3.10
junction line
the intersection of the seat and the backrest
Note The method to determine the junction line can be found in cl. 4.2
2 Modification to Clause 4, General test conditions
Replace the text of 4.1 with the following:
The tests are designed to be applied to a high chair that is fully assembled according to manufacturer’s
instructions and ready for use.
If the product can be converted to other products not falling within the scope on this standard (e.g. table and
small chair, adult chair, swings, booster seats, etc.), these configurations shall not be tested according to this
standard.
The tests shall be carried out in indoor ambient condition with a temperature between 15° and 25° C. If the
temperature lies outside this range, its maximum and minimum shall be recorded in the test report.
The high chair shall be tested as delivered. If the high chair is a knock-down type, it shall be assembled
according to the instructions supplied with it. If the instructions allow for different adjustments or configurations
of components (e.g. inclination of the backrest, height of the seat, position of the tray, position of
castors/wheels, etc.), the most onerous combination shall be used for each test.
Knock-down fittings shall be tightened before testing. Further re-tightening shall not take place unless this is
specifically required by the manufacturer’s instructions.

Add new clause 4.2, as follows:
4.2 Determination of the junction line
The junction line is shown in Figure 1 below.

LL junction line
Figure 1 — Junction line
When the seat unit is in the form of a hammock, then a theoretical junction line, “LL”, is determined as shown
in Figure 2.
