Industry Standard for Crimping Tools

IEEE Standards

• IEEE standards define proper termination of coaxial cable. According to "Network Cabling Illuminated" by Robert Shimonski, Richard Steiner and Sean Sheedy, "crimping tools, new style compression tools and other special tools specifically designed to assist in pushing the standard F-type connector onto the cable can be used." Grounding connections can be created by welding the sections or using mechanical pressure using a crimping tool. According to "Practical Grounding, Bonding, Shielding and Surge Protection," "temperature limits are stated in standards such as IEEE 80 and IEEE 837 for different types of joints." IEEE Standard 837 is used in qualifying permanent connections used in substation grounding. IEEE 837 is shared by the American National Standards Institute.

ASTM F1807

• ASTM F1807 is the Standard Specification for Metal Insert Fittings Utilizing a Copper Crimp Ring. The crimp ring is used for SDR9 cross-linked polyethylene (PEX) and raised temperature (PE-RT) tubing. This type of tubing is used in hot and cold water distribution systems. This standard requires that insert fittings are used along with the copper crimp ring to cut the polyethylene tubing. This standard applies to tubing from 3/8 of an inch to 2 inches in diameter.

Additional ASTM Crimping Standards

• Residential plumbing standards for use of crimping tools to seal plastic pipes initially called for both aluminum and copper crimp rings. The correct method of their use and verification of correct installation was developed by the ASTM. "Plastics Failure" by John Moalli states "these systems, as well as the constituents, eventually became covered by ASTM standards such as D3309 and F845." After the crimping tool is used and the pipes fitted together, ASTM standards also define how the connection is tested. ASTM F877 is used to test cross-linked polyethylene tubing connections. ASTM F2769 is used with cross-linked polyethylene raised temperature (PE-RT) tubing

Military Specifications

• The United States military issues specifications called mil-spec. Mil-spec standards exist for crimping tools based on both the type and size of the wire to be crimped. These standards are included in the Department of Defense Index of Specifications in family MIL-C-22520. Individual military specifications are further identified by a dash followed by a number and letter. MIL-C-22520/10D is used for crimping tools used on large coaxial shielded contacts. MIL-C-22507B is used for wire barrels sizes 16, 20 and 22. MIL-C-2250/2C is used for wire barrel sizes 20 through 28.
