Product Classification & Testing Items
According to the United Nations Recommendations on the Transport of Dangerous Goods, the classification rules for dangerous goods, battery products containing strongly acidic or strong alkaline electrolytes are Class 8 (corrosive) dangerous goods. Lithium batteries are Class 9 (Miscellaneous) dangerous goods.
The battery product safety testing items are divided into:
(1) Intended use: high-altitude simulation, temperature cycling, vibration, low-rate charging, etc .;
(2) Reasonably foreseeable misuse: external short circuit, heavy object impact, squeeze, mechanical impact, free fall, forced discharge, abnormal charging, thermal abuse, incorrect installation, over-discharge, overcharge, high rate charging Wait.
Hazardous Characteristics of Battery Products
Requirements for Laboratory Accreditation Guidelines
Battery products, especially lithium batteries, have the danger of spontaneous combustion and explosion during storage, testing and transportation. For battery testing activities or laboratories, we must first establish the laboratory’s own safety precaution mechanism and develop effective preventive measures. And it is implemented in every step of sample storage and testing to prevent potential safety hazards to the greatest extent possible.
Facilities & Environmental Conditions
During the testing of battery products, especially during short circuit, overcharge, forced discharge, extrusion, and thermal abuse tests, the risk of explosion and fire suddenly increases. At the same time, the battery charge and discharge detection cycle is very long. Therefore, it is necessary for the battery testing laboratory to take effective personnel protection, area isolation, fire smoke extraction, remote monitoring and other measures.
Battery Laboratory Fire Protection System
Battery testing items are often dangerous and have long cycles. At the same time, batteries are chemically hazardous and require special fire extinguishing agents.
Common fire extinguishing agents:
- Water fire extinguishing agent;
- Foam fire extinguishing agent;
- Dry powder fire extinguishing agent;
- Carbon dioxide fire extinguishing agent;
- Haloalkane fire extinguishing agent and so on.
These fire extinguishing agents have their own advantages and disadvantages, but not all of them are suitable for battery laboratories. Inert gas extinguishing agents are more costly. Therefore, it is more appropriate to configure an automatic fire alarm system and FM200 gas fire extinguishing system for centralized control of fires caused by batteries. Set up smoke and temperature detectors in each functional area, multiple methods (manual and automatic), multi-level control, high reliability.
Battery Laboratory Ventilation & Air Conditioning
According to the power mode of ventilation, it can be divided into the following two modes:
- natural ventilation
- Mechanical ventilation
In addition, mechanical ventilation can be divided into the following 2 modes:
- Local ventilation (this mode is used for battery detection)
- Fully ventilated
Smoke Extraction Measures in Battery Laboratory
The smoke exhaust measures can be divided into natural smoke exhaust and mechanical smoke exhaust. Mechanical smoke exhaust can be divided into local smoke exhaust and centralized smoke exhaust. The mechanical centralized smoke exhaust system usually consists of a smoke retaining wall, a smoke exhaust port, a fire exhaust valve, a smoke exhaust duct, a smoke exhaust fan, and a smoke exhaust outlet. For environmental protection, you can consider adding a dust collector before the smoke exhaust outlet to avoid direct discharge of toxic and harmful smoke and dust into the atmosphere.
Battery Laboratory Flameproof & Explosion-proof
Explosion Protection & Smoke Extraction of Battery Testing Equipment
Remote Control of Battery Testing Equipment
Because the battery is prone to explosion or even fire during the test. Not only should we pay attention to the quality and safety of battery products and improve the ability of battery detection technology, but also need to pay attention to the safety protection measures of the laboratory itself. As far as possible, avoid harm to the inspectors. Therefore, a safe battery testing device is very important.
Last but not least, we are a manufacturer of battery testing equipment and environmental testing equipment with 14 years of production and R & D experience. More importantly, we are very confident in the safety of our equipment. If you need battery testing equipment or environmental testing equipment, please consult us.
