They shall be healthy, with rio evident physical handicap, which may affect manual dexterity. They shall not have taken part in more than one previous test and, in that test, a device of a different type with locking arrangements based on a different principle shall have been involved. If a child is used on more than one test panel, it Is desirable that there should be at least one week between the tests.
It Is preferable for only one test to be carried out in one testing session, because there may be a statistically significant difference in the test results between the first and second windows locking device test tried.
5.4.4.3 Test location
The children shall perform the test in any place with which they are familiar or relaxed, for example, in their usual school or nursery, but they shall be removed from the general school population and separated form extraneous distraction.
5.4.4.4 Procedure
The test may be carried out using the full test panel of 200 children or by a sequential procedure. If the latter is used, the number of children tested will depend on the results obtained (see 4.1.2.3). When testing sequentially, the age and sex constraints specified in 5.4.4.2 shall be adhered to.
The chikiren shall be tested alone, each one being monitored by one supervisor. The child may adopt any attitude or position he or she finds convenient. Should a child wander off during the test, action by the supervisor shall be limited to leading the child back to its place and requesting that he or she continue the test, without any additional instruction being given concerning the disengaging of the locking device; this fact shall be included in the report.
Each child shall be placed in front of the child panel test rig with a mounted locking device with the request that it be disengaged by whatever means the child wishes to use; in order to achieve this, 5 mm shall be allowed. No attempts shall be made to stop a child using its teeth or any other method of disengaging the device. No tools or implements shall be accessible which might be used by the child.
Any child failing to disengage the locking device in 5 mm shaH then watch a device being disengaged and engaged by the supervisor in lull view, without emphasis being placed on the actions of disengaging and without any verbal instruction. The child shall then have a further 5 mm to disengage the device.
At the conclusion of each test, the children shall be warned not to play with these types of locking devices, or attempt to open real windows or balcony doors.
5.4.4.5 Expression of results
After each period of 5 mm, it shall be recorded whether a child fails to disengage the locking device: if the child succeeds, it shall be recorded whether this was before or after a demonstration. It shall also be recorded whether teeth (or any other means) were used to disengage the device.
