Horizontal and vertical combustion tester, which model is good? Ask for answer 10

These models have different corresponding design standards, and it doesn't matter if it's good or not! CZF-3 corresponds to GB2408-1996 "Test Method for Burning Performance of Plastics - Horizontal Vertical and Vertical Method"; CZF-5 corresponds to GB2408-2008 "Test Method for Burning Performance of Plastics Horizontal Vertical and Vertical Method", (its content is equivalent to the standard of UL94); CZF-6 corresponds to the GB T12960-1996 "Quantitative Determination of Cement Components" standard, and HVR-JT is the setting of some manufacturers for the model, and its corresponding design standard is consistent with UL94; JXW-056AB is the same as GB T8333-2008 "Test Method for Combustion Performance of Rigid Foam Plastic - Vertical Combustion Method". The relevant standards involved are in the technical information section of the official website of Nanjing Jionglei Instrument, and it is recommended that you can choose to buy the standard according to your actual needs.

Selection of hipot tester.

The most important thing to choose a withstand voltage meter is two indicators, the maximum output voltage value and the maximum alarm current value must be greater than the voltage value and alarm current value you need. In general, the standard of the tested product stipulates the value of the applied high voltage and the alarm judgment current value. If the higher the applied voltage, the larger the alarm judgment current, then the greater the power of the step-up transformer that needs to be built-up, and the power of the step-up transformer of the general withstand voltage meter is etc.

The maximum voltage can reach tens of thousands of volts. The maximum alarm current is 500mA-1000mA and so on. Therefore, when choosing a pressure tester, you must pay attention to these 2 indicators.

If the power is too large, it will cause waste, and if the power is too small, the withstand voltage test cannot correctly judge whether it is qualified or not. According to IEC414 or (GB6738-86) specified in the selection of the power method of the withstand voltage meter, we believe that it is more scientific. "First, the output voltage of the hipot meter is adjusted to 50% of the specified value, and then the test product is connected, and when the observed voltage drop is less than 10% of the voltage value, the power of the hipot meter is considered to be sufficient.

That is, if the voltage value of the withstand voltage test of a product is 3000 volts, first adjust the output voltage of the withstand voltage meter to 1500 volts and then connect the tested product, if the output voltage of the withstand voltage meter drops less than 150 volts at this time, then the power of the withstand voltage meter is sufficient. There is a distributed capacitance between the live part of the test product and the housing. The capacitor has a cx capacitive reactance, and when an alternating current is applied to the two ends of the cx capacitor, a current is induced.

The magnitude of this current is proportional to the capacity of the CX capacitor and the applied voltage, when the current is large enough or exceeds the maximum output current of the withstand voltage meter, the withstand voltage meter cannot correctly determine whether the test is qualified or not.

1. Turn on, the first interface has three test methods: horizontal method, vertical method and self, and the selection key of the point response enters the corresponding interface.

2. ta - the following value is the flame application time, you can directly click the number to enter the keyboard interface to modify the time.

3. The functions of the common keys of start, stop, gas, ignition, save, and timing are the same. Similarly, the position of the words "Horizontal and Vertical Burner - Vertical" is also the reset button, and clicking it will reset to the boot interface.

4. T1 is the first flame time, T2 is the second flame time, T3 is the flameless burning time to spread to the fixture and the bottom of the shop, and the corresponding style position at the lower end of the companion can be clicked to select the corresponding situation.

5. ta - flame application time. Intermittent time - the time it takes for the flame to return to the next auto-advance;

Number of cycles – i.e. the number of burns.

1) Clear Historical Data – Clicking Clear will clear all saved historical data.

2) The motor returns to turn off the gas - there are two options of "yes" and "no" in the switching state, select "yes", the system will turn off the gas at the same time as the motor returns to the spike bureau, and the gas should be turned on again in the operation interface before the next start, and the Bunsen lamp will be bright when you select "No".

3) Automatic ignition when the motor starts - there are two options of "yes" and "no" in the switching state. Only when the motor returns to turn off the gas and selects Yes, you can select "Yes", select automatic ignition, then the system will automatically turn on the gas ignition after pressing the start button three times and then automatically start the Bunsen burner.

50W UL94 horizontal and vertical fire test:

Go to the [500w Horizontal and Vertical Burning] screen.

1) Pull out the operating handle to make the burner (Bunsen burner.

Outside the seat, place the burner tube vertically, select the required combustion power (50W), and place the flow meter first.

Increase the gas flow slightly.

2) Press the [Burn Start] button to light the flame. Adjust the flowmeter knob, rotate the air conditioning device on the upper part of the Bunsen burner to adjust the height of the outer flame, adjust the adjustment knob of the air inlet under the Bunsen burner, adjust the height of the inner flame of the flame (20mm), and the two air intake knobs are adjusted by cooperating with each other to obtain the flame required by the standard. Flame regulation and temperature rise measurement are described in [Temperature Rise Measurement].
