Let's continue with the previous one:


The test has only just begun. In addition to the temperature test, the environmental test also includes the following tests.


(4) Vibration test




The sample is subjected to vibration from the X\Y\Z axis in three directions on a vibration table. There will be a 0~100Hz sweep, 5mm amplitude and the test duration is 1h. Potential failures of electronic components are generally exposed within the vibration frequency range of 20Hz to 50Hz.

 

(5) Salt spray test

 

The samples are tested in a 5% sodium chloride brine solution at a pH of 6.5-7.2,a temperature of 35°C ± 2°C, and for a period of 8-24H. The test is passed if there is no abnormality on the appearance, no corrosion on the surface, and no rusting of the screws.

 

 

3. Fatigue test

 

Button press fatigue test

 

Generally speaking, the button life on Olight torch is up to 50,000 presses. Every newly developed torch sample need a machine press test of tens of thousands of times.


 


When the key life test machine is activated, the torch's button is subjected to a high frequency of presses, 40-60 presses per minute, and this press frequency is adjustable.

 

In addition to the button press fatigue test done for conventional torches, some torches with rotary switches require a rotary fatigue test, and headlamps require a wire swing fatigue test.

 

To pass the test, the test specimen must function completely normally within tests and must not show any cracks, or the product must not crack or split and have a severely distorted appearance when visible to normal vision.

 

4. Reliability Test

 

Torches need to be able to withstand the rigors of the outdoor environment. Not only do they have to withstand drops and falls, but they also have to withstand wind and rain to ensure perfect performance, which often requires greater reliability. That's why a reliability test is essential for Olight torches!

 

The reliability tests include waterproof test, drop test, roller drop test, gunshot test, electrical stress aging test and anti-interference test.

 

(1) Waterproof test

 

IP stands for Ingress Protection and is the international designation used to determine the level of protection, which is made up of two numbers, the first for dustproof and the second for waterproof, the larger the number the better the protection.

 

Depending on the description of the protection level of the torch, different levels of water testing are carried out. For example, the highest level, IPX8, is tested underwater at 2 meters for 30 minutes.





The standard is met if there is no water inside the sample during the test time, the lens must not be misted with water, and functions such as switching on and off, gear changing, light spot and charging are all normal.

 

(2) Drop test

 

The drop test is carried out with the sample switched on. The drop test platform is a smooth, hard steel plate and the drop height is as required by the product definition book. If not required then the default is 1.5m. The number of drops: 6 times; the direction of the drop: 6 sides.



Standards to be achieved after the test: no cracks, no serious deformation in the appearance of the product under normal visual visibility; able to function normally. Reassembly is permitted, but no replacement parts are allowed.

 

(3) Roller drop test




Test conditions:


Speed: 10 revolutions per minute;


The number of revolutions: 100 revolutions at 0.5 m, 100 revolutions at 1 m

 

Standards: the light cannot flicker, shake or flash out during the roller drop; accessories can be reassembled but not replaced; the appearance of the sample is allowed to have some wear or cosmetic defects such as scuffs, but no cracks, serious deformation, etc.; the samples function properly; the batteries are not broken.

 

Every high-quality torch that comes to market has to go through a lot of tests. With aerospace-grade metal and advanced technology, most of Olight torches are able to pass the test. Once all the tests have been completed, they are ready for mass production.




Test Before Leaving the Factory

 

In order to achieve a satisfactory passing rate, Olight torches are subjected to various reliability tests on a sample basis before they leave the factory. One of the most important tests is the 'aging test'. But why do we need to do an 'aging test'?

 

Aging Test

 

There is an indicator in electronic products called product failure, which often occurs at the beginning and end of a product's life. Product failure is similar to human illness, as we are prone to various diseases when we are young and old. The aging test of the product is to let the product enter the healthy and prime period as soon as possible and avoid the early stage of the disease.

 


 

Olight torches are subjected to 100% charging and discharging aging test before leaving the factory, the process of charging and discharging aging is as follows: charging to full charge → charging check (check charging voltage, charging indicator, charging time, whether the charging process is normal, etc.) → aging (discharging time according to the model runtime) → discharging check (check torch temperature, switching, dimming, discharging time, whether the discharge process is normal, etc.) (etc.) → charging to shipping voltage → appearance and function check.

  

Through aging tests, we can check for defective products or devices and then further screen out failed or changed in value products, finding out quality defects or hidden dangers of products, eliminating early failures in products before normal use as far as possible, and fully guaranteeing that the products that leave the factory are of good quality. So you can believe that every torch that comes into your hands is a guarantee of quality.




That's it for today's lab introduction! If you want to know more about the tests, we will give you more details next time.
