Information typically required for testing
To help our customers prepare for their visit to GPCL/ETG for
product testing, we have put together this guide. This guide will give
you an idea of what is required to test a product and what must be
considered before testing can even begin.
Instructions
The following information is required to prepare for testing.
Even
if equipment will be undergoing only an initial evaluation, product
developers new to the compliance environment may benefit by reviewing
these requirements.
- Description
- Brief description of the Equipment Under Test (EUT),
including
Official name and model number. What does the machine do? Use a
descriptive sentence from advertising literature.
- Intended Environment
- Where will the EUT be installed and used? In what
environments
(e.g., residential, commercial. light industry, or heavy industry) will
it be located?
- Physical Size and Weight
-
- How many units make up the EUT?
- What are its dimensions and weight?
- Is the floor loading reasonably well distributed?
- Test System
- Block diagram of system under test and supporting equipment
(can be
hand drawn). Diagram should show what is in the test area and what is
ourside the test area. It should include cables, EUT, and peripherals.
- Test Requirements
-
- What standards will be applied? Regulatory agency,
special
(e.g., Telcordia) or initial evaluation (no compliance) measurement?
- What tests will be performed? What limits will be
applied?
- What severity levels will be used when performing
immunity
testing (if applicable)?
- Cabling
- Cable diagram or list of cables including cable lengths of
system under
test. Are the cables shielded, non-shielded, twisted pairs, or other?
- Power
-
- What are the power requirements (line voltage and
current)
for the EUT and support equipment?
- How many power cords are there for the EUT and support
equipment?
- What type of power connectors are used? (Give range:
50 Hz -
60 Hz required.)
- Grounding
- List any special grounding requirements.
- Auxiliary Equipment
- List any equipment required to operate or serve as loads
for the EUT.
- Modes of Operation
-
- How will the EUT be operated?
- How many modes will be tested?
- How many line voltages are required for the test?
- When only one mode is to be tested, provide rationale
for
selecting that mode. Example: This mode exercises all circuits and
draws the most power from the power source.
- Configurations/Ports
-
- How many EUT configurations will be tested? (Use
typical
installation practices or regulatory requirements such as ANSI C63.4
for FCC tests.)
- How many ports are there and how will they be used?
- Is there shielding on the EUT signal ports,
plug-ins,
shelves, nodes, etc?
- Failure Modes
-
- A definition of what constitutes a failure. How will
the
errors be identified and monitored? (State level: none, brief shutdown,
keep within specs, etc.)
- What is the performance degradation criteria for
immunity
tests?
- What is the critical error that will show performance
degradation at an unacceptable level?
- How do you monitor this performance degradation?
(e.g., via
test set, remote simulation, etc.)
- Do you need special methods to monitor performance
degradation? (e.g., via cameras, lighting, hardwire telemetry, etc.)
- ESD Test Points
- A diagram or photograph of EUT showing the ESD test points.
(CE testing only.)
- EUT Frequencies
- List all clock/data frequencies.
- Software/Firmware
- Will special test software be necessary to populate CRT and
data transmission?
- Security
- What are your security requirements? Must EUT be hidden or
camouflaged while at GPCL?
- Other Considerations
- If you have support or monitoring equipment that will not
be in the test chamber with your EUT, are the cables to that equipment
at least thirty feet long?
