ISO 16419:2013 pdf free.Cork一Visual anomalies of cork stoppers for still wines
ISO 16419 applies to both
一semi-elaborated natural cork stoppers and colmated natural cork stoppers at the definitive dimensions stage, and
一finished natural cork stoppers and colmated natural cork stoppers ready to use.
It describes the anomalies of cork stoppers that can be detected byvisual examination of the manufacturer or the end-user.
These anomalies, according to their size, can have functional or not functional consequences being able to alter, more or less, the cork stoppers’ sealing capacity.
On the basis of a common sampling example, this International Standard proposes for all these anomalies some specifications for stoppers.
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 633, Cork一Vocabulary
Other aspect irregularities are not considered as anomalies since they only affect the cork stoppers’ presentation and will be taken into account in the cork stoppers’ visual classification.
In the case of having more than one anomaly with functional consequence in the same cork stopper, only the most important will be considered (penalized).
Anomalies of natural corkwood stoppers and colmated natural cork stoppers for still wines
Both Table 1 and Table 2 present the anomalies in relation to the raw material and to the fabrication process respectively, being:
一columns 1 and 2 – The name and definition of the anomaly in accordance with ISO 633 (Vocabulary).
一columns 3 and 4 – The threshold relates to the size and/or the position of the anomaly to be considered in order to assess whether it is likely to have a functional or not functional consequence (if the threshold is not reached, the observed visual irregularity does not count as an anomaly).
一columns 5, 6, and 7 – The acceptance quality limit ([AQL) specifications according to the cork stoppers’ range.
These tables are considered for a working sample of 80 selected cork stoppers, which are considered a representative sample of a lot.
This value, which is given as an example, corresponds to day-to-day practices in the enterprises.ISO 16419 pdf download.
