This section applies to field assembled glass curtain wall projects.
Quantity to be inspected: Each type of component shall not be less than 10% (minimum of 3 pieces), one of which is unqualified, double sampling, if there is still more than one unqualified, all shall be judged as unqualified, all shall be reworked, self-inspected, Only after passing the re-check can be installed.
After the installation of the curtain wall, randomly check the entire area of ​​a project in three places. If there is a non-conformity, double the sampling inspection, in which the non-conformity items are up to 20%, and all the items are returned for repair. After the inspection is completed, they can be delivered.

Excellent: consistent color, surface cleanliness, no pollution, no pits, pits, scratches, tight stitching, flat, horizontal and vertical, no wrong Taiwan dislocation. The allowable deviation between the installation of the connection curtain wall and the main structure in three directions is plus or minus 1 mm.
Glass Qualification: The glass is installed with the correct orientation, the surface is clean, smooth, warped, and free of contamination, reflecting no distortion in the external image. Four sides polished smooth, no gaps, no scratches on the film surface; no obvious color, appearance quality and performance in line with the current national standards.
Good: The glass is installed with the correct orientation, the surface is clean, flat, no warping, no pollution, the glass has the same color, and the film surface layer is in good condition, reflecting that the external image has no distortion. The four-sided 45-degree angle is smooth and smooth, and the lines cross the circle. The appearance is crystal clear. The appearance quality and performance are in compliance with the relevant national standards and regulations.
Beads and glass glue pass: Strips are straight, tightly sealed and securely mounted. The sealing strip is installed with tight sealing. The location where the sealing paste is used must be clean, and it should be firmly bonded to the sealed object. The appearance should be straight and there should be no obvious misalignment and smoothness. No stain outside the seam.
Excellent: The pinch pinch is straight, precise to the mouthpiece, it is firmly installed, it is uniform, the sealing bar is installed with tight impact, the part where the sealant is used must be clean, and it must be firmly bonded to the object to be sealed. The appearance is straight, and the error-free table is misaligned and smooth. , strict and beautiful. No stain outside the seam.
Inspection methods: observation, ruler check.
