Commencement Information

I1 Sch. 5 in operation at 8.5.2006, see reg. 1

Maximum permissible errors for class Y(y) instruments N.I.

(Principle from Clause 2.3 of OIML R51)

The maximum permissible error for any load equal to or greater than the minimum capacity (Min) and equal to or less than the maximum capacity (Max) in automatic operation shall be as specified in Table 1. (Note that the mpe-value includes the digital rounding error of the indicating device.)

Table 1

Load (m) expressed in verification scale intervals (e)		Maximum permissible error for class Y(y) instruments
Class Y(a)	Class Y(b)	Initial verification	In-service
0 <m ≤ 500	0 <m ≤50	±1.5 e	±2 e
500 <m ≤ 2,000	50 <m ≤ 200	±2 e	±3 e
2,000 <m ≤ 10,000	200 <m ≤ 1,000	±2.5 e	±4 e

(Principle from Clause 2.5.2 of OIML R51)

The maximum permissible error for any load equal to or greater than the minimum capacity (Min) and equal to or less than the maximum capacity (Max) for static weighing in non-automatic operation shall be as specified in Table 2.
