18、es. 1.2 These requirements do not cover products that exclusively use forms of batteries other than lithium button or coin cells. 1.3 These requirements apply to consumer products containing lithium button or coin cells. They do not apply to products that by virtue of their dedicated purpose and ins
19、tructions are not intended to be used in locations where they may be accessed by children, such as products for dedicated professional use or commercial use in locations where children are not normally or typically present. 1.4 These requirements are intended to supplement other safety requirements
20、for products that incorporate button or coin cell batteries, and are not intended to supersede specic requirements that are incorporated into other safety standards to mitigate physiological hazards from button or coin cells. 2 Units of Measurement 2 effective November 10, 2015 2.1 Values stated wit

26、tton/coin cell to be contacted by Test Probe 11 of the Standard for Protection of Persons and Equipment by Enclosures Probes for Verication, IEC 61032 when applied as described in 5.3. 5.3 The probe shall be applied to any depth that the opening will permit and shall be rotated or angled before, dur
27、ing, and after insertion through the opening to any position that is necessary to examine the enclosure. The probe shall be used as a measuring instrument to judge the accessibility provided by an opening, and not as an instrument to judge the strength of a material. The probe shall be applied with
28、the minimum force necessary to determine accessibility. 5.4 During the examination of a product to determine whether it complies with the requirements in 5.3, a part of the enclosure that may be opened or removed by the user, either without using a tool or with less effort than two independent and s
29、imultaneous movements by hand, is to be opened or removed. 5.5 Products that locate removable or replaceable button/coin cell batteries inside a battery compartment shall be designed to prevent children from removing the battery by one of the following methods in (a) or (b) below.

31、e used to secure the door or cover providing access to a battery compartment, the fasteners shall be captive to the door, cover, or device. Exception: This requirement does not apply to large panel doors on large devices which are not likely to be discarded or left off the equipment. 5.7 Products th
32、at incorporate button/coin cells that are not intended for user removal or replacement shall effectively prevent removal of the battery by the user or children.
