Testing Skills

- PG 192

1. Measure Voltage

2. Measure Current

3. Measure Leakage Current

4. Dielectric Withstand Test (DWT)

5. Temperature Test• Thermocouple

• Change of Resistance



Voltage Measurement

- PG 193

We measure voltage for the following reasons:

• To determine correct types of connections to power supply

• To determine shock hazards

• To determine spacing in products that is based on voltage

• To find locations where circuit becomes compliant with requirements to allow no further evaluation



Current Measurement

- PG 194

We measure current for the following reasons:

• Because the amount of current used will determine the size of supply conductors and wiring used

• Determine if a unit is operating properly (does the current match the ratings)

• To determine the existence of a fire hazard

• To find areas (along with voltage) which are considered safe so no further evaluation is needed



Leakage Current Measurement

- PG 195

We measure leakage current for the following reasons:

• Leakage current is the current available from parts which a user can touch. We measure this to make sure values are not high enough to hurt (or even feel in some cases) someone who can touch the product.

• Your lab should have a variety of leakage networks, and perhaps a variety of test circuit boxes. Be sure you ask somebody how to set them up, such as measurement to ground or measurement between parts of the equipment.

• Note that testing sometimes must be performed after environmental conditioning

• Be sure to follow sequence



Dielectric Voltage Withstand Test

- PG 196

What is DWT?

A high voltage, low current test to find breakdowns

in the insulation of a product



Dielectric Voltage Withstand Test

- PG 196

When is a DWT indicated?

• Indicated where spacings are not sufficient

• Indicated when there are nicks or cuts in insulation of wire

• Indicated where there issues with insulation becoming conductive

when heated

• Simple test to find these issues that need to be looked at further



Temperature Testing

- PG 197

Temperature Testing is a basic test performed on all products to make sure the product will operate properly for the expected length of time



Creepage & Clearances

Creepage Distance- Shortest path that follows surface between two points

Clearance- Shortest path between two points through air

- PG 198




- PG 198



Measurement Uncertainty

• Utilize calibrated test equipment in lab

• If you use non Intertek calibrated equipment, then verification of measurement equipment is required

• In the US, we follow CTL Decision Sheet 251B to comply

• There is a more formal course on the detailed rules which is available upon request. This course will be needed if you ever work in the UK or Europe.

Customer Focus

- PG 204



Customer Focus

• Customer Complaints

• Complete Project Management

• RFQ Process (Sales Interface)

• Contact Client

• PCD Deadlines and Queue Times

- PG 205



Customer Service

Good Customer Service = Lasting relationships

Average Customer Service = Steady relationships that could be lost

Poor Customer Service = Lost business

- PG 206



Customer Service – Why bother?

Statistics

• For every one customer that complains, seven do not!

• Many customers move away without telling you why.

• An unhappy customer is likely to tell 30 other people about their experience.

- PG 207



Complaints

What is a complaint?

How can complaints be made?

- PG 208



Complaints and SOP 7.14.1

Use SOP 7.14.1 for significant complaints

• Validity of test data is questioned

• Threat of lawyer or lawsuit

Examples of lower-level complaints:

• Customer disputes a bill

• Customer did not receive deliverable

• Customer has not heard back from engineer or sales person…

• Customer PO does not match our invoice

• Customer has not received a quote

- PG 209



Internal Request for Quote Template

Internal Request for Quote (IRFQ)

Benefits to Engineering and Operations

• Sales is training to do quotes

• PC uses RFQ to schedule time

• All information in one form

Benefits to Sales

• Twenty four (24) hour turn-around time from Operations

• PC uses RFQ to schedule based on time need and not $$ quoted

• Able to quote faster and more independent

- PG 210



Signed Order Template

Contact your reviewer and client

Signed Order Template

- PG 211



Promised Completion Dates

Promised Completion Dates (PCDs)

• Set five (5) days after the last day of the project

• Important to meet all PCDs

• Notify PC if a project need to be pushed out for some reason, such as extra testing

Waiting for Client Information – More than 48 hours

• Ensure the communication process was followed

• Write a Letter Report so the project can be invoiced

• A PCOR will be at the discretion of Sales and Operations

Queue Time – 2 day times

• Use of the Network

- PG 212



Class Exercise

Typical Testing

Locate the standards noted in your Participant Guide and

identify the difference in how testing is presented

When you get to UL 1598, please leave the standard open and

accessible on your computer

- PG 237



Typical Test Program

• How to create a Test Program

• Discuss data sheet creation

• Examine the overall program

• Consider the order in which tests are performed

- PG 238



Why do we perform tests?

• Compliance with the standard

• Allows the manufacturer more latitude in how he/she designs products rather than simply defining the construction of the product to meet safety requirements

- PG 239



When there is more than one standard

Sometimes, there is more than one standard in a report

- PG 241



Reasons

• Clients want to have more than one standard on a product due to selling the same product in more than one country

• We can use multiple standards when the product complies with all the requirements in all standards used

- PG 241



When can we use more than one standard?

We need a separate report when the requirements in the standard conflict

- PG 241



Separate Reports

• US and Canadian Standards

• Two Construction Reviews (unless standards are harmonized)

• When we can include two standards in a report

• When we are required to create separate reports

• French Markings for Canada

- PG 241



Class Discussion

• What standards are commonly used in your lab?

• Special circumstances in Safety Testing

• What if I don’t have all of the materials that I require when I start a job?

- PG 242



Summary

• Review of Job Process Flow

• Testing Paperwork

• Voltage Measurement

• Current Measurement

• Leakage Current Measurement

• Dielectric Voltage Withstand Test

• Creepage and Clearances

• Measurement Uncertainty

• When to use more than one standard

• Typical Testing

• Typical Standard Use
