MLS UNIMATIC® Blind Rivets (NAS1900 Series) : MIL-HDBK-5 Data

MIL-HDBK-5 Data

As part of the industry acceptance procedure it becomes necessary to perform static lap shear tests to the requirements outlined in chapter 9 of MIL-HDBK-5. With the approval of the test results the established yields and ultimate performance data in varied sheet material thickness is published in MIL-HDBK-5 chapter 8. The published values give aerospace designers the joint strength information needed in design of structure. Generally if a product does not have MIL-HDBK-5 performance data the product is overlooked for design.
The MLS blind rivets in all materials were tested and approved for publication in the mid 1970’s and data was published under the NAS parts standards number.

(1) a Indicates shear strength is documented in NAS1900
(2) b indicates yield is less than 2/3 of the indicated ultimate strength value
(3)The bold line indicates knife-edge
(4) Yield strength as shown was established with a permanent set of .04% offset. These   tables were reworked in 1985 to the current offset from the original tables that used a different offset.
