BS EN 60601-2-37:2008+A1:2015

Clause1 of the general standard applies, except as follows: 201.1.1 *Scope Replacement: This International Standard applies to the basic safety and essential performance of ultrasonic diagnostic equipment as defined in 201.3.217, hereinafter referred to as me equipment. If a clause or subclause is specifically intended to be applicable to me equipment only, or to me systems only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to me equipment and to me systems, as relevant. Hazards inherent in the intended physiological function of me equipment or me systems within the scope of this standard are not covered by specific requirements in this standard except in 7.2.13 and 8.4.1 of this standard. NOTE See also subclause4.2 of this standard. This particular standard does not cover ultrasonic therapeutic equipment. Equipment used for the imaging or diagnosis of body structures by ultrasound in conjunction with other medical procedures is covered. 201.1.2 Object Replacement: The object of this particular standard is to establish particular basic safety and essential performance requirements for ultrasonic diagnostic equipment as defined in 201.3.217. 201.1.4 Particular standards Replacement: In the IEC60601 series, particular standards may modify, replace or delete requirements contained in the general standard as appropriate for the particular me equipment under consideration, and may add other basic safety and essential performance requirements. A requirement of a particular standard takes priority over the general standard. For brevity, IEC60601-1 is referred to in this particular standard as the general standard. Collateral standards are referred to by their document number. The numbering of sections, clauses and subclauses of this particular standard corresponds to that of the general standard with the prefix “201” (e.g. 201.1 in this particular standard addresses the content of Clause1 of the general standard) or applicable collateral standard with the prefix “20x” where x is the final digit(s) of the collateral standard document number (e.g. 202.6 in this particular standard addresses the content of Clause6 of the 60601-1-2 collateral standard, 203.4 in this particular standard addresses the content of Clause4 of the 60601-1-3 collateral standard, etc.). The changes to the text of the general standard are specified by the use of the following words: \'Replacement\' means that the clause or subclause of the general standard or applicable collateral standard is replaced completely by the text of this particular standard. \'Addition\' means that the text of this particular standard is additional to the requirements of the general standard or applicable collateral standard. \'Amendment\' means that the clause or subclause of the general standard or applicable collateral standard is amended as indicated by the text of this particular standard. Subclauses, figures or tables which are additional to those of the general standard are numbered starting from 201.101, additional annexes are lettered AA, BB, etc., and additional items aa), bb), etc. Subclauses or figures which are additional to those of a collateral standard are numbered starting from 20x, where “x” is the number of the collateral standard, e.g. 202 for IEC60601-1-2, 203 for IEC60601-1-3, etc. The term \'this standard\' is used to make reference to the general standard, any applicable collateral standards and this particular standard taken together. Where there is no corresponding section, clause or subclause in this particular standard, the section, clause or subclause of the general standard or applicable collateral standard, although possibly not relevant, applies without modification; where it is intended that any part of the general standard or applicable collateral standard, although possibly relevant, is not to be applied, a statement to that effect is given in this particular standard.
