CSA/ANSI C22.2 No. 19085-8:21

1 Scope This document gives the safety requirements and measures for stationary calibrating and sanding machines, with an integrated feed and one or more sanding belt units positioned above and/or below the work piece level, with manual or automatic loading and/or unloading, hereinafter referred to as “machines”. It deals with all significant hazards, hazardous situations and events as listed in Clause 4, relevant to the machines, when operated, adjusted and maintained as intended and under the conditions foreseen by the manufacturer, including reasonably foreseeable misuse. Also, transport, assembly, dismantling, disabling and scrapping phases have been taken into account. NOTE 1 For relevant but not significant hazards, e.g. sharp edges of the machine frame, see ISO 12100:2010. It is also applicable to machines fitted with one or more of the following devices/additional working units, whose hazards have been dealt with: — transversal sanding unit; — cleaning brushing unit; — satining roller unit; — disk brushing unit; — texturing brushing roller unit; — texturing brushing belt unit; — cutterblock unit; — texturing band saw unit; — spiked roller unit; — antistatic bars; — conveyor directly controlled by the machine; — additional work piece vacuum clamping device. The machines are designed to calibrate and/or sand work pieces, in shape of panels or beams, consisting of: a) solid wood; b) material with similar physical characteristics to wood (see ISO 19085-1:2017, 3.2); c) gypsum boards, gypsum bounded fibreboards; d) composite materials with core consisting of e.g. polyurethane or mineral material; e) composite boards made from the materials listed above; f) all materials listed above, also already lacquered. This document does not deal with hazards related to: — specific devices other than those listed above; — access through in-feed and out-feed openings of machines with a work piece height capacity greater than 550 mm; — systems for automatic loading and/or unloading of the work piece to/from a single machine; NOTE 2 Loading the machine manually includes manually placing the work piece onto a conveyor directly controlled by the machine. Unloading the machine manually includes manually removing the work piece from a conveyor directly controlled by the machine. — interfacing of the machine with any other machine. It is not applicable to machines intended for use in potentially explosive atmosphere and to machines manufactured prior to the date of its publication. 1DV Modify Clause 1 by adding the following to the first paragraph: This Standard applies to calibrating and sanding machines that are intended to be installed and used in accordance with the National Electrical Code (NFPA 70) in the United States and the Canadian Electrical Code, Part I (CSA C22.1) in Canada. In Canada, general requirements applicable to these machines are provided in CSA C22.2 No. 0.
