The board shall be supported on resilient material and
34、 fixed by screws, clamps, air cylinders or the like to a test rig. For sabre saws: Cutting a vertical piece of chipboard (P2 in accordance with EN 312) 38 mm thick with a minimum length of 500 mm and a width of 600 mm. The board shall be supported on resilient material and fixed vertically by screws
35、, clamps, air cylinders or the like to a test rig. In all cases, the board excess end shall be 250 mm from the clamp and shall be readjusted at the beginning of each series of tests, which consists of five test cycles. Tool bit/settings New saw blade as specified for sawing chipboard. Pendulum syste
36、ms, if any, being set at maximum. For sabre saws, the guide plate shall be fitted. Feed force For jig saws: The horizontal feed force (force in direction of the cut) applied to the tool shall be 35 N 5 N. Excessive gripping force shall be avoided. The guide plate shall be in contact with the work pi
37、ece during the cut applying a force just great enough to ensure this. NOTE 1 Methods to determine the feed force are e.g. using a scale, applying a weight on a string parallel to the workpiece surface via a pulley. NOTE 2 Usually, the downward force in addition to the weight of the tool to keep the
38、guide plate of a jig saw in contact with the workpiece is between 50 N and 100 N. For sabre saws: The vertical feed force (force in direction of the cut) applied to the tool in addition to its weight shall be 40 N 5 N. The feed force shall be determined e.g. by means of a scale and shall be recorded
39、. Excessive gripping force shall be avoided. The guide plate shall be in contact with the work piece during the cut applying a force just great enough to ensure this. NOTE 3 Usually, the horizontal force to keep the guide plate of a sabre saw in contact with the workpiece is between 50 N and 100 N.
40、Test cycle Cutting a 30 mm wide strip across the 600 mm width of the chipboard. Measurement starts when the saw blade enters the chipboard and stops when the saw blade leaves the chipboard. 7 BS EN 60745-2-11:2010EN 60745-2-11:2010Table Z102 Test conditions for jig saws cutting sheet metal Orientati

The work piece shall be supported on resilient material and fixed by screws, clamps, air cylinders or the like to a test rig. The metal sheet excess shall be 80 mm from the
42、 clamped area and shall be readjusted at the beginning of each series of tests, which consists of five test cycles. Tool bit/settings New saw blade as specified for sawing mild steel. The pendulum system, if any, shall be in the “off” position. Feed force The horizontal feed force (force in directio
43、n of the cut) applied to the tool shall be 35 N 5 N. Excessive gripping force shall be avoided. The guide plate shall be in contact with the work piece during the cut applying a force just great enough to ensure this. NOTE 1 Methods to determine the feed force are e.g. using a scale, applying a weig
44、ht on a string parallel to the workpiece surface via a pulley. NOTE 2 Usually, the downward force in addition to the weight of the tool to keep the guide plate of a jig saw in contact with the workpiece is between 50 N and 100 N. Test cycle Cutting off an approximately 8 mm wide strip across the 100
45、 mm width of the metal sheet. Measurement starts when the saw blade enters the metal sheet and stops when the saw blade leaves the metal sheet. Table Z103 Test conditions for sabre saws cutting wooden beams Orientation Cutting a horizontal beam of construction wood such as fir with a cross section o
46、f 100 mm x 100 mm and minimum length of 500 mm. The beam shall be supported on resilient material and fixed by screws, clamps, air cylinders or the like to a test rig. In all cases, the beam excess end shall be 250 mm from the clamp and shall be readjusted at the beginning of each series of tests, w
47、hich consists of five test cycles. Tool bit/settings New saw blade as specified for sawing large wooden beams. The pendulum system, if any, being set at maximum. Feed force The vertical feed force (force in direction of the cut) applied to the tool in addition to its weight shall be 40 N 5 N. The fe
48、ed force shall be determined e.g. by means of a scale and shall be recorded. Excessive gripping force shall be avoided. The guide plate shall be in contact with the work piece during the cut applying a force just great enough to ensure this. NOTE Usually, the horizontal force to keep the guide plate
49、 of a sabre saw in contact with the workpiece is between 50 N and 100 N. Test cycle Cutting off a 30 mm thick slice. Measurement starts when the saw blade enters the wood and stops when the saw blade leaves the wood.
