1 Scope This standard specifies dimensional tolerance and machining allowance of die forgings of aluminium and aluminium alloy. This standard is applicable to die forgings of aluminium and aluminium alloy. 2 Dimensional Tolerance 2.1 Non die-spanning dimension and tolerance 2.1.1 Non die-spanning dimension refers to die forging structural dimension not spanning the die parting face and not influenced by the die underpressure amount; see dimension "L" as shown in Figure 1. ... ... ... ... 2.1.2 Non die-spanning dimensional tolerance shall be in accordance with those specified in Table 1. If Grade A in Table 1 is required, it shall be subjected to negotiation of the Supplier and the Demander and indicated in the die forging drawing and the order (or contract), otherwise, Grade B shall prevail.
