un38.3. The battery safety performance test report, and a full set of safety performance tests for various types of batteries according to various standards at home and abroad, so as to ensure product quality and safety for battery manufacturers and improve export capacity in line with various standards. Battery UN383. What are the test contents?
Edit t1. Altitude simulation test:
Under pressure 116kpa, temperature 20 5 conditions, storage for more than 6 hours, no leakage, exhaust, disintegration, rupture, combustion.
t.2 Thermal Test:
The high and low temperature impact test was carried out under the conditions of 72 2 and -40 2, the storage time was 6 h in the limit temperature, the high and low temperature conversion time was 30 min, the impact was 10 times, and the storage was stored at room temperature (20 5) for 24 h, and the total test time was at least one week.
t.3. Vibration test:
A reciprocating logarithmic swept sinusoidal vibration is completed from 7Hz to 200Hz within 15min, and 12 vibrations in the three-dimensional direction are completed within 3hThe logarithmic sweep is an acceleration of 1 gn from 7 Hz until the frequency reaches 18 Hz. Then keep the amplitude at 08 mm (total offset 1.)6 mm) and increase the frequency until the acceleration reaches 8gn (frequency is about 50 Hz). Keep the acceleration at 8gn until the frequency increases to 200 Hz.
t.4 Impact Test:
150g, 6ms or 50g, 11ms half-sine impact, 3 times in each mounting direction, 18 times in total;
t.5. External short circuit test:
At 55 2, the external resistance < 01 condition short circuit, short circuit time lasts until the battery temperature returns to 55 2 after 1h.
t.6 Crash Test:
9.1kg weight from 61 25cm high falls on the place with 158mm round bar on the battery, check the surface temperature of the battery.
t.7. Overcharge test:
Under the condition of 2 times the continuous charging current and 2 times the charging voltage, the battery is overcharged for 24h.
t.8. Forced discharge test:
The battery is connected to a 12V DC power supply in series, and the discharge current is used for forced discharge.
un38.3 updated the seventh edition, 38There are two partial revisions to Chapter 3:
In the summary of the test: 383.5(f)(ii) Replace "mass" with "mass of cell or battery quality;."
38.3.5 (f) (v) Change the original "model" to "the model of the battery or battery and, if the test summary is for a product containing a battery and a battery pack, the product model number shall be provided." The modifications and statements herein are more precise and clear;
In the title of chapter 38, the original words "relating to Class 9" were amended to read "relating to the transport of Class 9 substances and articles;".
In chapter 38, the words "Class 9" were replaced by "Class 9";
