GB/T 2423.18 Environmental Testing for Electrical and Electronic Products - Part 2: Test Methods, Test Kb: Salt Spray, Alternating (Sodium Chloride Solution) (GB/T 2423.18-2000, IEC 60068-2-52:1996, IDT) GB/T 2893.1 Graphical Symbols - Safety Colors and Safety Signs, Part 1: Design Principles for Safety Signs in Workplace and Public Areas (GB/T 2893.1-2004, ISO 3864-1:2002, MOD). The following terms and definitions apply to this part of GB/T 4706. This chapter of GB 4706.1-2005 applies except for the following content. Substitution:

Normal operation: Instruments that are not involved in the following but can complete an operational function should be operated according to the specified conditions as much as possible.

. The bread toaster is loaded with the maximum number of white bread slices specified in the instructions and operates in a cyclic manner, each cycle consisting of one working cycle and one rest cycle. The freshness of the bread is recommended to be stored for about 24 hours, and the size of the bread slices is about 100 mm × 100 mm × 10 mm, with a rest period of 30 seconds or the shortest time required for automatic controller reset, whichever is longer. Replace bread slices during each break. The working cycle is based on adjusting the controller to turn the bread into a burnt yellow color. For non automatic controlled bread toasters, as soon as the bread slices turn burnt yellow, this work cycle ends. The bread toaster with a baking roll device is loaded with the maximum number of rolls specified in the instructions and operates in a cyclic manner, each cycle consisting of a working cycle followed by a rest period of 30 seconds. Flip or replace rolls during each break. Adjust the control device according to the instructions. If the instructions do not specify how to operate, adjust the controller to the baking position. Place one or more sandwiches on the sandwich baking accessory, and the placement should be in the most unfavorable position when using according to the user manual. Each sandwich consists of two pieces of white bread sandwiched with a suitable piece of cheese. The area of the cheese is the same as the area of the bread, with a thickness of about 5 mm. Then, the toaster cycles according to the user manual, each cycle includes a baking cycle, followed by a rest cycle of 30 seconds or the shortest time required for automatic controller reset, whichever is longer. Note: Processed cheese and cheese that easily melts when heated are suitable. The rotating grill works by placing the load shown in Figure 102 on the rotating baking fork. A waffle cake furnace equipped with a temperature controller should operate with the temperature controller adjusted to the highest set position. When other waffle furnaces are running, the power can be turned on and off through a switch to maintain the central temperature of the heated surface at 210 ℃± 15 ℃
