How to understand the seventh paragraph of INTRODUCTION

The seventh paragraph of introduction as below:
Individual countries may wish to consider the application of the standard, as far as is reasonable, to appliances not mentioned in a part 2, and to appliances designed on new principles. In this case consideration should be given to defining normal operation, specifying the classification of the appliance according to Clause 6 and specifying whether the appliance is operated attended or unattended. Consideration should also be given to particular categories of likely users and to related specific risks such as access to live parts, hot surfaces or hazardous moving parts.

Because standards generally lag behind technology, a new product may emerge for which no standards have been established to evaluate the product, in which case the first part of the standards can generally be used to evaluate the product. In this case, it is still necessary to categorize and define the product in accordance with the standards, including consideration of the use of the population, etc., which means that the product will be evaluated in a similar way as conventional products.
Products need to be evaluated in five areas: protection against the risk of electric shock, protection against touching moving parts, protection against thermal injury, protection against the risk of fire, and protection against the risk of chemical and radiation.
