4 Requirements
4.1 General
WARNING — Lead’s (Pb) toxicity is recognized, and its use has since been phased out of many applications. However, many countries still allow the sale of products that expose humans to lead. Lead is a neurotoxin (see Figure 1).
4.2 Material properties
Material properties shall be in accordance with Table 1.
The Brinell hardness is regarded as the test and acceptance value. All other indicated values are mean values and are regarded as typical values for the designer. In view of the range of possible alloy compositions, relatively large deviations from the indicated values must be expected in individual cases.
5 Designation
EXAMPLE Designation of a bearing metal having the symbol CuSn8P and a minimum Brinell hardness of 120:
