Humidifier Inspection Standards,Does it really work?
1. Purpose(Humidifier Inspection Standards)
In order to clarify the company’s humidification, sprayer products finished product inspection norms and standards, for the production of suppliers, to provide a basis for determination, the development of this standard.
2. Scope of application(Humidifier Inspection Standards)
Applicable to the company’s JR-CY337/338 humidifier products finished product inspection.
3. Defect definition:
3.1 serious defects (CR): the user’s life is a major hazard or has the potential to harm and violate the relevant safety requirements of defects
3.2 major defects (MA): affect the use of the product, reduce product reliability and service life or seriously affect the product image defects
3.3 Minor defects ((MI): the product has a slight appearance defects and does not affect the product function defects
4. The level of inspection:
4.1 Sampling standards: MIL-STD-105E
4.2 Acceptance level (AQL): CR=O MA=0.65MI=1.0
5. Inspection items and technical requirements are as follows
- Package
- Appearance
- Function
Package
packing box (inside and outside) cushioning materials (upper and lower foam cushion), packing plastic bag (CPE) should be complete, no use of error.
Packing the correct way, good packaging, no obvious dirty, broken, deformation. and other undesirable phenomena.
Attachments should be complete, no misuse, placed in the correct way.
The printed content is consistent with the document and error-free
No obvious soiling, breakage, deformation.
Do one corner, three sides and six sides drop test as required.
Appearance
Surface should be smooth, uniform color, no obvious cracks, spots, scratches and dents. The surface etching pattern meets the requirements. Plastic parts without miscellaneous colors, flying edges, shrinkage marks, fusion marks and obvious injection dissatisfaction and other undesirable phenomena.
The surface of the screen printing parts screen printing pattern text correct, no blurred phenomenon, screen printing firm, can pass the wet cloth wipe test and adhesive paper tear off test.
Spraying parts surface shall not have obvious scratches, spraying oil layer flaking, wrinkles; surface should be uniform color, smooth, firm coating.
No obvious dirt, scratches, no burrs, deformation. Oxidation parts surface oxidation layer should be good, shall not appear to drop the transition layer and other issues
The color of each appearance parts meets the specified requirements, and the color matching of the whole machine meets the specified requirements; there is no obvious color difference between the same batch of products.
Function
Product input voltage such as DC5V; connected to DC power supply, the indicator is consistent with the sample
The keys and touch feel good, the function is normal: no delay in switching on and off, the indicator is normal.
No key operation, no card key, collapse, insensitive, no response to the key, press
Key function does not match the bad, key hand sensing and sample consistent; test each key function in turn
Test each key function in turn, test the corresponding mode change, toggle switch each gear level, toggle smoothly: (Note that the test point should follow the side of the key.
(Note that the test points should follow the key corners and central selection points)
Operation in accordance with the specifications, no indicator light does not light, indicator color, mode error and other bad: operation of each gear in turn, against the instructions to show the mode, color, etc. need to meet the requirements of the specifications.
Functional test after combination with each accessory: normal operation without noise; assemble each accessory in turn, turn on the humidification, no abnormal function.
35cm away from the product at the power-on test, the maximum value of each gear noise can not be greater than the specification value, and the sound is soft and not harsh; (background noise is less than 20dB) W45dB
Operating hours in accordance with the requirements of the specifications: the battery is fully charged, after loading water test humidifier each
Gear load operating hours. (without not measured)
30 cubic meters of room, 25-30 ° C, humidity below 40WRH, the humidifier will be placed in the d-room, from the ground and 0. 5-lm high, the water tank is filled with water, to the maximum humidification run lh after weighing the total weight of the water tank A, and then continue to run 5H, shut down, at this time weighing the weight of the water tank B, this formula to calculate the atomization volume: (A-B) /5, that is, the average atomization volume of the machine (ml / h) o not less than or more than 30%.
- Fog appears within 3-5 seconds of power on, uniform atomization, no fog intermittent phenomenon, no water droplets sprayed from the fog outlet.
- When working, the fog outlet shall not have large water droplets formed, the fog outlet shall not be sealed by water droplets, there shall be no water droplets from the fog outlet outflow and other phenomena.
The whole machine to the maximum humidification capacity for normal work, 5 minutes after the power on immediately observe the whole machine
Fog situation, in addition to the fog mouth, the rest of the machine anywhere should not be fog leakage.
Refer to the definition given in the company’s specification and whether the sample is consistent.
Refer to the definition given in the company’s specification and whether the sample is consistent.
The whole machine works normally, when the water level gradually decreases and is in the water shortage state, observe the water shortage indicator condition. At this time the machine should stop working, while the water shortage indicator light is on. (without not measuring)
Tighten each part of the water tank, apply 3kg of air pressure at the water tank outlet, immerse the water tank bonding surface and each sealing surface into the water, keep 5s, observe each part of the situation should be no leakage.
Transparent and bright water tank, no obvious black spots or pulling the phenomenon, the bonding place no obvious bonding
Agent leakage should meet the requirements.
No obvious scratches, cracks or rust on the surface of the atomization sheet transducer should meet the requirements.
Check whether the power is in accordance with the product specification
Continuous use 2H, continuous charging 1H (no abnormalities in basic functions after aging), please ask the factory to do aging in advance (at least 5pcs)
Humidifier performance before and after the experiment should be no significant differences, humidifier rated voltage operation, full blocking suction 10s, and then full open suction 10s, as a cycle, a total of 10 cycles after the test humidifier performance. (No fog)
Manually press the button 100 times, no feel bad, no function failure
Use 3, 1600# (or 610#) adhesive paper in the screen printing position after 90 ± 30 seconds after 90 degrees fast pull 3 times continuously screen printing should not fall off. Use gauze with 95% or more concentration of anhydrous alcohol, plus 500g/cm2, at a speed of 40-60 times / min, 20mm stroke back and forth 10 times, back and forth count once, check whether there is bad.
According to the product function specification, the product should meet the requirements.
Drop height 70cm; drop front and back side (key side is front side), test 1 round; drop to the ground.
The function must not fail, and the appearance is allowed to have slight scratches, scrapes and damages, but must not have cracks.
