Our team consists of supervisors specialized in various types of products. This axtm varies the drop height for each drop or cycle but with a new test specimen for each. It is also up to the importer to define whether unit packaging may be damaged or must stay visually intact. Your email address will not be published.

Research Report D10— describes an interlaboratory test program of three packaged items, establishing drop heights to failure. Replicate samples should be subjected to identical procedures for comparison and for statistical analysis. While the outer carton almost always deforms, the products may still be protected from breakage. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. It may be a formal study of the relationship between drop orientation and damage, other engineering analyses of that product and package, or laboratory and?

This must be based on n, the number of passes or failures, and not n? Currently you have JavaScript disabled. Precision and Bias A number in parentheses indicates the year of last reapproval. ISTA 1A is a procedure designed to challenge the strength and robustness of the product and package combination. Replicate samples should be subjected to identical procedues to determine the consistency of the failure point.


Get to know us! If the package has one or more side seam joints, one of the joints should occupy the position of It is recommended that special atmospheres for conditioning be selected from those given in Practice D Title 49 —Transportation 49 CFR 4 3. Last previous edition D — Pros and Cons of India or China Manufacturing. Continue dropping on similar cycles until a speci?

If there are more passes than failures, compute the arithmetic mean of the height of the failures and subtract 1? The ASTM-D standard test method for drop test of loaded containers evaluates the capability of a container to withstand the sudden shock resulting from a free fall, or the capability of a container and its inner packing to protect its contents during the sudden shock resulting from a free fall.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, satm entirely their own d2576. Where it is desirable to drop on a midpoint between two locations on the chime, such a point can be designated using two numbers, that is, drop on Several texts6,7,8 on experimental statistics and standards, describe this test procedure in more detail, provide additional calculations, and discuss methods to compensate for nonnormal distributions see Test Methods D and E Quality Management Product Testing: The drum shall be dropped at right angles to the timber.

The use of a log-normal distribution is often suggested but this requires the drop height increment to be a constant based on the d52766 of the drop height, thus the actual drop height increment would change with the drop height.


If this specimen passes at this drop height, the next test will satm at a higher drop height with a new package. We can help you avoid product recalls and production delays.

ASTM D Standard Test Method for Drop Test of Loaded Containers by Free Fall_百度文库

The values given in parentheses are for information only. Get to know the main factors that affect the quality of imported goods. The pooled reproducibility between laboratory standard deviation was 2. These ISO standards may describe procedures d526 do not meet the requirements for this test method. It is common to estimate the critical drop height as the midpoint between the last successful test and the test which caused damage; use of the successful test point before failure may be considered a more conservative estimate.

See Practice D for additional guidance. The drop height shall asmt measured from the top of the timber.

Quality Alerts View All. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

During transport, cartons are subject to shock, vibration, humidity and pressure. 5d276 drop height increment is a constant and should be between 1? This will be in a prescibed orientation or a prescribed cycle of drops. This test method may also be used to compare the performance of different package designs.

It may also permit observation of the progressive failure of a container and the damage to its contents. ASTM-D is particularly suitable for containers that are normally handled manually during some part of their distribution cycle.
