Glow wire testing is performed by IEC61439-1

Overview of the main verification changes (IEC 61439 vs IEC 60439)

> Design verification

 

·         Increased requirements for insulating materials and transient overvoltages withstand tests.

·         Temperature rise verification:

ü  Verification by test of each functional unit loaded alone with its rated current

ü  Clear methods for the selection of representative samples of an Assembly system to be tested

ü  Test done in 4 steps: individual functional units, main and distribution busbars, and complete

Assembly

ü  Heating resistors only allowed to simulate circuits adjacent to a circuit under test

ü  Possible verification by comparison with a tested design under strict conditions, including derating

ü  Exemption of test (calculation) only allowed up to 1600 A instead of 3150 A under strict conditions,

including a 20% derating.

·         Possible short-cricuit withstand verification by comparison with a tested design under strict

condition

·         200 operating cycles instead of 50 for locking, interlocking and withdrawable parts

·         Lifting test (from IEC 62208)

·         Corrosion resistance test for metallic parts (from IEC 62208).

 

> Routine verification

 

ü  More detailed list of the verifications

ü  More severe requirements for clearances

What is IP69K?

The IP69K rating is for applications where high pressure and high temperature wash down is used to sanitize equipment.

The IP69K test specification was initially developed for road vehicles, especially those that need regular intensive cleaning (dump trucks, cement mixers, etc), but has been widely adopted in the Food & Beverage industries as a test of products to withstand sanitary washdown.

 

What does IP69K mean?

In the IEC 60529 rating system, IP6 refers to the product’s ability to resist ingress of dust. The 69K refers to the product’s ability to resist ingress of high temperature (Steam)/high pressure water.

How is the product tested?*

• Products rated to IP69K must be able to withstand high-pressure and steam cleaning.

• The test specifies a spray nozzle that is fed with 80 °C water at 80–100 bar (~1160-1450) and a flow rate of 14–16 L/min.

• The nozzle is held 10–15 cm from the tested device at angles of 0°, 30°, 60° and 90° for 30 seconds each.

• The test device sits on a turntable that rotates once every 12 seconds
