What is UL temperature Index?
What is UL temperature Index?
The Thermal Index value can be thought of as the maximum temperature below which the material will retain sufficient properties (typically 50% of the original value) for the intended application over a reasonable product lifetime.
How can I check my RTI?
Sets of test specimens are placed in ovens at four different preset temperatures. At intervals, specimens are removed and tested for specific mechanical or electrical properties. The results are plotted on a time versus property graph until the property being tested declines to 50 percent or less of its initial value.
What does an RTI of 85% mean?
RTI indicates the output airflow rate from the cooling package to the equipment such as racks. It also shows the existence of re-circulation or by-passed air. If the RTI is more than 100%, it indicates re-circulation and if the RTI is less than 100% the flow is by-passed.
What is the full form of RTI?
The Right to Information Act, simply known as RTI, is a revolutionary Act that aims to promote transparency in government institutions in India.
How is RTI ramp score calculated?
The measurement is only taken when the other three tires are still on the ground. The distance traveled up the ramp is then measured and is divided by the vehicle’s wheelbase and finally multiplied by 1000 to give a final RTI score.
What is RCI and RTI?
While the Rack Cooling Index (RCI) ® is a measure of how effectively the equipment racks are cooled within industry thermal guidelines and standards, the Return Temperature Index (RTI) is a measure of the energy performance of the equipment room air-management system.
What is RCI hi?
RCIHI is a measure of the absence of over-temperatures. 100% means that no temperature is above the maximum recommended. Less than 100% means the greater the probability (risk) that equipment experiences temperatures above the maximum allowable (hotspots)
How do I get a UL yellow card?
To get the Yellow Access Card, you have to head to the new Shipwreck POI and start slaying the zombies as part of the Outbreak event. It doesn’t matter how many you kill, but the very last zombie drops the Yellow Access Card.
Who is RTI officer?
PIOs are officers designated by the public authorities in all administrative units or offices under it to provide information to the citizens requesting for information under the Act.
What does RTI stand for in UL 746B?
RTI Relative temperature index (RTI) One of the most important tests to determine a given plastic’s fitness for long-term ambient heat is the UL Standard 746B, Polymeric Materials, Long-Term Property Evaluation. As a data point, it’s shortened to Relative Thermal Index (RTI).
What does the relative temperature index ( RTI ) mean?
From Wikipedia, the free encyclopedia The Relative temperature index (RTI) is a characteristic parameter related to the thermal degradation of plastic materials. The RTI is part of the thermal-aging program of the UL 746B standard from UL.
What was the purpose of the RTI test?
Underwriters Laboratories Inc. (UL) developed RTI to test the deterioration of insulating materials in electrical devices over time. Maximum service temperature for a material where a class of critical property will not be unacceptably compromised through chemical thermal degradation.
What does RTI stand for in electrical category?
This spans over the reasonable life of an electrical product, relative to a reference material having a confirmed, acceptable corresponding performance defined RTI. The electrical RTI is associated with critical electrical insulating properties.
