TM: 016 Date: 16/8/11 Author: S Clark Title: Performance Testing of Toasters

1.0 Scope

This testing applies to all toasters designed for domestic use. It applies to all market sectors and to all format toasters in metal and plastic construction.

This test method applies to the performance of the toaster and does not cover the endurance testing which is covered by a separate test method (TM0015)

2.0 Method

2.1 Power Check

To measure the correct power of a toaster, a calibrated power analyser is required. If this is not available then separate measurements of voltage and power can be used. As toasters will be predominantly resistive with very little reactive power, then wattage can be calculated by measuring current and calculating power. The power of a toaster will typically vary considerably from cold to hot so when measuring power this should be done in when the power has stabilised.

2.2 Toasting Tests

For all tests the toaster shall be used to its maximum capacity i.e. a 2 slice toaster should be tested with 2 slices of bread; a 4 slice toaster should be tested with 4 slices.

For all combinations, the toasting is tested consecutively for three operations with a 10s maximum gap between each. The results shall be laid out, clearly marked and photographed.

The following tests are to be carried out at BOTH maximum and minimum supply voltages:

1. Domestic supermarket thin white fresh bread at minimum, mid and maximum browning settings 2. Domestic supermarket medium white fresh bread at minimum, mid and maximum browning settings 3. Domestic supermarket thick white fresh bread at minimum, mid and maximum browning settings 4. Domestic supermarket medium brown fresh bread at minimum, mid and maximum browning settings 5. If the toaster has a frozen button then use domestic supermarket medium FROZEN white bread with the toaster set at medium and the ‘frozen’ button pressed. If the toaster has a frozen setting on the browning control then this is used. TM016 Page 2 of 2 Issue A 3.0 Acceptance Criteria

3.1 Power check

Measured power should be within 10% of rated for all price points.

3.2 Toasting checks

All of the tests are subjective and so the ultimate acceptance or otherwise will be given by a decision of the HoMedics Product Manager:

1. .For all toast types and at both voltage, there must be settings that provide a range of toast colours from light brown to dark brown. 2. For all tests the third slices of toast must be the same colour as the first. 3. For frozen bread the browning should be the same as the equivalent fresh bread. 4. The toast must show even colour over 80% of the area. 5. Both sides of the toast shall appear identical.
