Test/Testing Machine
1. Product Description
According to the standard UL790 Figure A1 and IEC 61730-1 Appendix A: Photovoltaic modules combustion test requirements and reference design. Simulated real conditions to evaluate the roofing material fire resistance, and can be used in the testing of the flame retardant properties of photovoltaic modules.2. Standards
UL790
3. Technical Parameters
| Power supply | AC 380V ± 10% / 50Hz. Not less than 50KW (gasifier customer original, here did not consider its power) |
| The test must be carried out in a closed room with an exhausting temperature | 10 ° C to 32 ° C |
| The gas source of the test flame | gas or liquefied petroleum gas (the gas with better quality is recommended if possible). 100KG / hour gasification station.Burner specifications: The inner diameter is 50 ± 0.5mm (foreign trade is 60.3), burner length: 1.120 ± 0.05m, and with a long 12.7 long spray hole 910. Both ends of the input gas to maintain uniform pressure within the tube, the air supply tube diameter 33.4mm, the nozzle can be easily removed. |
| Flame can be easily adjusted | adjusting the valve, adjustable from 150mm to 300mm |
| Flame application time | interval: 1 ~ 99 minutes 99 seconds can be preset. |
| With automatic ignition | |
| With gas flow meter and pressure gauge, pressure regulating valve | |
| Test platform | Test material placed therein, the size of about 3900 × 1000 mm (the actual size of the sample according to different part of the gap filled) |
| Platform test installation angle | maximum 127/300; tilt does not exceed 416mm / m |
| Simulated eaves and test bench tail panel | non-combustible material |
| Test bellows | about 762 × width 2130 × length of at least 2500, and the design has blades to ensure uniform air duct, without turbulence. At the specified place (UL790, Cl. 5.4), the wind speed at the three points shall meet the requirements of 5.3 ± 0.2 m / s in 10 minutes. 12 The shape of the flame at the time of combustion is triangular and about 0.9 m at the orifice; Shrinks to 0.152 meters at 1.3 meters at the edge and 0.6 meters to the flames (1.3 meters), at which point the temperatures at designated points (UL790, Cl.5.5) can reach 760 ± 28 \ C and 704 ± 28 \ C and make sure that it stays within this range for 10 minutes |
| Fan | air volume of about 200-1000m³ / min, the use of frequency control air volume |
| With the wind speed sensor | |
| With the length gauge | 0 ~ 1000 mm ± 1 mm, and measuring tape 5 m ± 1 mm |
| Control system can measure and display | Temperature: 0 ~ 1000 ºC ± 2%, equipped with K-type thermocouple. Time: 0 ~ 999S / 999min |
| Test process automatic control.Second, the computer software testing system | |
| Intelligent control system | together with well-designed test and sampling circuit, the user can more easily achieve the test project started, the test process control, test parameter settings |
| Various types of test data through the sensor sampling sent to the computer, the computer automatically calculated and processed can be stored or printed into a table (graph) | |
| A gas overpressure protection, leakage, overload, short circuit protection | |
| This equipment can take into account the flame diffusion test and the burning block test: | |
| Wooden pad, according to UL790 Figure 4.7, Figure 4.9 composite wood (Plywood) pad | |
| Burning test block with combustion A, B, each of the 10, C is 100 | |
| Burning material for Douglas fir Size and weight | A: 300 × 300 × 19.1 × 3, 2000g ± 150g B: 15×150×19.1×3,500 g±50g C:38.1×38.1×19.8,9.25g±0.25g |
| Burner igniter (standard burner) | Used to ignite A \ B \ C type of combustion block The temperature measured at 58.7 mm above the nozzle was 888 ± 28 \ C Keep nozzles away from other fans Fourth, the user-owned: 1, burning block drying oven: can be 40 ~ 120 \ C interval thermostat, can be scheduled to accommodate 60 C-block |
