Highly Accelerated Stress Test


The sped up pressure test hardware utilized for HAST has capacities conceived fundamentally for predisposition testing with a consistent voltage or sign applied. Hardware with example signal terminals of up to 72 pins is accessible. Two gear types are accessible. The two-mode models have two control modes (unsaturated control and wet immersion control). The M models have three control modes (dry/wet-bulb temperature control, unsaturated control and wet immersion control). The M models consent to IEC-60068-2-66 (a worldwide norm).

EHS-431M Medium-sized HAST Chamber (introduced at Kobe Test Center)

A HAST test framework supporting examples too enormous to even consider fitting in regular HAST chambers. Has around multiple times the limit of regular models, with test chamber measurements every over 30% bigger.

Supports testing of four-cell sun based battery modules that were beforehand untestable.

Has 72 arrangements of example signal terminals (144 pins) to help air HAST and wide-range HAST testing (both portrayed beneath).

Different sorts of HAST testing

Air HAST and wide-range HAST are two other HAST strategies accessible notwithstanding the government sanctioned test modes (dry/wet-bulb temperature control, unsaturated control and wet immersion control). Air HAST and wide-range HAST are intended to create reproducible test results with exact relationships to brings about the field, and to limit test times. They are portrayed beneath.

Air HAST Chamber (introduced at Utsunomiya Test Center)

Traditional HAST testing is in far reaching use as an IEC/JIS-consistent water fume based sped up test technique for assessing the stickiness obstruction of electronic parts fixed in materials like plastic.

Notwithstanding water fume, oxygen noticeable all around can likewise cause disappointments in the market because of oxidation close to surfaces, so air HAST testing is utilized for some test tests and targets. This technique centers around the air in moist warmth tests. It adds air to customary HAST tests, for sped up testing of surface oxidation.

Wide-range HAST Chamber (introduced at Utsunomiya Test Center)

While the low temperature/stickiness scopes of standard temperature/moistness chambers bring about exorbitantly long test times, temperature and dampness are too high in HAST conditions. Wide-range HAST hardware was made to address the issue for gear supporting climate testing halfway between these two test conditions.

In particular, wide-range HAST testing empowers soggy warmth tests at temperatures of around 100°C.

It upholds sped up testing of tests for which HAST testing can't be utilized, for example, materials with reasonably low glass change focuses or heat opposition temperatures.

Test model

Sped up bristle testing

Sped up testing of covering/lighting gear materials (LEDs, plastics) and sunlight based boards (testing done when oxygen is viewed as a disintegration factor)

Sped up testing done when air might be inadequate factor for connection with temperature/mugginess testing at 85°C/85% RH
