This European Standard applies to castors and wheels
21、 which may include braking and/or locking devices, specifically for manually propelled use in an institutional environment. This includes for example, shops, restaurants, hotels, educational buildings and hospitals. 2 Normative references This European Standard incorporates by dated or undated refer
22、ence, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply only to this European Standard only when inco

24、e purpose of this European Standard, definitions and recommended symbols of EN 12526:1998 apply. 4 Dimensions and classification The characteristics of a castor are: fixing system (4.1); offset (4.2); wheel (4.3); load capacity (4.4). 4.1 Fixing system The fixing system includes top plate, solid ste
25、m and single bolt hole. 4.1.1 Top plate Top plates are identified by classification and include rectangular and square plates with four fixing holes. The design of the outer profile of the top plates is left to the manufacturer, provided that it is inscribed in a rectangle as provided in Tables 1 an
26、d 2 by sizes A and B of Figure 1 and A and A of Figure 2 which is the maximum acceptable size. The holes may be oblong and form slots, provided the width of the slots is suitable for bolts of diameter (G1) as in Tables 1 and 2. 4.1.1.1 Rectangular top plates Dimensions and classification of rectangu
27、lar top plates are detailed in Table 1 and illustrated in Figure 1. 4.1.1.2 Square top plates Dimensions and classification of square top plates are detailed in Table 2 and illustrated in Figure 2.
