This document replaces GB/T 4798.2-2008 "Environmental conditions existing

in the application of electric and electronic products - Part 2: Transportation".

Compared with GB/T 4798.2-2008, in addition to structural adjustments and

editorial changes, the main technical changes are as follows:

a) In "Scope", add groups of environmental parameters and their severities

of "handling" (see Clause 1);

b) In Clause 3 "Terms and definitions", modify the terms "weather-protected"

and "non-weather-protected" (see 3.1 and 3.2; 3.1 and 3.2 of the 2008

edition);

c) Add the description of "the effects of short-term extreme environmental

conditions" and "the effect of long-term subjection to non-extreme

environmental stresses" (see Clause 4);

d) For "K Climatic conditions", "S Mechanically active substances" and "M

Mechanical conditions", replace old classes with new classes (see 5.2,

1996 and revised for the second time in 2008;

- This is the third revision.

Classification of environmental conditions -

Classification of groups of environmental parameters

and their severities - Part 2: Transportation and

handling

1 Scope

This document classifies the groups of environmental parameters and their

severities to which a product is subjected while being transported and handled.

The most commonly used methods of transportation and handling have been

taken into account, including the following:

- road transport: cars, trucks;

- rail transport: trains, trams;

- water transport, inland and maritime: ships;

- air transport: aircraft, jet, propeller, helicopter;

- handling equipment: cranes, transport lifts, cableways, persons;

- conveyors;

- hand trollies.

The environmental conditions specified in this document are those that the

product can be exposed to while transported and handled. If the product is

packaged, the environmental conditions apply to the package containing the

product. If the product is unpackaged, the environmental conditions apply to the

product.

Conditions for storage are given in IEC 60721-3-1.
