Acceptance Method Reference
1. Appearance
Test environment: 100W cool white fluorescent lamp, the light source is 50~55cm away from the surface of the object to be tested (illumination reaches 500~550LUX). The distance between the surface of the object to be tested and the eye: 30~35cm. The angle between the line of sight and the surface of the object to be tested: 45 ±15 ° Inspection time: ≤12 S. The inspectors have unaided or corrected visual acuity above 1.0 and no color blindness.
Dimensions: Measure the sample with a ruler or a vernier caliper with a precision of 0.02mm and record the value.
Weight: Use an electronic scale with a division value of 0.01g to weigh the sample and record the value.
Capacity: weigh the sample on an electronic scale with a graduation value of 0.01g, remove the gross weight of the bottle, pour tap water into the sample bottle to the full mouth and record the volume conversion value (if necessary, directly inject the paste or mix the density of water and paste conversion).
2. Sealing Measurement
Fill the container (such as a bottle) with 3/4 colored water (60-80% colored water); then match the pump , sealing plug, sealing cap and other related accessories, and tighten the pump or sealing cap according to the standard; Place the sample sideways and upside down in the tray (a white paper is placed in the tray in advance) and put it into the vacuum drying oven; lock the isolation door of the airless drying oven, start the airless drying oven, and airless to -0.06Mpa for 5 minutes; Then close the airless drying oven, open the isolation door of the airless drying oven; take out the sample, observe whether there is water stain on the white paper of the tray and the surface of the sample; then take the sample out and place it on the test bench, and gently tap the pump /seal Cover it a few times; wait for 5 seconds and unscrew it slowly (to prevent the color water from being taken out when the pump /seal cap is unscrewed, resulting in misjudgment), and observe the colorless water outside the sealing area of the sample.
Special requirements: If the customer requires a airless leak test under a certain high temperature condition, it is only necessary to set the temperature of the airless drying oven to meet this condition, and operate according to steps 4.1 to 4.5. {In addition, when the airless leak test negative pressure condition (negative pressure value/holding time) is inconsistent with the customer, please conduct the test according to the airless leak test negative pressure condition finally confirmed with the customer}
Visually check that there is colorless water outside the sealing area of the sample, and the colorless water is qualified. Visually check that there is colorless water outside the sealing area of the sample, and colored water is unqualified. If the color water outside the sealing area of the piston in the container exceeds the second sealing area (the lower edge of the piston), it is unqualified, and if it exceeds the first sealing area (the upper edge of the piston), the color water area will be judged according to the degree.
