Standard Test Methods for Heat-Shrinkable Tubing for Electrical Use
These test methods cover the testing of heat-shrinkable tubing used for electrical insulation. Materials used include poly(vinyl chloride), polyolefins, fluorocarbon polymers, silicone rubber, and other plastic or elastomeric compounds.
The values stated in inch-pound units are the standard except for temperature, which shall be expressed in degrees Celsius. Values stated in parentheses are for information only.

Amendments: All current amendments are included with the purchase of this document.
Describes general requirements for classifying and testing of rosin, resin, organic and inorganic fluxes for high quality interconnections. This standard is a flux characterization, quality control and procurement document for solder flux and flux-containing materials of all compositions, including no-clean. Supersedes QQ-S-571 and MIL-F-14256. Co-produced with EIA. Amendment released April 1996.
An outer protective sheath over primary insulation, braids, shields, cable components, or over the cable itself. In fiber optics, a jacket is a covering over a single fiber, bundle of fibers or cable, which protects against the environment.
Joint industry standard Requirements for Electronic Grade Solder Alloys and Fluxed and Non-Fluxed Solid Solders for Electronic Soldering Applications.
Solder alloy quality (purity) is critical to successful soldering. Excessive impurities in a solder alloy will negatively affect solder joint formation, and ultimately solder joint quality and reliability. J-STD-006 Requirements for Electronic Grade Solder Alloys and Fluxed and Non-Fluxed Solid Solders for Electronic Soldering Applications is an important quality control document that describes requirements and test methods for electronic grade solder alloys. J-STD-006 is one of three documents related to soldering materials, the other two documents are J-STD-004 Requirements for Soldering Fluxes and J-STD-005 Requirements for Soldering Pastes
