DIN EN 16948:2017-09 EN 16948:2017 (E) 4 1 Scope This
24、 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 that are an integral part
25、 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 locking device device m
26、ounted 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 drawers” 3.2 locking m
27、echanism 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 effects or animated e
28、ffects 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 notes, or have flashin
29、g 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) require one action and
30、not release the locking mechanism when tested in accordance with 5.5.2; or DIN EN 16948:2017-09 EN 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 carried out and maintai
31、ned 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; or d) require th
32、e 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 disengaged. Howeve
33、r, 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 concerning the ch
34、ild 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 mechanism. The n
35、umber 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 disengage the lock
36、ing 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 mechanism in the first 5
37、 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 locking mechanism; b)
38、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 the child failed t
39、o 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 succeeded in dis
40、engaging the locking mechanism in the second 5 min, i.e. if the result is a failure. DIN EN 16948:2017-09 EN 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 test as soo
41、n 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 laid down in

46、 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 s
47、hall 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 with the locking device, the manufacturer shall ensure that they are suitable for the
48、 recommended material(s). If fixings are not provided, there shall be clear guidance on the type of fixings to be used with the device (see 4.6). When tested according to 5.5.1 and 5.5.4, none of the tested items or any part of the items shall be broken or have any visible cracks or permanent deform
49、ation or disengage. All devices shall be fully functional during and after the tests. For devices that are intended to re-engage automatically the automatic re-engagement function shall still operate after completion of the tests. For all locking devices when the product is mounted in accordance with the manufacturers instructions, the maximum gap into which a child could insert its fingers shall not exceed 30 mm for a depth o
