3 Definitions
For the purposes of this part, the following terms and definitions apply.
This clause of GB 4706.1-2005 is applicable except as follows.
3.1.9 Replacement:
Normal operation
operation of the appliance under the following conditions:
Appliances are operated in cycles, each cycle being initiated every 10min, bowl covers being open or closed whichever is more unfavorable. If the cycle is not automatically terminated, the appliance is operated for 15s, or for the period specified in the instructions, whichever is longer.
If warm air is provided for drying, the drying cycle is initiated immediately after the end of the showering cycle, unless the sequence is automatic.
The excrement tank of mouldering toilets is empty or filled with peat, whichever is more unfavorable.
Package toilets shall be provided with bags.
For freezing toilets, 0.3L of water having a temperature of 37℃ is added each cycle, controls being adjusted to the lowest temperature. They are also operated without water.
Shower units are supplied with water at the most unfavorable pressure that provides an effective spray.
