The designations of soil shall be determined in accordance with the current national standard “ Standard for Classification of Soil” GBJ 145. 1.0.4 The sorting out of soil test data shall be such that by means of assessing the soil mass unit characteristics and the law of their change based on the research on the samples (data measured during the tests), the results of soil tests will serve as accurate and reliable indexes of soil properties for the engineering design and construction. Analysis and sorting out of test results shall be conducted in accordance with Appendix A. 1.0.5 Instruments and equipment used in soil tests shall be in compliance with GB/T 1506 ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 50123-2019_English be delivered?Answer: Upon your order, we will start to translate GB/T 50123-2019_English as soon as possible, and keep you informed of the progress.
