ETL Tests to CSA and UL Standards Undergone by the MedReel

The MedReel has undergone and been found compliant with applicable medical requirements of the Standard for Cord Sets and Power Supply Cords CSA C22.2 No 21-95.

In addition, the Medreel conforms to the following CSA and UL Specifications testing: CSA22.2 #0-M91, C22.2 #0.4.M 1982, C22.2 #21-M94, and UL 355 6th Edition. The following is a summary of each of these tests :

General (UL 355 C1-17)
The Medreel internals should be compliant with the proper type of electrical fitting and components so no shorting can occur. Endurance Test (UL 355 C1–14) The reel was attached to a machine which cycled the cord in and out of the reel 6,000 times at right angles to the opening. There could not be any signs of wear on the cord at the end of the test.

Temperature (UL 355 C1–19 and CSA C1- 6.12)
The blades of the male fitting are connected to each other with 38mm of copper wire, one end soldered to each blade, and then subjected to a current equal to the acceptable ampacity of the cord. It should be capable of carrying the rated current of the cord without a temperature rise of more than 30° C.

Dielectric Voltage Factory (UL 355 C1–20)
The equipment at the conclusion of manufacture, before shipment, shall withstand for one minute without breakdown, the application of 1,000V ac between live parts and exposed non-current-carrying metal parts. The factory test may be made at the existing room temperature. As an alternative, a potential of 20% higher may be applied for one second.

Dielectric Strength (CSA C1-6.18)
The Medreel must withstand, without breakdown, the application of 1,000 V ac volts for a period of 1 minute plus twice the rated voltage applied between any two conductors.

Strain Relief (CSA 6.4)
The Medreel internals were checked so ensure that a pulling force of 133 Newtons exerted on the cord would not be transmitted directly to binding screw terminals of a fitting.

Impact (UL 746C)
The cord reel was cooled to -35°C ± 2°C and secured to a piece of plywood laid on a concrete floor. While the unit was still cold, a steel sphere 2" in diameter weighing .74 kg (1.18 lbs) was dropped from a height of 1.5 meters on to three places on each side of the cord reel. No cracks could result.

Note: The lattice structure of the plastic changes due to the dessication of water from the plastic at this low temperature, reducing the it's ability to withstand impact without fracturing. Attempts to strengthen the plastic case by increasing the thickness of the sides and by adding molded-in ribs were marginally successful so the addition of an exterior steel cladding was the only option to successfully pass this test.

Crush-Resistance (UL 746C)
The reel was placed on its side on a concrete floor over top a sheet of plywood. A plywood square 1' X 1' was placed on the reel and a weight of 220 lbs. was lowered on to the plywood. No breaking or cracking could result.

Flame (UL94 – 94V-2 Rating)
6" x 6" plastic samples were subjected to a 5" flame with a 1.5" inner blue cone for 5 – 5 second intervals. The time of flaming and flowing was recorded after the 5th interval. This test determines if flaming material drips from the specimen and whether burn through occurs. Self-extinguishing must occur in less than 25 seconds on the average of all 5 tests.

Freezing Rain (CAN/CSA – 22.2 #94-M91) (CSA/UL Special Purpose Enclosures Sleet and Formation of Ice Test)
The Medreel was laid on its side in a –7°C room and sprayed for one hour with a fire hose. After 20 mm of ice had accumulated on a horizontal control bar the reel was tested to ensure that the mechanisms operated normally under this ice laden condition. After thawing, the reel was checked to ensure that no water was inside.

Heating (CSA C1 – 6.15)
The reel is subjected to a 60 Hz current equal to the current rating of the cord until constant temperatures are attained. It should not at any point attain a temperature high enough to constitute a fire hazard.

Abnormal Heating(CSA C1 - 6.16)
The Medreel was placed on four plies of cheesecloth with four more plies of cheesecloth placed on top. With a third of the cord left in the case, an electrical flow 110% over the cord's rated capacity is applied for a period of 7 hours. Normally, heat builds to the point of reducing the reel to a charred mass before the test time is completed, however, with the breaker installed, the electricity flow is regulated and the Medreel passed the test.

Hosedown(CSA 6.8.2)
The Medreel was secured to a piece of plywood attached to the concrete floor. A 1" hose issuing 60 gallons of water per minute was played on the reel for 5 minutes. The stream was specifically directed at the joints and cord reel opening from a distance of 3 meters. The reel was then cut apart and there could not be any water inside.

Cord Reels, Switches or Other Intermediate Devices Intended for Use in Other than Dry Locations (CSA 6.20)

Enclosure 4X Rating

An added bonus was achieving an Enclosure 4X designation after the hose down and freezing rain tests. In order to receive this rating the product must allow NO WATER to enter the case during these three successive tests:

* A hose down test followed by a
* freezing rain test followed by another
* hose down test, all on the same reel.
