Should Polyimide Insulated Wire be Trusted?
The history of polyimide insulated wire is one that has numerous opinions and a lot of misconceptions. After several incidents involving polyimide wire on aircraft in both military and commercial, many within the aerospace industry refused to put any polyimide insulated wire/cable onto the aircraft they design/maintain. As is often the case with components involved in incidents, a lot of facts and myths get jumbled together. Read more
What is an EWIS Qualified Wire?
This is a question that Lectromec regularly receives. The reason for this question is that a parts-supplier or system-integrator is looking to find wires in compliance with EWIS requirements. Since there are so many ways to evaluate any component, the important question to consider is if a defined requirements list for aerospace wire exists? Here, […] Read more
Why use Lectromec for your Testing?
Not all testing is created equal. We have all seen the results of poorly performed tests – not only do they result in a waste of money, but also a waste of time – and when testing is delaying a product to market, the costs can be huge. Even with that in mind, it can […] Read more
Lectromec’s Testing Process
Testing can be complex. From test identification, locking down on test parameters, sample preparation, accurate test performance, proper data analysis, and delivery of a final report, an error anywhere in the process can cause costly delays and spurious results. Using the correct laboratory for testing is undoubtedly important. This article provides an overview of how […] Read more
AS4373 – Testing Aerospace Cables – Part 2
When is a wire good enough to be placed onto an aircraft? What environmental tests should be considered to clear it for flight? Are there ways to determine how easy it will be to handle for maintainers? Over the last couple of decades, a single test standard has evolved to with test methods to address […] Read more
AS4373 – Testing Aerospace Cables – Part 1
When testing aerospace wire, there are several test standards that might be considered; however, the one that is most commonly referenced is the SAE AS4373 “Test Methods for Insulated Electric Wire” which covers a wide range of mechanical, electrical, environmental, and workmanship tests. In this first article of a two part series, we describe the […] Read more
