Sand And Dust Chamber

Overview

These chambers are used for checking ingress of sand and dust in luminous, plastics and automotive IP5X and IP6X tests.

Needs specifications of:

• IEC 60529, DIN40050, IP5K0, IS9000 – 1981 Part 12,
• JSS 55555 – test No.14.
• SAE J575 sub paragraph GJ-ISD0207
• ASTM C150-77
• Salient features:
• Workspace dimensions: 1000(W)x1000(D-front to back) x 900(H) mm
• Temperature range: Ambient to 55°C.
• Humidity: Less than 50% RH(workspace should be dry).

Instrumentation:

1. By microprocessor based temperature controller.

2. Agitation timer.

3. Settling timer.

4. Cycle counter.

Dust used for this test shall be dry.

• Approved dust types: Equivalent to Arizona dust, Portland cement dust and 213 silica sand.
• Dust measuring device: This device shall be kept at any place within the chamber. The
• Dust laden air will be circulated and dust is allowed to settle down. The amount of
• Dust collected for different agitation time and settling time is measured and recorded.
• Viewing window: Full size viewing window & wiper along with halogen lamp.
• Port hole with rubber stopper.
• SS wire mesh shelf above agitator.

Safety:

•  MPCBs for motor.
• High temperature cut out in case of temperature overshoot.
