It amends and supplements EN 957-1. The r
21、equirements of this specific standard take priority over those in the general standard. 1 Scope This part of EN 957 specifies safety requirements for rowing machines in addition to the general safety requirements of EN 957-1 and should be read in conjunction with it. This part of EN 957 is applicabl
22、e to stationary training equipment type rowing machines (type 7), hereinafter referred to as rowing machines, within classes S and H, and class A regarding accuracy. If accessories are provided with the rowing machine for the performance of additional exercises these are subject to the requirements
23、of EN 957-1 and any other specific requirements of the appropriate part of this standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the p

29、 construction 5.2.1 Squeeze, shear and reciprocating points within the accessible area The distance between movable parts and adjacent movable or rigid parts shall be at least 25 mm if relevant for fingers only, otherwise it shall be at least 60 mm. Required stops are excluded (if the user is not pu
30、t at risk). Accessible stops shall each have a minimum surface of 400 mm 2 . Stops which compress shall each produce a surface of 400 mm 2 when compressed with a pressure of 90 N/cm 2 . The 60 mm does not apply when the squeeze points remain within the users field of vision over the full range of mo
31、vement during use (see Figure 4). If the distance between movable parts and adjacent rigid parts does not change during the movement, the test fingers of 6.2 shall not become trapped.Page 6 EN 957-7:1998 BSI 01-1999 5.2.2 Transmission elements and rotating parts Transmission elements, fans and flywh
32、eels shall be protected so that, when tested in accordance with 6.2, the test finger cannot be trapped. 5.2.3 Temperature rise When tested in accordance with 6.4, accessible parts of the rowing machine shall not have a temperature greater than 658C. 5.2.4 Seats When tested in accordance with 6.3 and
33、 6.1.4, the seat shall not derail. 5.3 Intrinsic loading When tested in accordance with 6.5: with 250 kg for class H; and with 300 kg for class S; each piece of equipment shall withstand the test force without being deformed for more than f = 1/100 for a simply supported beam and f = 1/150 for a can
34、tilever beam (see Figure 5). After the test all parts of the equipment shall function according to the manufacturers instructions for use. The seat wheels or rollers should not have excessive play and shall rotate freely. 5.4 Handles In rowing machines where the handle is connected to the machine by
35、 a flexible member (rope belts or chains), the mass of the handle without a flexible member shall not exceed 600 g. Test in accordance with 6.1.5. 5.5 Foot supports and foot straps For classes S and H, provisions shall be made for fastening the foot (foot straps); for class S, the foot support or fo
36、ot strap shall be adjustable for different foot sizes. Test in accordance with 6.1.4. When tested in accordance with 6.6.1, each foot strap shall withstand: in class H: 500 N; in class S: 1 000 N; without breakage. When tested in accordance with 6.6.2, each foot support shall withstand a test load o
37、f 1 000 N without breakage. 5.6 Endurance test When tested in accordance with 6.7, the rowing machine shall withstand: 12 000 cycles for class H; and 100 000 cycles for class S. After the test the rowing machine shall be capable of functioning according to the manufacturers instructions for correct
38、use and shall not show any signs of damage, e.g. oil leakage. 5.7 Stability When tested according to 6.8, the base of the rowing machine shall not lift more than 10 mm. 5.8 Additional requirement for class A The variation of the indicated or determined power P from the power input shall not exceed 5

Test in accordance with 6.9. 6 Test methods 6.1 General 6.1.1 Dimensional check 6.1.2 Visual examination 6.1.3 Tactile examination 6.1.4 Performance test 6.1.5 Weighing test 6.2 Testing of squeeze, shear and reciprocating points within the accessible area and transmis
40、sion elements and rotating parts Apparatus: test finger probe B in accordance with EN 71-1 for class H; and test finger in accordance with EN 957-1:1996, 6.5, for class S. Approach the test fingers from all sides to all moving parts. Determine whether the test finger is trapped. 6.3 Testing of seats
41、 Apply a test force of 100 N for 1 min to all directions of the seat. Check if the seat always remains attached to the rail. 6.4 Testing of temperature rise Apparatus: contact thermometer with an accuracy of 18C. Operate the rowing machine for 20 min at the following values: a) for speed-independent
42、 equipment: 25 complete strokes per min; 350 N measured at one or both handles combined; 60 % of the whole movement; b) for speed-dependent equipment: 350 N over 60 % of the movement at the appropriate stroke rate. The power of 350 N is the average power produced over one complete stroke.Page 7 EN 9

Apply a test load F of 250 kg (class H); and 300 kg (class
44、S); to the seat for 5 min, see Figure 5. Remove the load and determine the reference dimensions f according to Figure 5. The feet of the equipment shall not be fixed to the floor during the test. 6.6 Testing of foot supports and foot straps 6.6.1 Apply the test force at the centre of the foot strap
45、at right angles to the foot supports for 1 min. 6.6.2 Apply the test force of 1 000 N to the foot support by using a test device in accordance with Figure 6 for 1 min. a) simply supported beam b) cantilever beam Figure 5 Permanent deformation testPage 8 EN 957-7:1998 BSI 01-1999 1 start of a stroke

47、 EN 547-3, with a moving load of 60 kg placed on the seat. For speed-dependent machines carry out the test at a speed which produces a force of 200 N at the handles. Perform the endurance test as follows: a) for class H: 12 000 cycles working for 15 min and rest time 15 min and continuing the same p
48、attern until the test is complete; b) for class S: 100 000 cycles working for 10 h, cool down to room temperature, then continue for a further 10 h and continue until the test is complete. Check after the test whether the rowing machine is capable of functioning according to the manufacturers instru
49、ctions for correct use, or if there are any signs of damage. 6.8 Testing of stability A test person weighing (100 5) kg, height (1 750 50) mm shall sit on the rowing machine in a normal exercise position and operate the rowing machine as mentioned in the manual: at 35 strokes/min at minimum resistance for speed-independent machines; and at 35 strokes/min for speed-dependent machines.
