ANSI/AAMI/ISO 11607, "Packaging for Terminally Sterilized Medical Devices," states that "various methods can be used to determine seal strength, e.g., tensile strength testing and burst/creep pressure testing." 1 The standard goes on to state that "there is no general correlation between tensile strength and burst/creep testing. They are .Creep testing on plastics and composites Material Meets Engineering 2019 June 18, 2019 Lukas Unger. The Stepped Isothermal Method (SIM) offers savings of time and costs by temperature steps on 1 specimen. 6. Applications. Pharmaceutical & Medical Packaging News staff . ASTM F1140 suggests beginning the test with a creep pressure that is about 80% of the burst value. Different seal adhesives, such as pressure-sensitive adhesives, may need a lower creep-test pressure to be effective. Inflation rate is not critical as long as the initial fill is not too fast to .
Leak Pointer 3 / 3+ Package Leak Detector provides creep testing of MAP products & accurate non-destructive leak detection in the food industry. . Dansensor Lippke 5000 provides r eliable seal strength and pressure leak testing of many types of packaging. It can be used production, laboratory environments and throughout the supply chain to .The document divides the testing into two separate areas: Performance Characteristics temperature, humidity, pressure, light, cleanliness, and electrostatic conductivity Package Properties microbial, physical and chemical properties, sterilization, and biocompatibilityCreep And Creep Testing To do creep testing, a tensile specimen is subjected to steady tension at a constant temperature, usually by suspending weights from it. . Packaging Material . ASTM F88; ASTM F3039; ASTM F1608; ASTM D7709; ASTM D7734; ASTM D3330; ASTM E1417; ASTM D6834-02; Iron and Steel Products . ASTM E572-13; ASTM E572 .This series of test methods consist of burst test, creep test, and creep to failure which all have determination of intended results. The burst test increasingly pressurizes the package until the package fails, while the creep test keeps a specified pressure for a specified amount of time or until the package fails.

ASTM F1140: Creep test; The creep test is based on internal pressurization, similar to the burst test listed above. This part of package testing maintains a specific pressure in the package for a set amount of time (or until the package fails). Creep testing is used for flexible packaging of differing sizes and seal configurations.A high-resolution tester for flawless seal integrity testing of porous and non-porous packaging. The intelligent Integra -pack is so easy to use, with several automatic modes that help characterize your packaging. It’s ideal for burst (ASTM F1140 and F2054), and pressure decay testing of your flexible packaging. Systech Gaspace 6000
An article on creep and creep testing. Creep is a slow failure mechanism which may occur in a material exposed for a protracted length of time to a load below its elastic limit. . Failure to be able to do this may result in, for example, the premature failure of a pressure vessel or the fouling of gas turbine blades on the turbine casing.
This easy-to-use instrument offers quality creep to fail testing, as well as leak, burst and strength testing. We also have an exciting range of Universal Testing Machines that offer accurate creep to fail testing alongside a whole range of other applications. With both floor models UTMs and table top UTMs, we have the size and solution to suit .

Perform burst, leak, creep, creep to fail and bubble tests from one instrument – or try the combined test option to conduct a simultaneous leak, creep and burst test on a single package. It is ideal for testing rigid, semi rigid and flexible packaging, as well as porous and laminated foils for the food, pharma and medical industries.Figure 1. The creep test experimental set-up. Figure 2. Experimental creep data for (a) Pb5Sn alloy and (b) Sn3Ag0.5Cu alloy. The experimental data points obtained at different testing temperatures are plotted with different symbols. The solid lines are plotted using the constitutive equations, constructed from the entire set of creep data.Multi-station packaging pressure test: Tensile test of packaging materials with ultra-long elongation: Heat-seal strength test for cap films of medical bottles, yogurt cups and jelly cups .

Home Instruments & Meters Test Instrument Test Machine ISO 11607 Packaging Testing Instrument for Burst, Creep, Leak Test US,600.00-5,800.00 / Set1.3 The creep test maintains a specified pressure for a specified time. 1.4 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 .Creep Test: Creep testing evaluates the deformation or stretching of packaging materials over time. It is vital for assessing long-term structural integrity and stability. Particularly relevant in industries where packaging materials are subjected to prolonged stress or pressure, such as in storage or transportation.2: Leak test: The package is pressurized to a predetermined level and is held at that pressure for the required test time. The pressure loss is a quantifi able and repeatable test. (Pressure management and leakage testing per ASTM F2095). 3: Creep Test:The package is pressurized to a preselected pressure, near the
what is a creep test
Limitations: With older Pressure Decay testing devices, the pressurized package will expand in volume. Excessive pressurization may result in seal creep or stretching and skew results. This limits the maximum seal test pressure, especially as package size increases.Some of the most common applications for creep testing include: Pharmaceutical creams . An often mandatory test requested by regulatory bodies creep testing captures a lot of vital rheological information about topical pharmaceutical products. Pressure sensitive adhesives . A creep test is used to check for cold flow behaviour.
This chapter reviews the full range of seal testing techniques used in packaging operations to check for seal faults. The faults that are the subject of the tests can be grouped into three categories: seal strength, leaking seals and seal appearance. . creep testing, creep-to-failure testing and pressure decay leak testing can be used to . Unlike metals, polymers can creep at room temperature under constant loads. The viscoelastic nature of polymers means their creep response is influenced by both elastic and viscous properties. Polyethylene and polypropylene, used in piping and packaging, can deform under sustained stress, necessitating careful design to prevent long-term . Recently, a new indentation creep method was presented, in which the contact pressure is kept constant during the creep test segment, similar to the constant stress applied in a uniaxial creep . Inflation seal-strength testing (ASTM F1140 and ASTM F2054) includes burst, creep, and creep-to-failure testing. Burst testing pressurizes the entire package and captures the peak rupture pressure. This test provides a whole-package minimum seal strength, and is equally applicable to peelable and nonpeelable seals.
ASTM standards provide for several test methods for burst testing, including dynamic, static, creep, and creep to fail tests. . as well as characterize which seal within a package system is the weakest. Request a Quote. Industry Application. Burst testing measures the pressure at which packaging will burst. It is important to note that this .
