Answer :
Final answer:
The standard penetration test is falsely referred to as ASTM D 1569; the correct standard is ASTM D1586, whereas ASTM D698 relates to laboratory soil compaction characteristics. B. False.
Explanation:
The statement that the standard penetration test is referred to as ASTM D 1569 is False. The standard penetration test (SPT) is actually denoted by ASTM D1586, which describes the test method used to measure the resistance of soil to penetration. This test is a common in-situ testing method used to estimate the geotechnical engineering properties of subsurface soils. The Standard Penetration Test is referred to as ASTM D 1586, not ASTM D 1569. This test is commonly used in geotechnical engineering to determine soil properties. ASTM D698, on the other hand, refers to the Standard Test Methods for Laboratory Compaction Characteristics of Soil Using Standard Effort. Different ASTM designations correspond to different procedures and standards in soil and rock testing and should not be confused with each other.
