Size at the design of furniture size, the limits of deviation of size, at the beginning of the size and location of three kinds of tolerance:

Product design is the pattern size on the label size. Products such as high, wide and deep dimensions.

Main size, also known as the function of product size, is the product of a particular part of the design size, must comply with the provisions of this part of the standard size requirements. Standards such as the hanging wardrobe part of a requirement, deep clearance standards should be ≥ 530mm, the design must comply with the request size.

Deviation of the size limit refers to the product in kind, as measured by the measurement of product design, the size of the margin after. The limits of standard deviation of non-folding type ± 5mm, folding ± 6mm.

The shape and position tolerances Size: Warp points, smoothness, adjacent vertical edges, the potentiometer, the drawer swing, the down, the feet are the end products will not be Pingdu and joints, such as eight hours.

Warp refers to the products (components) on the surface of the extent of the overall formation. Standards require that the panel address the matter, if the diagonal length L <700mm, to allow the margin ≤ 1mm.

Flatness refers to products (parts) 0 ~ 150mm in the surface within the scope of the degree of partial formation. Roughness standard should be ≤ 0.2mm.

Adjacent vertical edge, is the products (components) for the rectangular shape at the moment the extent of not. Standards, measuring the two diagonal
Length L to allow the margin ≤ 2mm, the framework of the diagonal length L ≥ 1000mm, to allow the margin ≤ 3mm. <1000mm to allow the margin ≤ 2mm.

Potentiometer degrees refers to the door and frame products, door and gate, door and drawer, the drawer and frame, a drawer with the drawer next to the distance between the two surfaces. Standard door and frame, door and folding door distance between adjacent surface deviation (the distance between the non-design requirements) to allow ≤ 2mm, and the framework of the drawer, the drawer and door, two drawers and a drawer next to the distance between the surface deviation (non-design requirements distance) allows ≤ 1mm.

Drawer swing, the down, the framework refers to the co-ordination of the drawer with precision. Standard depth of the drawers pulled out of the 2 / 3, the swing degree should be ≤ 15mm, drooping degree should be ≤ 20mm.

Products at the end of the foot to the roughness, is the product of the ground at the end of the foot of the smooth. Roughness standard should be ≤ 2mm.

       Sub-crack is the product of external components and the headstock with the gap between the framework, said sub-joints. The largest sub-standard joints shall not exceed 2mm and 1.5mm.
