NZS 3104:2003 Specification for concrete production sets the minimum requirements for the production of fresh concrete, and was last amended in 2010 (Amdt 2) to incorporate more than one type of mechanism used for weigh systems.

The much-needed revision of NZS 3104 will update the Standard to align with current practice and allow for better control of the manufacture of concrete.

This revision of NZS 3104:2003 Specification for concrete production will reflect current recognised practice and will:

  • allow an alternative method to calculate target mean concrete compressive strength based on normal distribution theory in clause 2.13,
  • update other clauses throughout the standard relating to the introduction of the alternative method; and
  • clarify and update clauses throughout the standard to reflect current practice and technology.

The draft is available for public comment for a period of 8 weeks. All comments submitted during this period are reviewed by the Standards Development Committee before the standard is balloted on.

The closing date for comments is 21 June 2020.

Copies of the draft Standard can be downloaded from the Standards NZ website along with a submission form.
