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).

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

NEMA enclosure types

NEMA defines standards for various grades of electrical enclosures typically used in industrial applications. Each is rated to protect against designated environmental conditions. A typical NEMA enclosure might be rated to provide protection against environmental hazards such as water, dust, oil or coolant or atmospheres containing corrosive agents such as acetylene or gasoline. A full list of NEMA enclosure types is available from the NEMA website.

Below is a list of NEMA enclosure types; these types are further defined in NEMA ICS 6: Enclosures standard.

NEMA Type	Definition
1	General-purpose. Protects against dust, light, and indirect splashing but is not dust-tight; primarily prevents contact with live parts; used indoors and under normal atmospheric conditions.
2	Drip-tight. Similar to Type 1 but with addition of drip shields; used where condensation may be severe (as in cooling and laundry rooms).
3, 3S, 3X	Weather-resistant. Protects against weather hazards such as rain and sleet; used outdoors on ship docks, in construction work, and in tunnels and subways. 3X includes corrosions.
3R	Intended for outdoor use. Provides a degree of protection against falling rain and ice formation. Meets rod entry, rain, external icing, and rust-resistance design tests.
4 and 4X	Watertight (weatherproof). Must exclude at least 65 GPM of water from 1-in. nozzle delivered from a distance not less than 10 ft for 5 min. Used outdoors on ship docks, in dairies, and in breweries. The 4X model has corrosion resistance.
5	Dust-tight. Provided with gaskets or equivalent to exclude dust; used in steel mills and cement plants.
6 and 6P	Submersible. Design depends on specified conditions of pressure and time; submersible in water or oil; used in quarries, mines, and manholes.
7	Hazardous. For indoor use in Class I, Groups A, B, C, and D environments as defined in the NEC.
8	Hazardous. For indoor and outdoor use in locations classified as Class I, Groups A, B, C, and D as defined in the NEC.
9	Hazardous. For indoor and outdoor use in locations classified as Class II, Groups E, F, or G as defined in the NEC.
10	MSHA. Meets the requirements of the Mine Safety and Health Administration, 30 CFR Part 18 (1978).
11	General-purpose. Protects against the corrosive effects of liquids and gases. Meets drip and corrosion-resistance tests.
12 and 12K	General-purpose. Intended for indoor use, provides some protection against dust, falling dirt, and dripping noncorrosive liquids. Meets drip, dust, and rust resistance tests.
13	General-purpose. Primarily used to provide protection against dust, spraying of water and noncorrosive coolants. Meets oil exclusion and rust resistance design tests.

 

NEMA enclosure ratings are similar to IEC IP Codes and can offer the same protections, but cannot directly be mapped.

 

 

Electrical Panel Board Final Inspection and Testing

Final Inspection and Testing

 QCI Carry out ROUTINE TESTS as per IEC 60439-1 standards. The following minimum tests

must be performed:

 Visual inspection test – Checking of the complete switchboard in accordance with IEC

60439-1 standards and approved drawings. Checking of Integrity of Wiring, Tightness of all

joints, and Torque test on all bus connections, etc.

 Di-electric Test – Done using a MEGGER (verification of Insulation resistances between

phases, phase-neutral, phase-earth and neutral-earth). This test is also verified by a HIPOT

test using a 2.5kV test between phases for 1min.

 Mass Continuity Test – To check if there is proper earth continuity from end of the

switchboard to the other. This test can be checked
