Questions and Answers

What is the purpose of using a UKAS accredited laboratory for geotechnical tests?

  • To speed up the testing process
  • To ensure the accuracy and reliability of the test results (correct)
  • To bypass the need for ISO 17025 audit
  • To save money on laboratory testing

    • Why is it essential to use MCERTS accredited laboratories for chemical testing on soils for EA consideration?

  • To reduce the cost of chemical testing
  • To comply with regulatory requirements for environmental assessment (correct)
  • To simplify the documentation process
  • To avoid auditing against ISO 17025

    • What is the consequence of not considering the sample mass at the sampling stage?

  • The accuracy of test results will be compromised
  • The laboratory will refuse to test the samples
  • The testing process will take longer than expected
  • Some tests will be impossible to conduct (correct)
