BS 1377-3:2018 PDF Download

BS 1377-3:2018 is a standard that provides methods for testing soils and ground water for chemical and electro-chemical properties that may have an impact on civil engineering purposes. This part of the standard specifically focuses on pH and electrical resistivity testing to evaluate aggressive ground conditions, corrosivity, and the potential for ground expansion.

The standard is intended for use by UKAS accredited laboratory managers, supervisors, and technicians, as well as civil and ground engineering contractors, consultants, clients, and other professionals involved in ground investigation and risk management. It offers a comprehensive and up-to-date set of test methods and best practice guidance for the UK industry, utilizing modern instrumental techniques commonly used in commercial testing laboratories.

BS 1377-3 provides a standardized approach to chemical testing, integrating modern analytical methods and serving as a single source for the methodology of chemical testing for civil engineering purposes. It expands the test types to cover weaker rocks, removes unreliable tests, and updates the methods used to analyze materials based on current practices.

The latest update of the standard introduces improvements in sampling and sample preparation for sulfur species testing, increases the number of chemical tests required by the industry, and removes an unreliable two-point electrical resistivity test. These changes aim to enhance the accuracy and reliability of the testing methods and align them with current industry standards.
