4、ination of hydraulic proper-ties.This guide does not establish a fixed procedure fordetermination of hydrologic properties.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 LimitationsWell techniques have limitations in the
5、determination of hydraulic properties of groundwater flowsystems.These limitations are related primarily to the simpli-fying assumptions that are implicit in each test method.Theresponse of an aquifer system to stress is not unique;therefore,the system must be known sufficiently to select the proper
6、analytical method.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.
