Astm D4945 89 Pdf Download

If you are looking for a standard test method for high-strain dynamic testing of deep foundations, you may be interested in downloading the Astm D4945 89 Pdf document. This document, published by the American Society for Testing and Materials (ASTM), describes the procedure for applying an axial impact force with a pile driving hammer or a large drop weight that will cause a relatively high strain at the top of an individual vertical or inclined deep foundation unit, and for measuring the subsequent force and velocity response of that deep foundation unit. High-strain dynamic testing applies to any deep foundation unit, also referred to herein as a pile, which functions in a manner similar to a driven pile or a cast-in-place pile regardless of the method of installation, and which conforms with the requirements of this test method.


The Astm D4945 89 Pdf document was first issued in 1989 and has been revised several times since then. The latest edition is Astm D4945 17, which was approved in 2017. However, some engineers and contractors may still prefer to use the older version of the standard for various reasons, such as compatibility with existing equipment, familiarity with the procedures, or contractual obligations. Therefore, it may be useful to have access to the Astm D4945 89 Pdf document for reference or comparison purposes.

Unfortunately, the Astm D4945 89 Pdf document is not readily available online for free download. The ASTM website only provides access to the most recent edition of the standard, which requires a subscription or a payment to view or download. Some other websites may claim to offer the Astm D4945 89 Pdf document for free download, but they may be unreliable, unsecure, or illegal. Therefore, it is advisable to exercise caution and discretion when searching for the Astm D4945 89 Pdf document online.

One possible way to obtain the Astm D4945 89 Pdf document is to contact the ASTM customer service at and request a copy of the document. You may need to provide some information about your identity, affiliation, and purpose of use. You may also need to pay a fee for the document delivery. Alternatively, you may try to find a library or an institution that has a subscription to the ASTM standards and ask for permission to access or borrow the document. You may also try to contact some colleagues or peers who have previously used or purchased the document and ask for their assistance or advice.

In conclusion, the Astm D4945 89 Pdf document is a valuable resource for engineers and contractors who are involved in high-strain dynamic testing of deep foundations. However, it is not easy to find or download online for free. Therefore, you may need to explore some options and take some precautions to obtain the document legally and safely.
