EN 16293-2020 pdf download.Packaging – Glass Packaging-Deep BVS finishes for still Wines.
This EN 16293 specifies dimensions of a series of deep screw finishes for the closure of wines with a COz content below 1.2 g per litre.
NOTE Carbonation  1,2 g/l C02 requires a suitable container and closure agreed between the glass maker, closure maker and packer/filler.

3.1
deep BVS finish
neck finish designed to receive a screw cap equipped with a tamper evident skirt
4 Designation
The finish can be defined successively by its name (BVS), the diameter (In mm). the type (H) and the height of the closure (in mm). for example BVS 28 H 44, BVS 30 H 60.
5 Recommendations
Container verticality should be controlled as specified in Clause 12 Control of bottle and neck verticality.
During capping, when changing between different batches of bottles conforming to this document or different batches of caps. it is necessary to verify the setting of the capping equipment.
6 Constructions and dimensions of deep BVS finishes
The constructions of deep BVS finishes shall be as given in the following figures:
— Figure 1: Constructions and dimensions
— FIgure 2: OptIonal finIsh with additional support bead
— FIgure 3: OptIonal take-out groove
The dimensions of deep BVS finishes shall be as given In the following tables:
— Table 1 – Dimensions for finishes type BVS
— Table4-DlmenslonsY and X for finishes type BVs
Detail X: the 3° mm. 15° max. angle and the associated geometry are essential to achieve proper capping application. During capping when changing between different batches of bottles conforming to this document or different batches of caps, it is necessary to ver1t’ the setting of the capping equipment.
The area of the finish in contact with the crimped metal of the applied cap shall be as smooth as possible. The presence of glass surface coatings shall be kept to a minimum according to best industrial practice, for example see Reference [4j.
10 Construction of the neck
The constructions of the neck shall be as shown in Figure 7.
12 Control of bottle and neck verticality
Bottles with deep BVS finishes shall respect industrial standards or practice for verticality as for example Reference [3].
Additionally, because of the special closure application on this finish, further controls for bent necksN shall be made according to the values in Figure 9 to achieve optimum performance.EN 16293-2020 pdf download.
