Kuidas katusekontrolli läbi viia?

Vihmavari koosneb tavaliselt vihmavarju kattest, vihmavarju võll, vihmavarju käepide, ja vihmavarju. Vihmavarju detailide detailid on jooniseks.

But how should we perform an umbrella inspection?

Esiteks, peaksime kontrollima selle suurust. Suuruse mõõtmise kontroll sisaldab vihmavarju läbimõõtu, vihmavarju ja ribi kogupikkus. Kontrollige rohkem suurusi, kui spetsifikatsioonil on täpsed nõuded. Tavaliselt tolerants on +/-1 cm, kui see pole spetsifikatsioonis täpsustatud.

Teiseks, you need to test the run performance of the umbrella. I usually open and close a tested samples 10 times, to check if it runs all smoothly. I usually test 1% of the total quantity at the minimum of 3 tükid. But you can always require the tested sample quantity.

Then I do the visual inspection for make and workmanship.

The checklist of umbrella inspection includes:

1. Cleanliness

If there is soiled panel or rust spots on fabric or on metal

2. Material issues

If there is holes or cut on fabric, or weaving defects on fabric, or any kind of printing fault.

3. Accessories defects

Any accessory problem could be a major defect on umbrella, however you need to evaluate it how bad it affects the function of product

4. Mechanism problem

If the mechanism works too easy or too stiff

5. Sewing defects on umbrella cover

You need to inspect all stitchings on umbrella cover and all seams to see if there is missing stitching, broken stitching, loose stitching, run off stitching, open seam and whatever.

6. Any other defects, packaging issues, labeling issues
