【国外标准】 Standard Guide for Writing a Specification for Flexible Barrier Rollstock Materials

5.1 Flexible barrier materials are universally used across industries and produced by a myriad of suppliers. They may be monolayer materials or complex composite structures. However, even with the diversity of material, there are still basic requirements that all flexible barrier materials should exhibit.5.2 Flexible barrier material requirements may be divided into two categories, initial material qualification, and routine production and receipt requirements to ensure the purchaser receives exactly what is ordered. While all requirements may be included in the written specification, initial qualification tests may only be needed prior to the first order. Routine production and receipt requirements should be adhered to on every order. Initial qualification requirements are indicated with each clause, where applicable.5.3 This guide provides an understanding of the requirements needed for the manufacture, purchase, and acceptance of flexible barrier materials. Appropriate test methods for compliance are also cited.NOTE 1: All test methods for a particular requirement may not be cited due to specific or unique circumstances. For additional guidance on applicable methods, refer to Guide F2097.5.4 The specification and its requirements should be mutually agreed to by the supplier and purchaser of the product. This helps ensure that the flexible barrier materials will comply with the specified requirements.1.1 This guide defines the requirements and considerations for flexible barrier materials.1.2 This guide addresses some critical printing requirements for flexible barrier materials.1.3 Guidance is provided on specification requirements and considerations for flexible barrier materials intended to be purchased as rollstock.1.4 If the flexible barrier material is intended to be purchased in the form of a pre-made sterile barrier system, Guide F2559 should be referenced.1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
