Haida International Equipment Supplies Test Equipments of Solar Panel Industry

IP Series

For portable, outdoor and automotive electronics are waterproof testing requirements, internationally, IEC, MIL or ETSI as well as SAE have a corresponding test requirements.

IEC/EN60529 waterproof is divided into 9 grades (level 0 ~ Level 8), waterproof grade (e.g. ipx4-Waterproof class 4):

Level 0: Completely waterproof and unprotected.

Level 1: No harmful effects in vertical direction of drip.

Level 2: Vertical drip should have no harmful effect when the vertical surface of the housing is tilted in the 15° range.

Level 3: No harmful effects when pouring water in the 60° range of each vertical surface.

Level 4: No harmful effects to splash water to the shell parties.

Level 5: Water spray in all directions of the housing without harmful effects.

Level 6: Strong water spray in all directions of the housing without harmful effects.

Level 7: The water in the specified pressure is immersed in a specified amount of time and the inlet water is not harmful..

Level 8: The casing inlet water is not harmful after continuous diving according to the conditions agreed between the manufacturer and the user (should be more severe than levels 7).

Temperature & Humidity Series

In the natural environment, Temperature and humidity are inseparable two natural factors, Different areas due to different geographical location, the resulting temperature, humidity effects are also different. This test is used to confirm the suitability of the product for storage, transportation and use under temperature and humidity climate conditions. The degree of rigor of the test depends on the high/low temperature, humidity and exposure duration.

Test criteria for reference:

GB/T 2423.3IEC 60068-2-78GB/T 2423.4IEC 60068-2-30EIA 364MIL-STD-810F etc.

Thermal Shock Series

Haida Thermal shock test Chamber is divided into high temperature zone, low temperature zone, and test area, unique thermal structure of the box in each district. Shock test application of wind path switching mode to import temperature into test area, do hot and cold shock test. The three-groove hot and cold impact tester is used to test the adverse effects on the product due to the rapid change of high and low temperature in the way that the items to be measured are motionless. Applicable to aviation, military, naval, electrical, electronic, instrumentation, medical equipment, civil nuclear energy, institutions of higher learning, Scientific Research Laboratory, Commodity Inspection Arbitration, Technical supervision Department, Building Materials Ceramics, Petrochemical and other products, whole machine and parts of thermal shock impact test.

Salt Spray Series

Salt mist test is a kind of environmental test which uses artificial simulated salt fog environment to confirm the corrosion resistance of product or metal material by using salt mist test equipment. The degree of rigor of the test depends on the duration of exposure.

Laboratory simulation of salt fog can be divided into three categories: Neutral Salt spray test, Salt spray test of acetic acid, Copper salt accelerated salt spray test.

(1) Neutral salt fog test (NSS test) is one of the earliest applications in the field of accelerated corrosion test method. It uses 5% sodium chloride saline solution, the solution ph value is adjusted in the neutral range (6.5~7.2) as a spray solution. The test temperature is 35 ℃, which requires the sedimentation rate of salt fog to be 1~2ml/80cm/h.

(2) The Salt spray test of acetic acid (ASS test) was developed on the basis of neutral salt spray test. It is the addition of some glacial acetic acid in 5% sodium chloride solution, The ph value of the solution is reduced to about 3, the solution becomes acidic, The final formation of salt fog is also changed from neutral salt fog to acidity. Its corrosion rate is about 3 times times faster than the NSS test.

(3) Copper salt accelerated salt spray test (CASS test) is a kind of rapid corrosion test in foreign countries, The test temperature is 50 ℃, Salt solution to add a small amount of copper salts-copper chloride, Strongly induces corrosion. Its corrosion rate is about 8 times times that of the NSS test.

Test criteria for reference:GB/T 2423.17IEC60068-2-11,ISO4628-3, ASTM B117, JIS-Z2371, JIS-G3141, GJB 150.1, MIL-STD-810F, MIL-STD-883E etc.

UV Aging Series

UV Aging Test Project refers to the simulation of products in the actual use of the conditions involved in a variety of factors on the product aging situation of the corresponding conditions to strengthen the experimental process, uv aging test for sun-resistant and artificial light sources, mainly for non-metallic materials. Test simulates the damage of sunlight, moisture and temperature to materials, material aging includes fading, loss of light, reduced strength, cracking, peeling, powder and oxidation, etc. Ultraviolet aging test box by simulating sunlight, condensing, imitating natural moisture, samples are tested for dozens of hours or even days in a simulated solar ultraviolet light environment, can reproduce damage that can occur outdoors for months or years, and learn how many years after the product is used to age.
