Reliability test
Constant temperature and humidity
Temperature range: - 40 ～ + 100 ℃
Humidity range: RH 20%-98%
Cooling time: 55 minutes for + 20 ℃ to - 40 ℃
Meet the standards: GB / t2423.1, GB / T 2423.2、GB/T 2423.3、GB/T two thousand four hundred and twenty-three point four
Purpose: it is mainly used to test the adaptability of products to temperature. Such as: product working temperature, storage temperature, etc.
shock
Frequency range: 0-100hz
Amplitude: Max 3.0mm
Meet the standard: GB / t2423.10
Purpose: it is mainly used to test the mechanical anti-seismic capacity of products.
Drop Test
Technical indicators: the wings can be lifted and dropped
Height range: 40-150cm
Meet the standard: GB / t2423.8 GB/T four thousand eight hundred and fifty-seven point five
Purpose: it is mainly used to test the mechanical anti-seismic capacity of products.
Salt fog
Brine Replenishment: automatically replenish the brine in the brine preheating tank
Measuring cup: two measuring cups are collected at the same time
Meet the standard: GB / t2423.17
Application: mainly used for salt water corrosion resistance of structural parts.
Bent plug lead
Bending angle: 10 ~ 180 degrees
Bending times: 0-999999
Purpose: it is mainly used to test the bending ability of lead wire.
Experiment of insertion and extraction force
Purpose: This machine is suitable for the insertion force, pull-out force and life test of various connectors and connectors.
Main functions: it can display the continuous change value and peak value of the pulling force, and the number of times can be set, the speed digital display and adjustable, and the experimental stroke can be adjusted according to the size of the product.
The main indicators are as follows:
Number of times of plug and pull 0-999999 times
Speed range 0-50 times / min (half of the speed display value is the actual plug-in speed)
Pulling force range 0～50kgf
Adjustable range of stroke 0～8cm
Alternating cold and hot shock test
Temperature range: - 40 ℃ -- 150 ℃ Main technical indicators:
Temperature range: high temperature box: + 60℃～200℃；
Low temperature box: 0℃～-65℃； Temperature fluctuation: ± 2.0 ℃;
Main functions: the equipment is divided into three parts: high temperature chamber, low temperature chamber and test room. During the test, the object to be tested is completely static. The cold and hot temperatures are introduced into the test area by using the cold and hot air circuit switching mode to achieve the purpose of cold and hot shock test. The product repeatedly circulates high and low temperature, and the chemical change or physical damage produced by product expansion and cold contraction.
Halt experiment
Basic configuration (key indicators)
Very high temperature variability 60 ℃ / Min, combined with mechanical vibration
Manufacturer: USA (Chart)
Main functions: High Accelerated Life Test (HALT) and high accelerated stress screening (HASS), import halt in design verification stage& Hass test, through the application of comprehensive environmental stress, can excite the potential defects of products into observable faults. It is not a test carried out by simulating the actual use environment, but by artificial application of step stress. The test is carried out quickly when the stress is greater than the limit stress specified in the technical conditions, so as to find out the working limit and even the ultimate damage limit of the product.
IP rating
IP is ingress The abbreviation of protection, IP grade is for the protection level of electrical equipment enclosure against foreign body invasion, and its source is the Standard IEC of International Electrotechnical Commission 60529, which was also adopted as a national standard in 2004.
In this standard, for the protection of electrical equipment enclosure against foreign matters, the format of IP grade is ipxx, in which XX is two Arabic numerals. The first marking number represents the contact protection and foreign object protection level, and the second marking number represents the waterproof protection level. For the specific protection level, please refer to the table below.
IP is an international code used to identify the level of protection IP level is composed of two numbers, the first number is dust-proof; The second figure is waterproof, and the larger the number is, the better the protection is.
Dustproof grade
number Degree of protection definition
zero Unprotected No special protection
one Prevent objects larger than 50 mm from invading Prevent the human body from touching the internal parts of the lamp by accident Prevent the intrusion of objects with diameter greater than 50 mm
two Prevent objects larger than 12mm from invading Prevent fingers from touching the internal parts of the lamp
three Prevent the intrusion of objects larger than 2.5mm Prevent tools, wires or objects with diameter greater than 2.5mm from invading
four Prevent the intrusion of objects larger than 1.0 mm Prevent the invasion of mosquitoes, flies, insects or objects larger than 1.0 in diameter
five dustproof It can not completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of the lamp
six dustproof Completely prevent dust intrusion
Waterproof grade
number Degree of protection definition
zero Unprotected No special protection
one Prevent dripping water from invading Prevent vertical dripping
two When the slope is 15 degrees, it can still prevent dripping water from invading When the lamp tilts 15 degrees, it can still prevent water dripping
three Prevention of water spray Prevent rain water, or water sprayed vertically into the direction with angle less than 50 degrees
four Prevent splashing water intrusion Prevent water from splashing in all directions
five Prevent the invasion of big waves Prevent the invasion of water from big waves or spray holes
six Prevent the invasion of big waves The normal operation of lamps and lanterns can still be ensured under certain time or water pressure when they invade into water
seven Prevention of water intrusion Under certain water pressure, the lamp can work normally
eight Preventing the effects of sinking
IP（INTERNATIONAL The standards for protection are as follows:
1) By IEC (International ELECTROTECHNICAL International standard for protection and waterproof test drafted by commission: International Electrotechnical Commission Standard IEC five hundred and twenty-nine – five hundred and ninety-eight
2) National standard GB seven hundred – eighty-six
