NOTE 1 inspection, which have a different test method and a recommended test load of 6 kN.The trial static strength tests are not the same as the proof load tests carried out during a detailedNOTE 2 The strength of concrete in existing structures is rarely known but can generally be safely assumed to be greater than 30N/mm². Trial tests are therefore not needed in concrete structures if the type test was carried out in a sample of no more than 30N/mm². Trial tests may be justified if the condition of the concrete has deteriorated sufficiently to suggest its strength may be lower than that of the test sample.
