[China Aluminum Industry Network] 1. Factory inspection Each batch of products should be tested at the factory. Inspection items include: appearance quality, dimensional deviation, film thickness, gloss deviation, adhesion, acid resistance, mortar resistance, solvent resistance, sealing quality, impact resistance, and welding nail connection.

1.1 Batch inspection rules The delivery inspection shall consist of one inspection lot for the same type, the same color, the same production batch (continuous production) and the actual delivery volume of every 3000m2. When the delivery volume is less than 3000m2, it still counts as one inspection lot.

1.2 sampling methods a) Appearance quality, welding nail connection should be checked one by one;

b) Sampling of dimensional deviation, film thickness and gloss deviation inspection shall be carried out in accordance with Table 8;

c) Tests for adhesion, acid resistance, mortar resistance, solvent resistance, plugging quality, and impact resistance. Each lot is sampled for inspection. The destructive inspection items are prepared according to the requirements of the samples specified in Table 7 of this standard.

1.3 Judgment and re-inspection rules a) When one or more performances of the test result are unqualified, double-sampling shall be conducted from the batch for re-inspection. The results of the re-examination still have one or more performance failures of the sample. , then determine the batch is not qualified.

b) If the quality of appearance fails, it will be unqualified.

c) When the dimensional deviation, film thickness, gloss deviation test exceeds the upper limit of the nonconforming product specified in Table 8, the batch is judged as unqualified. However, the supplier is allowed to check block by block and the qualified person is delivered.

2. Type inspection 2.1 Under normal production conditions, type inspections shall be carried out at least once a year. The inspection items shall comply with all the requirements specified in Clause 6 except 6.6.2. When one of the following conditions is encountered, a type test should be performed:

a. Testing and finalizing of the production of new or old products to the factory;

b. After the formal production, if there are major changes in the structure, materials, and processes, the product performance may be affected;

c. The product is discontinued for more than half a year and resumed production;

d. Normal production is tested once a year, in which neutral salt spray resistance, accelerated aging resistance to man-age, and damp-heat resistance are checked once every two years.

e. When there is a big difference between the factory inspection result and the last type inspection.

2.2 Batch inspections The type inspection consists of one inspection lot of the same type, the same color, the same production batch (continuous production), and the actual delivery volume of every 3000m2. When the delivery volume is less than 3000m2, it still counts as 1 inspection lot.

2.3 Sampling Methods Sampling for performance testing is in accordance with 8.1.2.

2.4 Judgment and re-inspection The results of the type test of the type-rule test have one unqualified acid-resistance and mortar-resistance, and it is determined that the batch of products is unqualified. If one of the other items is unqualified, the unqualified product may be double-checked and rechecked. When the retest result meets the standard requirements, it is determined that the batch of products is qualified, otherwise, the batch of products is determined to be unqualified.

3. Marking, packaging, transportation, storage and accompanying documents 3.1 Markings For each packaging unit product, its packaging marking shall comply with GB/T 191 and GB/T 6388, and shall have the following markings:

a. company name;

b. product name;

c. product marking;

d. production lot number;

e. color and coating types;

f. aluminum brand;

g. Trademarks;

h. production date;

i. Directional requirements shall indicate the direction of production or installation;

j.

k. Quality inspection qualified mark.

3.2 Packaging 3.2.1 Products should be individually packaged. The decorative surface of each panel should be covered with protective film.

3.2.2 The packing box shall have sufficient strength to ensure that it will not be damaged during transportation, handling and stacking, and the product should not be shaken in the box.

3.3 There should be product certification and packing list within the packing box.

The certificate should have the following content:

a. company name;

b. production batch number;

c. test results;

d. Inspection department or personnel code;

e. Inspection date.

The packing list should have the following content:

a. company name;

b. product name, color, project name;

c. product marking;

d. production lot number;

e. the number of products;

f). Packing date.

3.4 Transport Transportation, transportation and handling should be handled with care, throwing and throwing are strictly prohibited to prevent product damage.

3.5 Storage Products should be stored in a dry and ventilated place to avoid high temperatures and exposure to the sun and rain. They should be stacked according to variety, size and color, and prevent surface damage.

3.6 accompanying documents accompanied documents should include: product certification, packing list and application guidelines.

Parking Lot Lighting

Parking lot lighting is the lighting equipment and program installed in the parking lot. Parking lot lighting is designed to provide enough light to ensure the safety of parking lot users and to ensure that they can clearly see vehicles, pedestrians and other obstacles.
