MPQDS06 Dimension stone block pre-splitting Overview What is this standard about? This standard states the skills, knowledge and understanding required to demonstrate competence in splitting dimension stone using manual equipment, commonly referred to as delving or "plug and feather" splitting. You will be able to split the stone using plugs and feathers with either a hand or hydraulic hammer equipment and wedges to produce dimension stone products. Who is this standard for? This standard is applicable to operatives in the dimensional stone quarrying industry.
