Due to the increasing occurrence of disasters and man-made disasters caused by Chinese people's impatience and eagerness for quick success, it is necessary to pay attention to safety issues in the field of fire protection. When installing and using fire emergency lights, it is necessary to arrange them reasonably based on the actual usage situation. It is necessary to use high-quality fire emergency lights and conduct actual testing in accordance with standard requirements. Below, Let's briefly explain the testing standards and projects for fire emergency lights, for your reference only
Safety standards for fire emergency lights:
(1) The production material of emergency lights must be difficult to burn materials (such as iron) According to national standards, fire emergency lighting fixtures must be equipped with three status indicators: "main power", "charging", and "fault" Main power indicator light: green, normally on, indicating that the main power and emergency lighting are connected normally; When not on, it indicates that the emergency light is not connected to the main power supply Charging indicator light: Red, only lit when emergency lighting fixtures are charging, indicating charging is in progress; After charging, it will automatically turn off Fault indicator light: Yellow, only lit when there is a fault in the charging circuit of the emergency lighting fixture, indicating that it should be inspected and repaired (3) According to the national standard, lamps must be equipped with a test button that simulates a power supply failure of the main power supply. When pressing this button, simulate cutting off the main power supply of the emergency lighting fixture, and the emergency lighting fixture will switch to an emergency state. Otherwise, it indicates that the emergency lighting fixture is not in emergency
(4) Charging time
All emergency lights are shipped in a discharged state. After installation, they must be charged for 20 hours before being discharged. The continuous discharge time cannot reach 30 minutes and needs to be repaired or replaced. After discharge, the battery must be fully charged within 24 hours. If it is not saturated, it indicates that the battery has failed
Fire emergency light inspection project content:
First, appearance quality inspection
The outer coating layer should be free of corrosion, detachment, blistering, five scratches, cracks, burrs and other mechanical damage. The shell and lampshade should be made of non combustible materials.
Testing method: Visual inspection
Secondly, installation firmness inspection
The installation should be firm and free from obvious looseness.
Detection method: Touch
III. Emergency lighting conversion function detection
After the normal AC power supply is cut off, it should smoothly transition to emergency working state, with a conversion time of no more than 5 seconds, and be able to continuously switch the lighting state 10 times.
Detection method: Simulate an AC power supply fault, observe whether the lighting state can be smoothly and continuously converted, and record the conversion time with a stopwatch4. Emergency working time and charging and discharging functions
The emergency working time should not be less than 30 minutes, and the discharge termination voltage of the lamp battery should not be less than 85% of the rated voltage, and there should be overcharging and discharging protection.
Detection method: After entering the emergency state, record the emergency working time with a stopwatch and measure the working voltage with a digital multimeterFifth, the illumination of emergency lighting
The illumination of emergency evacuation lighting should not be less than 0.5x.
Detection method: In an emergency state, turn on the emergency lighting for 20 minutes, use an illuminometer to measure its illumination at any point on the centerline of the channel, and record its small value The main purpose of fire emergency lights is that when a fire occurs and people are in a state of emergency with thick smoke, they need to bend down and escape the fire scene. Placing them on the ground makes it easier to see the emergency sign lights, providing the correct direction for everyoneFunction of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
1. The testing industry is fully covered, meeting different testing needs
2. Fully cover the laboratory and allocate localized testing nearby3. Engineers provide one-on-one services to make testing more accurate
4. Free initial testing, with no testing fees charged
5. Self service order delivery for free on-site sampling
6. Short cycle, low cost, and attentive service 7. Possess authoritative qualifications such as CMA, CNAS, CAL, etc 8. The testing report is authoritative and effective, and is generally used in China
