"Critical" fasteners made after July 26, 1998 must be tested by an accredited laboratory or produced by an approved manufacturing plant. The deadline represents a 60-day extension of previous delays in implementing the Fastener Quality Act (FQA) of 1990. The National Institute of Standards and Technology has required extra time to complete its approval of some 450 testing labs needed to carry out the act. FQA sets up a national program to ensure that certain nuts, bolts, and other fasteners used in "critical situations"--such as the attachment of aircraft engines to fuselages--conform to specifications. The government, meanwhile, also has defined the in-process quality inspection systems that fastener manufacturers can use to test their lots for FQA compliance. Operators of such lines can be provisionally certified, but they must complete official certification by May 25, 1999.
At the Design News webinar on June 27, learn all about aluminum extrusion: designing the right shape so it costs the least, is simplest to manufacture, and best fits the application's structural requirements.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
