27、017 (E) 4 1 Scope This European Standard specifies requirements and test methods for locking devices fitted by consumers in a domestic environment for cupboards and drawers for restricting access by young children. Child resistant locking devices only intended to be installed by professionals or tha
28、t are an integral part of the cupboard and drawer system are beyond the scope of this standard. 2 Normative references Not applicable. 3 Terms and Definitions For the purposes of this document, the following terms and definitions apply. 3.1 child protective locking device for cupboards and drawers l
29、ocking device device mounted on cupboards and drawers intended to make it difficult for young children to access the contents of the cupboard/drawer Note 1 to entry: In the remainder of the document the short expression “locking device” is used for “child protective locking device for cupboards and
30、drawers” 3.2 locking mechanism part of the locking device which prevents opening of the cupboard or drawer 3.3 child appealing locking device locking device that resembles by any means another object commonly recognized as appealing to or intended for use by young children, or has entertaining audio
31、 effects or animated effects Note 1 to entry: This includes, but is not limited to locking devices the shape of which resembles cartoon characters, toys, guns, watches, telephones, musical instruments, vehicles, human body or parts of the human body, animals, food or beverages, or that play musical
32、notes, or have flashing lights or moving objects or other entertaining features. 4 Requirements 4.1 Child appeal The locking device shall not be child appealing. 4.2 Child protective function 4.2.1 General The locking mechanism shall be resistant to operation by young children. It shall either: a) r
33、equire one action and not release the locking mechanism when tested in accordance with 5.5.2; or BS EN 16948:2017EN 16948:2017 (E) 5 b) require at least two consecutive actions to release the locking mechanism, the operation of the second action being dependent on the first action having been carrie
34、d out and maintained and not release the locking mechanism when tested in accordance with 5.5.3; or c) require at least two separate but simultaneous actions to release the locking mechanism operating on different principles and not release the locking mechanism when tested in accordance with 5.5.3;
35、 or d) require the use of a specifically designed removable device or removable tool (e.g. a key or a magnet); or e) comply with the child panel test requirements in 4.2.2. Ideally, the locking mechanism would automatically re-engage when closing the cupboard or drawer after having been completely d
36、isengaged. However, at this point in time this is not a requirement. It may become a requirement in future. In b) maintaining or removing the first action cannot mean that the locking mechanism remains in the partially unlocked position without continued intervention of the user. 4.2.2 Requirements
37、concerning the child panel test 4.2.2.1 General The locking mechanism shall comply with either 4.2.2.2 or 4.2.2.3. The child panel test is required only in case option 4.2.1 e) is chosen. The minimum number of children required in the sequential test depends on how many children can open the locking
38、 mechanism. The number to pass a locking device can be as low as 30. 4.2.2.2 Test panel of 200 children If the full test panel of 200 children is used when testing in accordance with 5.4, the following requirements shall be met: a) at least 85 % of the children in the test panel shall be unable to d
39、isengage the locking mechanism within the first 5 min without a demonstration; and b) at least 80 % of the children in the test panel shall be unable to disengage the locking mechanism within another 5 min after a demonstration has been given to those children unable to disengage the locking mechani
40、sm in the first 5 min. 4.2.2.3 Sequential test less than 200 children If the full test panel is not used when testing in accordance with 5.4, the result is obtained from completing Figure 1 and Figure 2 as follows: a) the result of the test is a failure if the child succeeds in disengaging the locki
41、ng mechanism; b) as each result is obtained, it shall be plotted on the appropriate chart by filling in a square as follows: 1) fill in a square immediately to the right of the previous result on Figure 1 if the child failed to disengage the locking mechanism in the first 5 min, and on Figure 2 if t
42、he child failed to disengage the locking mechanism in the second 5 min, i.e. if the result is a success; 2) fill in a square immediately above the previous result on Figure 1 and Figure 2 if the child succeeded in disengaging the locking mechanism in the first 5 min, or only on Figure 2 if the child
43、 succeeded in disengaging the locking mechanism in the second 5 min, i.e. if the result is a failure. BS EN 16948:2017EN 16948:2017 (E) 6 In the case of the first result to be plotted, the blanked out square is regarded as the “previous result”. The locking device shall be deemed to have: passed the
44、 test as soon as the trail of filled squares passes below limit line 1 on both Figure 1 and Figure 2; failed the test as soon as the trail of filled squares passes above limit line 2 on either Figure 1 or Figure 2. If neither occurs, the results shall be assessed in accordance with the requirements

49、sengage the locking mechanism and, where appropriate, to engage it properly, the method used by children to disengage it, etc. shall be recorded. 4.3 Mechanical function and structural integrity The locking device shall maintain its mechanical properties throughout its expected lifetime. The manufacturer shall indicate the type(s) of cupboards and drawers including the materials (e.g. glass, aluminium, PVC, wood) for which the locking device is or is not suitable. In particular, if fixings (e.g. screws) are provided
