Class 1 Text version. Top left image Placard and label for Class 1.1, 1.2 and 1.3. Square on a point. Orange background. Starting from the bottom, the number 1, above it, asterisk which corresponds to the Compatibility Group Letter and double asterisk for Division. Symbol of an exploding bomb in top portion.

Division 1.6 Extremely insensitive articles which do not have a mass explosion hazard Class 1 Dangerous Goods Examples amp Labels. Commonly transported Class 1 Dangerous Goods include ammunitions, fireworks, air bag inflactors and fuse, etc. Class 1 Dangerous Goods Label. The picture below shows the hazard symbols label for Class 1 dangerous

Class 1 Explosive substances and articles. Class 1 contains substances and articles which pose a hazard due to explosion. Items in Class 1 are further divided into divisions 1.1 - 1.6 depending on the nature of the explosion hazard and the sensitivity of the item. A compatibility group, consisting of a single letter, is also assigned to each item.

Class 1 and Class 2 appliances are all powered by mains voltages. Both classes are required to provide at least two levels of protection to the end user. - If there is a double box symbol on the rating plate it must be a Class 2 appliance. Typically computers and photocopiers are Class 2, most plastic power tools would also be Class 2

Class 3 devices will often carry a symbol that contains three vertical stripes within a diamond. The Importance of Each PAT Class The PAT classes, as well as the appliance category, are important because they are used collectively to determine what type of PAT testing is required and how regularly such tests should be carried out.

Class III symbol. A Class III appliance is designed to be supplied from a separated extra-low voltage power source. The voltage from a SELV supply is low enough such that under normal conditions a person can safely come into contact with an energized conductor without risk of electrical shock. The additional safety features required by Class I

The Class 2 label is related to power supply, not safety. It also follows another standard, UL 1310. Class III. Class III appliances are identified by the Class III symbol. Examples of Class III appliances are laptops, mobile phones, and low energy light bulbs. Class III appliances use an isolating transformer.

Class 1 electrical equipment is an equipment with at least one provision for basic protection and with means for protective-equipotential-bonding for fault protection this term is defined in the IEC 60050-1952021. Electric kettle is an example of class 1 equipment

Class 2 appliances are considered to be safer, because of this double insulation, so it is important that your appliances are classified correctly, because if a Class 1 appliance didn't undergo the full range of testing, then a safety or performance issue may not be identified and hence a hazard will always exist until it potentially causes a

Class II equipment typically includes smaller appliances like electric drills, hairdryers, and table lamps. Class II appliances can be identified by a square within a square symbol . This symbol is usually on the label with the power and voltage rating. Alternatively, it is sometimes embossed directly on the plastic case. Conclusion
