BS ISO 6361-3:2014 pdf download.Wrought aluminium and aluminium alloys – Sheets, strips and plates Part 3: Strips: Tolerances on shape and dimensions.
This part of Iso 6361 specifies the tolerances on shape and dimensions for wrought aluminium and aluminium alloy strip by cold-rolling for general engineering applications.
It applies to products with thickness of over 0,15 mm up to, and including 16 mm.
It does not apply to semi-finished rolled products in coiled form to be subjected to further rolling (reroll stock), or to special products such as those that are corrugated or embossed.
Technical conditions for inspection and delivery of products covered by this part of ISO 6361 are specified in ISO 6361-1.
2 Dimensional tolerances
2.1 Thickness
Thickness tolerances shall be in accordance with Tables 1 and 2.
When the tolerance is specified as either all plus, or minus side, the value in Table 1. or in Tabk2, shall be doubled.
Tolerances for the products exceeding the range of specified thickness and width shall be agreed upon by the purchaser and the supplier.
2.2 Width
Width tolerances shall be in accordance with Table 3.
When the tolerance is specified as either all plus, or minus side, the value in Table 3 shall be doubled.
Tolerances for the products exceeding the range of specified thickness and width shall be agreed upon by the purchaser and the supplier.
3 Shape tolerances
The lateral curvature is the depth of the are for any 2 000 mm basis lengths (see Figure 1).BS ISO 6361-3 pdf download.
