The Weighing Equipment (Automatic Gravimetric Filling Instruments) Regulations (Northern Ireland) 2005 No. 27

SCHEDULE 4 (Descriptive markings and verification markings: Extract from Part 1 of OIML R 61 and additional marking)

Markings shown in code

• 3.10.2.  pattern approval sign

• indication of the accuracy class X(x)

• reference value for accuracy class Ref(x)

• scale interval (if applicable) in the form: d= ... ... ... ...

• maximum capacity in the form: Max= ... ... ... ...

• minimum capacity (or minimum discharge where applicable) in the form: Min= ... ... ... ...

• maximum additive tare in the form: T=+ ... ... ... ...

• maximum subtractive tare in the form: T=− ... ... ... ...

An instrument may be verified for different materials for which different classes apply or which require different operating parameters to maintain limits of error. Marking shall be such that the alternative class or operating parameters are clearly associated with the appropriate material designation.

In the case of subtractive weighers the minimum load to be discharged shall be specified.
