The material is designated either by symbol or by number (see Table 1 and Table 2).
4.1.2 SymbolThe material symbol designation is based on the designation system given in ISO 1190-1.
NOTE Although material symbol designations 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
