Summary of three main standard test conditions for temperature shock test chamber

Summary of standard test conditions for temperature shock test chamber:

GJB150.5 "Civil Equipment Environmental Test Method Temperature Impact Test"

Test temperature: high temperature 70 ° C low temperature -55 ° C

Hold time: 1h or stable temperature, whichever is longer

Cycle number or number of impacts: 3 cycles

Conversion time: ≤5min

GB/T2423.22 Environmental Testing Part 2: Test Methods Test N: Temperature Change

Test temperature: The series of temperature values ​​provided by the standard are preferred (high temperature from 200 ° C to 30 ° C level 10, low temperature from -65 ° C to 5 ° C level 7)

Holding time: 3h, 2h, 1h, 30min, 10min (depending on the heat capacity of the product, if the relevant standards are not specified, choose 3h)

Cycle number or number of impacts: 5 cycles

Conversion time: 2~3min

MIL-STD-810F Method 503.4 "Environmental Engineering Considerations and Laboratory Testing Part II Laboratory Test Methods Temperature Shock"

Test temperature: tailored to the expected deployment

Hold time: true exposure time or temperature settling time (also depends on the heat capacity of the product)

Number of cycles or impacts: 1 time, 2 times, 3 times or more

Conversion time: try not to exceed 1min, if more than 5min, consider the necessity of this test.

The above are the standard test conditions for the temperature shock test chamber.

Technical parameters:

Special advantage:

Protected by patent No. ZL 2013 2 0354946.9, do not infringe

1. High strength ABS material, ultra-thin light head, integrated surrounded 4 group handle design, meeting laminar flow requirements, easy to operate

2. Intelligent spot control technology: Light intensity not change when spot size changed

3. Intelligent shadow control technology: when light was sheltered by surgeon head, correlated LED light will automatically darken, other LED lights which are not sheltered will increase brightness, compensate the illuminance loss in surgery field, provide a better shadowless rate, bring the perfect surgical lighting (optional)

4. Variety of Surgical environment lighting mode: bright, normal, endoscopic lighting mode; Base axis has ambient light lighting mode (optional)

5. Satlite oval hanging main arm, meet laminar flow requirement

6. Double control system (optional), Li battery (optional), electric focus adjustment system (optional), RGBW color adjustment system (optional), independent R9 function (optional), manual focus adjustment function (standard)

7. Base configuration: Germany imported balance arm system, light head is designed by Germany engineer, USA LED bulb, Taiwan power system

Product feature:

1. Lamp shell is ABS material, integrated design with four handles around and streamlined ultra-thin design, the thickness is not more than 18CM, obtain excellent effect of laminar flow

2. Use international advanced warm white LED as shadowless illuminant, environmental, lower energy consumption LED bulb, bulb life: 60000 hours

3. LED do not engender infrared ray and ultraviolet radiation, it doesn't have the temperature rise and tissue damage caused by halogen shadowless light, can accelerate the wound healing after surgery, and has no Radiation pollution

4. LED color temperature is constant, soft and not dazzling, close to natural light

5. The main light use 128LEDS(main bulb)+384LEDS(spare bulb) independent LED illuminant (lamp cup is one main and three spare bulb structure), divided into multiple independent illuminant group, subsidiary light use 56LEDS(main bulb)+168LEDS(spare bulb) LED illuminant (lamp cup is one main and three spare bulb structure), divided into multiple independent illuminant group; every lamp use double CPU control, every group of LED illuminant controlled by special circuit chip, any group failure will not affect the normal use of shadowless light.

6. Double switch control system, when control panel failure, emergency switch which installed on light head can be used, guarantee light normal work. Control panel in the spring arm joint, film touch switch, easy to use, Not easy to damage

7. Microcomputer digital control, illumination can be adjustable; stepless adjustment, eight segments continuous indicating, adjustment range: 10%-100%, backlight illumination: 30 Lux; it offers illuminance memory function

8. Adopt restrain interference design of electromagnetic wave, avoid disturb with the other equipment in operating room

9. Use satlite oval swing pipe design, can install 4 cantilever devices in complex operating room, also can be reserved per hospital's request, convenient to upgrade and provide perfect solution for the increasing multi-media request of hospital

10. Balanced system using imported German Ondal arm module, more than 5 group universal joints, every cantilever must has more than 3 joints which can be rotated in 360 celsius degree, equipped with fatigue correcting unit and fix position hand handle device, easy to fix position after using for long time

11. The handle on the central of lamp can be detachable, can take high temperature (134 celsius degree) sterilization treatment, easily adjust, flexible fixed; Adopt balanced arm, handy operate, and make sure the lamp stable during operation; has C-arm joint control panel, has luminance prompt facility, provide environment lighting models

12. Lamp panel radius of gyration: 182cm, the lamp can be pulled to vertical floor, convenient to any angle illumination. Unify ABS operate handle and mid-operation handle of Lamp rim convenient to operate. Product execute international IEC standard.
