IEC 60335 -2-91, Household and similar electrical appliances   Safety - Part 2 -91: 
Particular requirements for walk -behind and hand -held lawn trimmers and lawn edge 
trimmers  (89 pages, in English)   
6. Description of content:  This International Standard deals with the safety of electric 
powered walk -behind and hand -held lawn trimmers and lawn edge trimmers, with cutting 
element(s) of non -metallic filamen t line or freely pivoting non -metallic cutter(s), with a 
kinetic energy of not more than 10 J each, used by a standing operator for cutting grass, 
their rated voltage not being not more than 250 V for a.c. or 50 V d.c.  
In this standard, hand -held and walk -behind lawn trimmers and lawn edge trimmers are 
referred to collectively as trimmer(s).  
So far as is practicable, this standard deals with the common hazards presented by 
trimmers which are encountered by all persons in the normal use and reasonably 
forese eable misuse of the trimmers.  
NOTE 101 Attention is drawn to the fact that in many countries additional requirements 
are specified by the national health authorities, the national authorities responsible for the 
protection of labour, the national water sup ply authorities.  
This standard does not apply to  
- scissor type or lawn trimmers and lawn edge trimmers with cutting means other 
than those described above;  G/TBT/N/BWA/60  
 
- 2 - 
 
  - self-propelled lawn trimmers or lawn edge trimmers;  
- lawn trimmers or lawn edge trimmers which do not have a distance of at least 600 
mm between the cutting means control and the cutting head;  
- battery -powered trimmers fitted with batteries that have to be removed for 
charging.  
NOTE 102 Requirements for tools with this type of battery can be found in Annexe s K and 
L of IEC 60745 -1. 
EMC and environmental aspects, except noise, have not been considered in this standard.  
NOTE 103 The method of calculating the kinetic energy for the purposes of this standard is 
given in 22.103.  
7. Objective and rationale , inclu ding the nature of urgent problems where applicable: 
Prevention of deceptive practices and consumer protection ; Quality requirements  
8. Relevant documents:  This clause of Part 1 is applicable except as follows.
