test shall be carried out using the break point as determined in paragraph 3.1.1.1.

              3.1.1.3. A check shall be carried out at the beginning of each production run or following a change of colour.

              3.1.1.4. During the production run the check tests shall be carried out at the following minimum frequency:

Toughened-glass windscreens                         Toughened-glass panes     Treated laminated-glass windscreens
Ps  200: one break per production run              Pr  500: one per shift   0.1 per cent per type
Ps > 200: one break every four hours of production  Pr > 500 : two per shift

              3.1.1.5. A check shall be carried out at the end of the production run on one of the last  glazing manufactured.

              3.1.1.6. For Pr < 20, only one fragmentation test per production run shall be carried out.

              3.1.2. Results

               All results shall be recorded, including the results without permanent recording of the fragmentation pattern.

               In addition, a test with permanent recording of the fragmentation pattern shall be made once per shift, except for Pr ≤ 500. In this last case only one test with permanent recording of the fragmentation pattern shall be made per production run.

              3.2. Headform test

              3.2.1. Tests

               The check shall be carried out on test pieces corresponding to at least 0.5 per cent of the daily production of laminated-glass windscreens of one production line. A maximum of 15 windscreens per day shall be tested.

               The choice of test pieces shall be representative of the production of the various types of windscreen.

               As an alternative and with the agreement of the administrative service, these tests may be replaced by the 2,260 g ball test (see paragraph 3.3. below). Behaviour under head impact shall in any event be checked on at least two samples for each thickness class per year.

              3.2.2. Results

               All results shall be recorded.

              3.3. 2,260 g ball-impact test

              3.3.1. Tests

               The minimum frequency for the check shall be one complete test per month for each thickness class.

              3.3.2. Results

               All results shall be recorded.

              3.4. 227 g ball-impact test

              3.4.1. Tests

               The test pieces shall be cut from finished parts. However, for practical reasons, the tests may be carried out on finished products of parts of them.

               The check shall be carried out on a sampling corresponding to at least 0.5 per cent of the production of one shift with a maximum of ten samples per day.

              3.4.2. Results

               All results shall be recorded.

              3.5. Test of resistance to high temperature

              3.5.1. Tests

               The test pieces shall be cut from finished parts. However, for practical reasons, the tests may be carried out on finished products or parts of them. These shall be selected so that all interlayers are tested proportionately
