NOTE Although material symbol designations
35、used in this standard might be the same as those in other standards using the designation system given in ISO 1190-1, the detailed composition requirements are not necessarily the same. 4.1.3 Number The material number designation is in accordance with the system given in EN 1412. 4.2 Material condi
36、tion For the purposes of this standard, the following designations, which are in accordance with the system given in EN 1173, apply for the material condition: R Material condition designated by the minimum value of tensile strength requirement for the product with mandatory tensile strength and elo
37、ngation requirements; H Material condition designated by the minimum value of hardness requirement for the product with mandatory hardness requirements; G Material condition designated by the mid-range value of grain size requirement for the product with mandatory grain size and hardness requirement
38、s. Exact conversion between material conditions designated R,H and G is not possible. Material condition is designated by only one of the above designations.Page 4 EN 1652:1997 BSI 1998 4.3 Product The product designation provides a standardized pattern of designation from which a rapid and unequivo
