AS NZS 62841.2.17:2018 pdf free.Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery——Safety Part 2.17: Particular requirements for hand-held routers.
Type 2 routers shall have at least one handle and an additional handle or grasping surface to allow the operation of the tool with two hands. The motor housing and/or parts of the base that assist in guiding the router in use may be considered as a grasping surface, if identified as such in accordance with 8.14.2 b) 6).
Compliance is checked by inspection.
19.4.101 PreventIon of Inadvertent contact
The handles shall be so shaped or located as to minimise the risk of inadvertent contact of the user’s hand with the rotary cutting bit and the collet.
For type I routers, a removable cover for the purpose of changing the accessory which is provided to meet the requirements of 19.4.101 may be removable without the aid of a tool.
For handle(s), inadvertent contact of the user’s hand is considered to be prevented if there is sufficient distance between a defined measuring point on the handle surface and the rotary cutting bit and the collet.
Compliance is checked as follows:
A test pin with a diameter of the largest collet size is mounted to the tool. A mark is applied around the test pin (10 ± 1) mm from the collet. The distance between the defined measuring point and the mark on the test pin shall be at least 120 mm. The measurement shall be carried out as a chain distance. See Figure 101.
With the base set to maximum depth of cut, to establish the measuring point on the handle(s), follow the outlined procedure below.
a) Establish the closest (A) and the most distant (B) points from the plane of the base on the handle. Equidistant between points (A) and (B), draw the horizontal intersecting line on the plane parallel with the base and the surface of the handle.
b) The point on the intersecting line of the handle surface with the largest radial distance from the centreline of the spindle is the defined measuring point.
For a motor housing and/or parts of the base used as a grasping surface, inadvertent contact of the user’s hand is considered to be prevented by a barrier located between the grasping surface and the rotary cutting bit, see Figure 102. The barrier shall have a height x of at least 6 mm. A dust collecting system may be part of this barrier.
Alternatively to a barrier, for a motor housing and/or parts of the base used as a grasping surface in a type I router with an open portion(s) above the base, inadvertent contact of the user’s hand is also considered to be prevented if either
— the rotary cutting bit and the collet are not accessible above the base by means of the test probe B of IEC 61032:1997 with a force not exceeding 5 N:
or
— there is a minimum distance of 60 mm between
• a point located 40 mm above the lower edge of the grasping surface area in accordance with 8.14.2 b) 6) along its centreline; and
• any point on the edge of any open portion (see Figure 103).
Compliance is checked by manual test using test probe B of IEC 61032:1997 and by measurement. No covers are removed for the manual test. The 60 mm measurement is carried out as a chain distance.AS NZS 62841.2.17 pdf download.
