controls having non-electrical outlets This standard does not apply to time-delay switches (TDS) within the scope of IEC 60669-2-3 1) Throughout this standard, the word “timers” means timers and time switches, unless the type is specifically mentioned Devices which only indicate time or passage of time are not included This standard does not apply to multi-functional controls having an integrated timing function which is not capable of being tested as a separate timing device 1.1.1 This standard applies to the inherent safety, to the operating characteristics where such are associated with equipment protection and to the testing of automatic electrical control devices used in appliances and other apparatus, electrical and non-electrical, for household and similar purposes, but also extended to industrial purposes when no dedicated product standards exist, such as that for central heating, air conditioning, process heating, etc Timers for equipment not intended for normal household use, but which nevertheless may be used by the public, such as equipment intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard This standard is also applicable to timers for appliances within the scope of IEC 60335-1 This standard does not apply to timers designed exclusively for industrial applications Throughout this standard, the word "equipment" means "appliance and equipment" 1.1.2 This standard applies to automatic electrical control devices, mechanically, electromechanically, electrically or electronically operated,

is reduced by the number of cycles carried out during those tests If a clutch is used during the tests of 17.10 to 17.13 inclusive, care should be taken to ensure that it does not fail due to the acceleration If it fails or is considered liable to fail, the speeds of actuation shall be as specified, but rest periods shall be introduced between cycles to allow the heat dissipation which would occur during normal use Additional subclause: 17.1.3.101 At the end of each cycle, for timers only, an appropriate actuation shall be performed to initiate the next cycle If a timer or time switch has different programs, that program which utilizes the maximum number of contact operations shall be chosen, unless a timer with a special test program has been submitted by the manufacturer If the program does not cause all the contacts to be operated, the test shall be repeated on a new set or sets of samples operating on other programs to ensure that all contacts are tested These extra samples need not be tested where the design is such that the results can be reasonably predicted from the result of the first set of samples, as could be done if the design of all contacts were identical BS EN 60730-2-7:2010 EN 60730-2-7:2010 (E) – 12 – If a timer with a special test program is used, it shall be so designed that it is possible, by carrying out the special program, to reasonably predict the test results for all specific application programs of the timer In-line cord, free-standing and independently mounted controls shall be tested as follows – For timers declared for resistive load, the number of cycles of contact operation for each contact of the time switch shall be A = 000 The number of cycles of actuation (M) for each manual action of the time switch shall be M = 500 (inducing 500 cycles of contact operation) – For timers declared for resistive or inductive load, the number of cycles of contact operation for each contact so rated shall be 000, consisting of a first number of cycles A = 500, to be tested with a substantially resistive load as specified in Table 17.2-1, ˆText deleted‰ followed by a second number of cycles, A = 500, which shall be conducted at the conditions specified in Table 17.2-1 ˆText deleted‰ , for resistive or inductive load The number of cycles of actuation (M) for each manual action of these timers shall be M = 500 (inducing 500 cycles of contact operation, tested under resistive load conditions) – If the timer requires an external electrical or mechanical signal to move it from a rest position this shall be simulated, if necessary in the manner declared by the manufacturer – For timers and time switches with Type actions, any electrically driven prime mover shall for at least 50 % of the test, be connected to a supply of 0,9 V R , all other loads and connections remaining as in 17.7 – For timers and time switches with Type actions, if there is any failure attributable to the acceleration (such as the excessive use of a clutch), then the test is held to be invalid and should be repeated in another manner 17.2 Electrical conditions for the tests Table 17.2-1 – Electrical conditions for the
