FAQs

What is the test method for IEC 60068-2-52? ›

IEC 60068-2-52 – Methods 1-2

The duration of high humidity and number of cycle repeats is variable depending on the test method. One cycle consists of spraying samples with salt solution at 35 °C for 2h, followed by controlled humidity at 40 °C, 93% RH for six days and 22 h.

IEC 60068-2-52 salt mist testing, also known as salt spray testing or salt fog testing, is intended for application to components or equipment designed to withstand a salt-laden atmosphere, depending on the chosen severity.

The IEC 60068-2-64 package testing standard addresses structural integrity. The scope of this transit testing standard demonstrates the adequacy of equipment to resist dynamic loads under random vibration. Units that meet the test requirement have no or acceptable degradation of function or structural integrity.

Drop and topple: This IEC test is used to assess the effects of knocks or jolts likely to be received during repair work or rough handling. Free fall – Procedure 1: This test assesses the effects of falls likely to be experienced during rough handling.

EN 60068-2-2 Environmental Testing: Dry Heat

EN 60068-2-2 testing determines the ability of heat-dissipating and non-heat-dissipating specimens to withstand conditions of dry heat.

In this test, the specimen is exposed to the saline fog at the temperature of approx. 37°C. This is an accelerated test and helps in assessing the behaviour of the product in some hours. The test is usually performed for 24 hours, 48 hours, 72 hours or so on… or depending upon the internal standards.

The test mimics corrosive environments in an accelerated time frame, allowing you to compare the relative corrosion resistance of various coatings. In the test, the products are exposed to salt spray for 48 hours. Quickloader Hybrid products have been salt spray tested i.e products are corrosion resistant.

The salt spray test can give similarly misleading results when comparing different variants of zinc coatings. For example, small additions of magnesium or aluminium to a zinc coating will produce salt spray test results that differ significantly from real exposure conditions.

IEC 60068 is an international standard for the environmental testing of electrotechnical products that is published by the International Electrotechnical Commission (IEC).

What is IEC EN AS 60068 2 6 vibration? ›

IEC 60068-2-6: Sinusoidal Vibration Test Standard

It is applicable (but not limited) to products or components that are subjected to harmonic vibrations such as rotating, pulsating, or oscillating forces that occur in ships, aircraft, land vehicles, rotorcraft, machinery, space applications, and seismic events.

IEC 60068-2-78 Damp heat, steady state

IEC 60068-2-78 evaluates whether products or equipment can withstand transportation, storage and use under conditions of high temperature and humidity. The test conditions are high humidity at constant temperature without condensation on specimens over a prescribed period.

The goal of IEC-60068-2-1 cold testing is to determine the ability of components, equipment or other articles to be used, transported, or stored at low temperature. Cold tests covered by this standard do not enable the ability of specimens to withstand or operate during the temperature variations to be assessed.

IEC 60068-2-30:2005 Determines the suitability of components, equipment or other articles for use, transportation and storage under conditions of high humidity - combined with cyclic temperature changes and, in general, producing condensation on the surface of the specimen.

The IEC 60068-2-27 shock test covers components, equipment and other electrotechnical products, which, during transportation, storage, and handling, or in use, may be subjected either to conditions involving relatively infrequent nonrepetitive or repetitive shocks.

1.1 Thermal response test (TRT) The test is conducted by circulating a heated fluid (water or water + antifreeze) through the energy loop(s) enclosed inside a ground heat exchanger, generally a borehole having a length of at least 100 m [82].

Moisture Management Tester

A predetermined amount of a prepared test solution is dropped on the center of the upper facing surface (skin side) of the test specimen. As the solution is transported throughout the specimen, changes in electrical resistance are measured and recorded.

The ASTM C177 is the standard test for measuring a material's thermal conductivity by means of a guarded-hot-plate instrument. For a material to be classified as a thermal insulator, it must exhibit low thermal conductivity throughout this test — which, though not identical, is comparable to ISO 8302.

Infra-red spectroscopy uses the fact that molecules in certain solids, liquids, and gases absorb IR radiation at characteristic frequencies. Molecules in a sample can be identified by subjecting test samples to varying frequencies and correlating absorption peaks with a standard database of IR absorption spectra.
