Assurance Testing Inspection Certification. Auditing Consulting Sourcing Training. Standards can be obtained from appropriate standard authorities. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. This curve is called the seal curve. A series of seals at different sealing temperatures are made, using a machine employing hot-bar jaws.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Each tail of the sealed specimen is secured in the opposing grips of a universal test bench. Send us a request Wilton UK: Combining values from the two systems may result in asrm with the standard.

The maximum tensile force required to separate the two ends of the seal is recorded. Formally confirming that your products and services meet all trusted external and internal standards. Need help or have a question?
Seal strength is the tensile strength of the seal at ambient temperature. Work Item s – proposed revisions of this standard. A number of fixtures and techniques have been devised to hold samples at various angles to the pull direction to atsm this bending force.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Examples of fixtures and techniques are illustrated in Fig. A rectangular specimen is used; the specimen width may be either 25 mm, 15 mm or 1.
Seal strength is not only relevant to opening force and package integrity, but to measuring the packaging processes’ ability to produce consistent seals. Certification Formally confirming that your products and services meet all trusted external and internal standards.

Testing Evaluating how your products and services meet and exceed quality, safety, sustainability ast, performance standards. Unsupported— Each tail of the specimen is secured in opposing grips and the seal remains unsupported while the test is being conducted. Seal strength at some minimum level is a necessary package requirement, and at times it is desirable to limit the strength of the seal to facilitate opening. Evaluating how your products f888 services meet and exceed quality, safety, sustainability and performance standards.
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. A curve can be plotted showing the effect of the sealing c88 mainly temperature on the seal force. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.

It is the maximum force required to separate the two layers of a ashm under particular conditions.
At a certain temperatures a seal force level is reached atsm is related to the maximum tensile force of the film. Historical Version s – view previous versions of standard. Because the effect of each of these on test results is varied, consistent use of one technique Technique A, Technique B, or Technique C throughout a test series is recommended.
