It is a revision of BS3936-2:1978 which is withdrawn.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

11、 pages This document comprises a front cover, an inside front cover, pages i and ii, pages1 to 4 and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on theinside front cover.BS3936-2:1990 BSI 03

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.

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 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
