4 types of bars in sizes 100, 200 and 300 mm and 3 types of tables inclinable about a single axis in sizes 100, 200, 300 and 500 mm. Precision tolerances on all functional elements and requirements for those features of design and manufacture which affect performance.

This British Standard specifies requirements for metric sine bars and sine tables, excluding compound tables.

Section 2 provides for four types of sine bar, illustrated in Figure 1, made in sizes of 100 mm, 200 mm and 300 mm.

NOTE Bars of 50 mm width and over are often referred to as sine plates.

Section 3 provides for sine tables inclinable about a single axis in sizes of 100 mm, 200 mm, 300 mm and 500 mm.
