【英文标准名称】: Standard Test Methods for Internal Pressurization Failure Resistance of Unrestrained Packages 【原文标准名称】: 可伸缩包装的抗内部增压损坏用标准试验方法 【标准号】: ASTM F1140-2007 【标准状态】: 现行 【国别】: 【发布日期】: 2007 【实施或试行日期】: 【发布单位】: 美国材料与试验协会(US-ASTM)【起草单位】: F02.20【标准类型】: (Test Method)【标准水平】: ()【中文主题词】: 损坏频率;软包装件;医学科学;海运包装件;试验方法;运输【英文主题词】: burst; closed package; creep; flexible packaging; inflation; medical packaging; open package【摘要】: These test methods provide a rapid means of evaluating tendencies for package failure when the package is exposed to a pressure differential. Pressure differentials may occur during processes such as sterilization and transportation. These test methods are frequently used to quickly evaluate packages during the manufacturing process and at various stages of the packagersquo;life cycle. If correlations between pieces of test equipment are to be made, it is important that all parameters of the test method be exactly the same. Typical parameters may include, but are not limited to, package size, material, seal configuration, test equipment, rate of air flow into the package, sensitivity (machine response to pressure drop), and position of test article (see Fig. 1). These test methods do not necessarily provide correlation with actual package seal strength as typically measured using Test Method F 88 (or equivalent). FIG. 1 Open Package Test Positions1.1 These test methods explain the procedure for determining the ability of packages to withstand internal pressurization. 1.2 The burst test increasingly pressurizes the package until the package fails.1.3 The creep test maintains a specified pressure for a specified time or until the package fails.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 and health practices and determine the applicability of regulatory limitations prior to use.【中国标准分类号】: A82【国际标准分类号】: 55_180_40【页数】: 5P.;A4【正文语种】: 作者: liuxilin1215 时间: 2014-8-6 19:51:28
