salt-spray-test

Salt Spray / Cyclic Corrosion Testing Services

Salt spray testing and salt fog testing are corrosion test processes which subject coated or painted Medical, Telecom, IT, automotive, and military equipment in a controlled environment to expose susceptibility to material corrosion.
The cyclic corrosion testing, the material being tested is cycled through several different environmental cycles which include salt spray, temperature, humidity, or other variables determined by the test standards. A cyclic corrosion test is a testing process that more closely simulates real-world conditions where salt spray or salt fog is designed to create a caustic environment and allow the part to soak for a specific amount of time.

Salt Spray/ Cyclic Corrosion Tests Capabilities Include:

  • Temperature Range: From Room Ambient to +70°C.
  • Humidity Range: From Room Ambient to 95% RH.

Electrical Monitoring Capabilities

Along with Environmental and Vibration testing, Envitest Lab has a wide range of instruments to accurately gauge sample performance. These types of measurements are useful to verify sample conformance to applicable standards or for comparative analysis to determine if there is a change in sample performance following any environmental tests:

SIR (Surface Insulation Resistance) –
SIR is defined as the resistance that is generated when materials made for insulation are surrounded by grounding devices and electrical instruments within certain atmospheric conditions. SIR testing is done to determine whether a product or application is capable of withstanding failure due to leaking currents or short circuits in the Conditions of high humidity — preferably around 85°C/85% RH and 40°C/90%

ESS (Environmental Stress Screening) –
Environmental Stress screening is an essential step in the design cycle of electronic systems, particularly as these systems shrink in size and increase in complexity to satisfy the growing customer need for low-power, portable, high-quality gadgets. Maintaining a high operational reliability and offering fault-free operation in all types of operating environments require careful product design, during which you must keep several factors in view. ESS is a useful process that exposes product weaknesses and allows you to make corrections in the design. Faults you detect during in-house testing are less expensive to correct than equipment failures in the field.

LLCR (Low Level Contact Resistance) –
The resistance of a material falls into two categories: intrinsic and electrical, and contact resistance refers to the latter. Other terms used to describe this process include “transitional resistance” and “interface resistance.”

Voltage Drop – Explains how the provided energy within a source of voltage is trimmed as the electrical currents travel through things that don’t do not provide voltage to the circuit.

RLC (Resistance, Inductance and Capacitance) – An RLC electrical circuit is made up of a resistor, inductor and capacitor, which connect in tandem or sequence, but not necessarily in the order of the acronym. RLCs have numerous uses in terms of oscillation.

IR (Insulation Resistance) – Insulation resistance (IR) tests — alternately referred to as Meggers—use DC voltage to calculate the resistivity of insulation in kilohms, megohms, and gigohms.

DWV (Dielectric Withstand Voltage): AC/DC Hi-pot – This is an electrical test administered on products and parts to gauge the strength of insulation, which helps determine a product’s potential to run reliably under various conditions.

Sound Power and Sound Intensity Measurements

Sound Intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area.
Sound Power or acoustic power is the rate at which sound energy is emitted, reflected, transmitted or received, per unit time.
We at Envitest Laboratories now equipped with Sound Intensity measurements and sound power measurements as per ISO 9614-1, ISO 9614-2, ISO 3744, ISO 3745 and many more Acoustic standards. Envitest has also equipped itself for field data measurements and mobile data measurements for the given units.

Modal Analysis

Whenever any structure or chassis needs to be defined for the behaviour for operational, fatigue, reliability, Modal analysis come hands on. Modal analysis is the study of the dynamic properties of systems in the frequency domain where the dynamic response of structures other systems during excitation is analyses. We have packed ourselves to take up the test and analysis to provide the complete damping and dynamic properties. Our methods include creation of geometry, testing with either shaker or hammer, FRF, Mode parameters and Damping calculation in systematic way.
