Smoke Density

This standardized test method used to determine the specific optical density of smoke emitted by solid materials and assemblies during exposure to a controlled radiant heat source. The test maybe conducted in both flaming and non-flaming modes to comprehensively assess the smoke generation characteristics of materials. In the flaming mode, the material is subjected to […] Read more

Shield Strand Coating

The shield plating of cables is performed in a similar manner as is performed for wire conductors. Typically, this involves exposing the shielding to one or more chemicals to see if there is a reaction of the underlying copper conductor. For the NEMA27500 cables, this method is applicable to tin, silver, and nickel. Read more

Plating Thickness

The conductor plating thickness may be determined through several methods called out in the EN3475 test method. These include: Optical Chemical Scanning Electron Microscope (SEM) Atom Absorption Spectrometry (AAS) When contacting Lectromec about this test, please identify if there is a preferred method for your application.

Cable and Leadwire Noise

Piezoelectricity refers to the phenomenon where certain materials generate an electric charge when subjected to mechanical stress or pressure. Conducting a piezoelectricity test on a data cable involves evaluating whether the cable exhibits any piezoelectric properties under specific conditions.  General Test Procedure Assess the voltage differential on the cable prior to mechanical stress.  Apply a […] Read more

Cable Twist-Bend – Fiber Optic Cable

The fiber optic cable twist-bend test is a procedure performed to assess the mechanical reliability and performance of fiber optic cables when subjected to twisting and bending forces simultaneously. It aims to evaluate the cable's ability to maintain signal integrity and durability in scenarios where it experiences combined twisting and bending stresses. During the twist-bend […] Read more

Crush Resistance – Fiber Optic Cable

Fiber optic cable crush testing is a procedure used to evaluate the resistance of fiber optic cables to crushing forces or pressure. It aims to determine the cable's ability to withstand external pressure without experiencing significant deformation, signal loss, or damage to the fiber. During crush testing, the fiber optic cable is subjected to controlled […] Read more

Kink Testing – Fiber Optic Cable

Fiber optic kink testing is a procedure used to evaluate the flexibility and resistance of fiber optic cables when subjected to bending or kinking.
