ASTM D4935: Standard Test Method for Measuring the Electromagnetic Shielding Effectiveness of Planar Materials

This test method provides a procedure for measuring the electromagnetic (EM) shielding effectiveness (SE) of a material due to a plane-wave, far-field EM wave. The test utilizes a coaxial transmission line to determine the shielding effectiveness of a given material. The test method is valid for a frequency range of 30 MHz to 1.5 GHz. Various thicknesses and types of materials can be tested to acquire a relative ranking of shielding effectiveness.

RTP 600 Series
Acrylonitrile Butadiene Styrene
Compounds

Advantages
• Dimensional stability
• Toughness - even at low temperatures
• Chemical resistance

Limitations
• Weatherability
• Solvent resistance
• Smoke generation when burned

The ABS three monomer system can be tailored to yield a good balance of properties. Basically, styrene contributes ease of processing characteristics, acrylonitrile imparts chemical resistance and increased surface hardness, and the butadiene contributes impact strength and overall toughness. ABS is considered the best of the styrenic family. It is hard, tough and rigid.

ABS is severely attacked by some solvents. Prolonged exposure to aromatic solvents, ketones and esters should be avoided. This poor resistance to solvents does allow solvent bonding as a means of assembly.
