Installing a long-cherished chandelier can instantly transform the atmosphere of a new home into a warm and elegant one. So, how are these exquisite chandeliers quality-tested? What does the inspection standard cover?

1. Packaging inspection <br>The packaging labels must be correct and clear, and the outer box should be free of damage, indentations, and cracks. The correct type of paper packaging material must be selected to ensure that it can pass the transportation drop test. The printed content of the outer box (including front mark, side mark, order number, net weight, gross weight, machine model, material, box number, product diagram, place of origin, company name and address, as well as fragile, moisture-proof, and direction markings, etc.) should be accurate, and the printed color must meet the color plate requirements. The entire batch of colors must be consistent without significant color difference, and the handwriting and patterns must be clear without ghosting. The outer box size error should be controlled within ±1/4 inch, the crimping line should be accurate, and there should be no loosening. The computer barcode should be clear and scannable.

2. Appearance Inspection

1. Electroplating parts :

   • The color must be uniform, with no obvious color difference from the sample;

   • The surface must be free of scratches, sand, acid spitting, sand marks, pinholes, pitting, blistering, peeling, whitening, rust, black spots, paint flow or weld scars;

   • The brightness should be close to that of a mirror, without any white fog, and the hand feeling should be smooth and not rough;

   • The inner surface of the product must not be obviously blackened, dirty or oxidized;

   • There should be no scratches after wiping with white gloves;

   • Both adhesion and hardness tests must be passed.

2. Painted parts :

   • Compared with the sample, the overall color is consistent, with no obvious color difference or gloss difference;

   • There should be no paint leaks, paint peeling, sand, peeling, scratches, blisters or abrasions;

   • The paint surface should be even and smooth, without scars or paint flow, and the paint boundaries should be clear without overflow;

   • There is no rust on the inner surface, and the structure is not deformed or desoldering;

   • Adhesion and hardness tests must be qualified, and the hand-painted paint should have a layered feel.

3. Assembly and structural testing

• The error between the lamp body size and the design data shall not exceed ±1/2 inch, and all parts shall conform to the engineering parts list without missing parts;

• After assembly, the structure should be tight and not loose, and the whole structure should be visually at the same level without any skew;

• The gear points of the movable single chandelier must be effective;

• The lifting chain, load-bearing tube and other load-bearing parts must have sufficient load-bearing capacity;

• If the lamp weighs more than 5.5 kg, a crystal hanging ring must be used. Products exported to Europe must pass the ground wire continuity test.

4. Electrical safety test

• Grounding test : The plug must be grounded. Under the conditions of 10A current and 100mΩ resistance, the result must meet the standard within 3 seconds.

• High voltage test : The lamp body must be able to withstand high voltage test without leakage. The test voltage standard is: 2U + 1000V (U is the rated voltage of the country where the product is exported);

• Functional test : Perform power-on and lighting test. If a switch is included, the switch test must be repeated;

• Polarity test (for the US market): The lamp holder must be tested for polarity. Wrong or missing connection of positive and negative poles is strictly prohibited.
