2、plementation of EN ISO20877:2011. It supersedes BS EN 12784:2000 which is withdrawn.It is the considered opinion of the UK committee that the testmethods contained in EN ISO 20877 could be potentially misleadingfor two reasons. Firstly the insulation against heat test methoddescribed is not a whole
3、shoe test but is influenced only by theproperties of the sole unit. In addition the test method described forinsulation against cold offers limited differentiation between styles.Therefore caution should be employed when using or reviewingdata generated by these methods.The UK participation in its p

The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interes
17、ted in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical C
18、ommission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the techni
19、cal committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
