AS/NZS 60745.2.19:2011 PDF – Hand-held motor-operated electric tools—Safety Part 2.19: Particular requirements for jointers
One sample of the tool is to be conditioned by cycling the guard from the fully closed position to the maximum open working position and then releasing for 50 000 cycles at a rate not less than 10 cycles per minute. Following the cycling, the tool is oriented with the weight of the tool in a direction causing the guard to open. The disc cutter shall not be accessible to a straight edge applied perpendicular to the disc cutter. The sample or a second sample at the manufacturers option is to then be conditioned by making 50 plunge cuts into soft wood that has been stored indoors for 72 h prior to the sawing. The tool is then conditioned for 24 h in a relative humidity of (90 ) % and at a temperature of (32 ± 2) °C.? The tool need not be conditioned by wood cutting if the accumulation of saw dust will not affect the closure of the guard. Following conditioning, the guard is to be operated through one complete cycle and the tool is oriented with the weight of the tool in a direction causing the guard to open. The disc cutter shall not be accessible to a straight edge applied perpendicular to the disc cutter.
20 Mechanical strength
This clause of Part 1 is applicable, except as follows: 20.3 This clause of Part 1 is applicable for all parts except the disc cutter and guard. The disc cutter and guard shall be evaluated in accordance with 20.1 01 .
20.1 01 A jointer guard shall have adequate mechanical strength. Compliance is checked by the following tests, for which a separate sample may be used. A jointer retracting guard shall withstand the tool being dropped one time from a height of 1 m onto a concrete surface. The tool shall be oriented to achieve the most adverse affect on the guard. Following the impact, the guard is to be operated through one complete cycle and the tool is then oriented with the weight of the tool in a direction causing the guard to open. The disc cutter shall not be accessible to a straight edge applied perpendicular to the disc cutter.
