Abstract（描述）

　　ISO 8317:2015 specifies performance requirements and test methods for reclosable packages designated as resistant to opening by children.
　　Acceptance criteria are given for the packages when tested by specified methods. These methods not only provide a measure of the effectiveness of the packaging in restricting access by children, but also cover the accessibility to the contents by adults.
　　ISO 8317:2015 is applicable to reclosable packages for any product intended to be exposed or removed from the packaging in normal use.
　　ISO 8317:2015 is intended for type approval only and is not intended for quality assurance purposes.

　　This third edition cancels and replaces the second edition (ISO 8317:2003), which has been technically revised. It also incorporates the Corrigenda, ISO 8317:2003/Corr 1:2005.（标准区别）
　　In addition to a number of editorial revisions, the following technical revisions have been made with respect to the previous edition:
　　— introduction revised to remove historical discussion;
　　— definitions added for mechanical testing, mechanical test data, liner, essential characteristics, and minor modifications (2.6 to 2.10)
　　— former Clauses 3 and 4 consolidated into new Clause 3 and subsequent clauses renumbered;
　　— requirements in previous edition 3.1, 3.2 and 4.2 not part of the testing, have been relocated and are now informative. These are now included in the Introduction;
　　— introduction need to consider essential characteristics for a series of similar packaging (3.1.1);

　　— added new subclause on additions to a series and minor modifications (3.1.2.5);
　　— reference made to ISO 13127 (Introduction and 3.1.2.5);
　　— charts for sequential testing updated to correct errors (Figures 1 and 2);
　　— need to disable all (or any) incorporated tamper evident features before testing added (4.3);
　　— use of torque meter added for sample preparation of packages with torque dependent closures (4.3);
　　— deleted the limit (35 %) for the percentage of child tests administered by an individual tester (4.4.3);
　　— deleted the limit for number (30) of adults obtained from and tested at any one site, and number (35) of adult tests administered by an individual tester (4.5.2).
