Standards New Zealand has published Amendment 2 to NZS 3104:2003 Specification for Concrete Production.
Amendment 2 is the result of a project sponsored by the New Zealand Ready Mixed Concrete Association (NZRMCA) to incorporate a new type of mechanism for the testing of weigh-systems.
Since the initial drafting of NZS 3104, clauses dealing with weigh scale checking have remained unchanged. In this time there has been a significant introduction of load cell technology replacing the mechanical knife-edge systems that dominated in 1983.
Amendment 2:
- Recognises that there is now more than one type of mechanism used for weigh systems (knife edge/lever arm and load cell)
- Updates Clause 2.7.3 to take into account testing of weigh systems that are dependent on load cell mechanisms
- Corrects minor errors in the Contents
- Corrects Clauses 1.3, 2.9.1, and 3.1.4
