ISO 14405-1-16-2016 pdf free download.Geometrical product specifications (GPS) – Dimensional tolerancing – Part 1: Linear sizes.
This part of Iso 14405 defines tolerances of linear sizes for the following:
— a + and/or — limit deviation (e.g. 0/—0,0 19) (see Figure 11)
— an upper limit of size (ULS) and/or lower limit of size (LLS) (e.g. 15,2 max., 12 mm., or 30,2/30,181) (see Figure 13)
— an ISO tolerance class code in accordance with ISO 286-1 (e.g. 10 h6) (see Figure 12)
with or without modifiers (see Tables 1 and 2).
This part of ISO 14405 provides a set of tools to express several types of size characteristic. It does not present any information on the relationship between a function or a use and a size characteristic.
