It is a revision of BS3936-2:1978 which is withdrawn. The revision covers the requirem
9、ents of buyers and sellers more fully so that the quality of plants may be improved and includes all types of roses irrespective of the method of propagation or origin. It has been assumed in the drafting of this British Standard that the execution of its provisions is entrusted to appropriately qua
10、lified and experienced people. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of

12、-1999 1 1 Scope This Part of BS3936 specifies requirements for rose plants that are sold for transplanting and growth for amenity purposes. The following types of rose plants (which may be in pots or tubs for outdoor use) are specified, irrespective of the method of propagation: a) bush and shrub ro
13、ses; b) climbing, rambler and pillar roses; c) standard, half-standard and weeping standard roses; d) dwarf roses; e) miniature roses; f) low-growing floribunda roses (patio roses); g) ground cover roses. NOTEBecause of the natural variability of the plants and because the list of available varietie
14、s is constantly changing, this British Standard cannot include a list of varieties corresponding to each type. Roses grown purely for indoor use, e.g.houseplants, are outside the scope of this standard. 2 Definitions For the purposes of this Part of BS3936 the following definitions apply. 2.1 countr

33、origin is the UK.

The accuracy of the
35、claim is therefore solely the responsibility of the person making the claim. Such a declaration is not to be confused with third party certification of conformity, which may also be desirable.5 blankBSI 389 Chiswick High Road London W4 4AL | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
