4
Update on previous recommendations

• Feedback on implementation
• 12 month calibration certificate validity period
• Reduce minimum lot size to 1,500 litres for
  assessing spray rates
• Update Sabita Manual 8 on safe handling of
  binders to incorporate Austroads experience
• Modify bakkie test method to incorporate
  tolerance limits for adjacent bakkies

Way forward

• Publishing of recommendations
• Bakkie test method on CSIR website
• Drafting interim guideline (TG 3) to incorporate
  recommendations until COLTO reactivated
• Develop computer programme to correlate fix pit
  transverse distribution with Bakkie test

• Develop on-site carpet test for high profile
  
• projects
• Develop a new frame work for Distributor
• Calibration
