2, Machinery UL certification

UL listing：

Equipment in this category is designed to be programmed for a specific manufacturing application, such as assembly of components, packaging, sorting, or counting of parts, or hole punching or cutting, etc. The equipment may also incorporate manufacturing processes involving heating or cooling, drying, or gluing of parts, and is intended to be installed in accordance with NFPA 70, National Electrical Code, and NFPA 79, Industrial Machinery.

HOW THE PROGRAM OF UL LISTING OF MACHINERY – WORKS

1. Preliminary investigation

Product overview      

A physical inspection / construction overview of the product would be undertaken as a first step including the following subsystem as applicable.    

I. Electrical system including control Panel

II. Mechanical system

III. Hydraulic system

IV. Pneumatic system

V. Lubrication system

See the following item:

Size of Devices (including enclosures and components)  

Individual Component Requirements like Circuit breakers, contactors, push-button / selector switches, transformers etc.,

Components that can be used without evaluation  

Panel and other Enclosure Environmental Type Rating and tests  

Spacing (including branch and control circuits and other circuits)  

Wire Bending Space in Panels and Field Wire Sizing

----

Etc

2．Field check and test

- Anticipated Tests for Final UL Listing of Machine, as per UL508 and SU2011。

Temperature Test,

Dielectric Voltage Withstand Test,

Single Phasing Test,

Fan Locked Rotor Test,

Blocked Filter Test,

Drive Motor Locked Rotor Test,

Emergency Stop Operation Test (including two-handed controls), and

Breakdown of Components Test.

UL machinery standard applied

UL Subject 2011 – Factory Automation Equipment

UL 50 – Enclosures for Electrical Equipment

UL 508 – Industrial Control Equipment

CE certification program:

Step1: Create a CE project group

Step2: Prepare a sample for our safety test and structural check

Step3: Technical document principium review

Step4: Safety check and pre-test of machinery

Step5: Provide modification report

Step6: Modify equipment for double check

Step7: Prepare test report and compiled the TCF

Step8: Submit the TCF in order to obtain NB’s authorization

Step9: Affix CE mark.
