استارداد آزمایش اندازه گیری مقدار کربنات خاک (شیمی خاک) ASTM D 4373 به فرمت PDF در 5 صفحه جهت دانلود قرار داده شده است.
Designation: D 4373 – 02
Standard Test Method for Rapid Determination of Carbonate Content of Soils
SCOPE
This test method covers the determination of carbonate content of soils and soft rock which can be readily broken down by mechanical effort. It is a gasometric method that utilizes a simple portable apparatus. Results should be clearly stated as the calcite equivalent in percent because different carbonate species cover a wide range of percent calcite equivalent as shown below for a number of carbonates
