Turnaround times & Sample sizes:

 

Please note that if sampling is done by

the client that the correct sampling procedure

must be followed specified in the test method.

 

This is a list of Soillab tests and expected turnaround times and sample sizes.
The list is a work in progress and will be expanded in near future.
Days noted in the list refer to workdays with standard working hours.
Sample size refers to a single sample of the relevant test.

Please contact us if more detail is required.

 

Please note that reporting times may be influenced by factors like:

 

  • Weather conditions can influence sample preparation time

  • Certain test results consists of more than one type of test

  • Certain instances might require a re-test

  • A large workload: most laboratories work on a first-in-first-out basis, except if special arrangements are made

  • Public holidays and Pay-weekends

  • Unplanned strikes
