The battery is qualified with no disintegration, no rupture and no fire. It meets standards of UL 1642:2012, UL 2054: 2012, UN38.3(2012),GB 31241-2014... Today,we will introduce the operation process of Battery Crush Nail Penetration Test Chamber for you! Operation Process-- 5 steps1, Wiring connect the three-phase four-wire 380V power supply (the machine in the line code N for the zero line, yellow-green for the ground), turn on the power switch such as the display does not show, please switch any two phases of the three-phase fire line; at the same time connected to the gas source. 2,Select test mode in the control system Huda Battery Crush Nail Penetration Test Chamber is a three-in-one extrusion and three optional extrusion two modes (three-in-one extrusion for three conditions, while the implementation of any one condition first reach the test stop or start timing, time to reach the test stop, three optional extrusion is a choice of three conditions for the test). Note: strictly prohibited to use pressure beyond the load range, so as not to damage the pressure sensor. 3, Place battery according to the actual need to set the test conditions after pressing the door button, place the battery, battery positive to the direction of the fan, the battery is placed in the middle of the lower pressure plate position. 4, Test press the close button, close the door, set the test conditions according to the actual needs, press the start button. 5, Observe and end test after waiting three to five minutes,and seeing the chamber without smoke and fire. Then open the chamber to check the battery. If battery does not explode or fire, the test is over.ReadMore -

Lithium Battery Safety Testing
With the wide application of lithium batteries in the fields of communication and electronic appliances, our requirements for the safety performance, reliability performance and cycle life of the battery are getting higher and higher. In order to ensure the safety of lithium batteries, relevant organizations have formulated various safety testing standards for lithium batteries. 4 Kinds of Battery Safety TestingTesting standards generally divide the safety testing into the following 4 categories:1. Electrical test: over-charge, over-discharge, external short circuit, forced discharge, etc.2. Mechanical test: extrusion, acupuncture, shock, vibration, drop, etc.3. Thermal test: high and low temperature cycle, combustion, microwave heating, etc.4. Environmental simulation test: high altitude and low pressure simulation, salt spray test, etc. Battery Test Machines for Special TestingIn order to ensure the safety performance of the battery, check the unqualified battery and avoid the occurrence of battery safety accidents,different safety testings need different testing equipment. As a result, more and more lithium battery manufacturers have increased demand for battery safety testing equipment. External short-circuit testing requires a battery short-circuit test chamber. According to different standards, the short-circuit test chamber is divided into normal temperature short circuit and temperature-controlled short circuit. Extrusion, acupuncture, impact, vibration, drop, combustion, high-altitude and low-pressure tests all require professional battery testing machines. Huda provide professional lab battery test solutions for customers. Welcome to consultant!ReadMore -

What Need To Do When Using Salt Spray Test Chamber?
As an important testing equipment for corrosion resistance testing, Salt Spray Test Chamber has been widely used. When using Salt Spray Test Chamber,some details need to be paid attention to.1. The surface of the sample should be cleaned. The cleaning method can be selected according to the nature and contamination status of the sample surface. Note that the sample cannot be re-contaminated due to excessive or careless handling.2. The test sample covered with paint and non-metallic film cannot be cleaned and processed before the experiment.3. The incision of the test sample and the exposed part of the end face of the substrate should be covered with an insulating cloth.4. Large sample can be directly placed in the chamber or cut for testing according to the size of the test chamber.5. Small or special-shaped sample can be hung on the sample rack with glass hooks or painted cotton threads, never with metal hooks.6. Clean gloves must be worn each time when taking sample, and not touch sample directly.ReadMore -

Attentions for Using Constant Temperature And Humidity Chamber
Constant Temperature And Humidity Chamber can simulate the complex natural environment of low temperature, high temperature, high temperature and high humidity, low temperature and low humidity.It is suitable for product reliability testing in various industries such as plastics, electronics, food, clothing, vehicles, metals, chemicals, and building materials. When using Constant Temperature And Humidity Chamber, please pay attention to the following 7 points to prevent accidents and injuries.1 During operation, please do not open the chamber door, otherwise it may lead to the following adverse consequences.(1) The high temperature airflow rushes out of the chamber, which is very dangerous.(2) The inside of the chamber door still maintains a high temperature, causing burns.(3) High temperature air may trigger fire alarm and cause malfunction.2 Constant Temperature And Humidity Chamber must be safely grounded to avoid electrostatic induction. 3 The lights should be turned off at the rest of the time.4 On any section perpendicular to the prevailing wind direction, the sum of the area of the test load section should not be greater than one third of the working section there.5 Operator need to check the safety systems regularly,such as circuit breaker, over-temperature protection...6 If the heating test product is placed in the test chamber, please use the external power supply for the power control of the test product, and do not directly use the power supply of the machine. When putting high temperature samples into the test, attention should be paid that the time for opening the chamber door should be as short as possible.7 It is forbidden to test explosive, flammable and highly corrosive substances.ReadMore -
