201.9.8.3.2 *Static forces due to loading from persons
Add, after the existing second paragraph the following note:
NOTE It might be necessary to support assemblies that are connected to the assembly under test but do not
require such a high safety factor, e.g. an assembly under test requires a TENSILE SAFETY FACTOR of 4 and the
assembly supporting it is designed with a lower TENSILE SAFETY FACTOR. Use of additional support should be
explained in the test report.
Annex AA – Particular guidance and rationale
AA.2 Rationale for particular clauses and subclauses
Subclause 201.1.1 – Scope
Add, at the end of the existing third sentence, the phrase: ", a weight of equal to or more than
40 kg and a body mass index (BMI) equal to or more than 17."

Add the following new rationales:
Definition 201.3.201 – ADULT
The body mass index is calculated by the following formula:
m
BMI=
l
Where:
m in kg
l in m
The body mass index (BMI) as an additional measure for the shape of the human body was
included in IEC 60601-2-52, since the physical size of some patients is indeed inside the
limits of the first version of IEC 60601-2 52 (exceeding 146 cm and 40 kg) but nevertheless
due to their particular atypical anatomy there might be a risk of being entrapped in the side
rails.
The body mass index (BMI) is a measure for the human body shape based on an individual's
mass and height. BMI provides a simple numeric measure of a person's thickness or thinness,
allowing health professionals to discuss overweight and underweight problems more
objectively with their PATIENTS.
For an explanation see also 201.1.1.
Subclause 201.4.2 – RISK MANAGEMENT PROCESS for ME EQUIPMENT or ME SYSTEMS
Possible HAZARDS may be: rolling over the SIDE RAIL, entrapment in MEDICAL BED extension and
HAZARDS related to the TRAPPING ZONES described in 201.9.2.2.

Subclause 201.9.101 – Protection against inadvertent PATIENT falls
Delete the existing fourth paragraph of this rationale.
