INTRODUCTION<br />
Barsplice Products, Inc. has conducted a series of tests on reinforcing bar mechanical lap splice sizes No. 4<br />
through No. 6. The tests have been conducted on black <strong>and</strong> epoxy coated Double Barrel Zap Screwlok <strong>®</strong><br />
Splices. The purpose of the testing is to ensure that products are manufactured to the quality st<strong>and</strong>ards of<br />
BPI's ISO 9001 Quality System <strong>and</strong> are capable of exceeding strength requirements of various Building<br />
Codes.<br />
TENSILE TEST PROCEDURE<br />
Test specimens were loaded monotonically in tension to failure to determine the capability of the splice<br />
<strong>system</strong>. The tests were conducted in accordance with "St<strong>and</strong>ard Test Methods <strong>and</strong> Definitions for<br />
Mechanical Testing of Steel Products", ASTM A370. The testing was performed to exceed the strength<br />
requirements of ACI (American Concrete Institute) 318, Section 12.14.3.2, namely 125% x specified yield<br />
strength of Grade 60 reinforcing bar.<br />
All monotonic tension tests were carried out in either a 600 kip Forney universal testing machine, located at<br />
the Barsplice Products, Inc. in-house laboratory or a 200 kip Satec universal testing machine, located at the<br />
A-Lab, Inc. independent laboratory. Current calibration certificates for the test machines are on file.<br />
TEST RESULTS<br />
Results of the tension testing are summarized in Table 1.<br />
The reinforcing steel used in these tests conforms to the requirements of ASTM A615, Grade 60.<br />
SUMMARY<br />
Tension test specimens exceeded the Type 1 strength requirements of ACI 318,<br />
Section 12.14.3.2, namely 125% x specified yield strength of Grade 60 rebar.<br />
