SIST EN 323:1996 is a Slovenian standard from SIST for measuring the density of test pieces made from wood-based panels. It specifies a test method for density, and the result may be used to estimate the density of wood-based panels according to EN 326-1, clause 6.

What does SIST EN 323:1996 specify?

SIST EN 323:1996 specifies a method for determining the density of test pieces of wood-based panels. In practice, that means the standard is used when a laboratory or manufacturer needs a consistent density value from a sample taken from a panel.

The standard is aimed at panel testing rather than at installed products. Its result can also support density estimation under EN 326-1, clause 6, so the measurement has value beyond the immediate test piece and can feed into broader product assessment.

What are the key requirements of SIST EN 323:1996?

SIST EN 323:1996 is centered on one technical task: determine the density of a test piece in a defined way. For readers, the important point is that the standard is about a measurement method, not about product design or installation.

• Measure density on test pieces - the standard applies to pieces taken from wood-based panels, so users need a sample suitable for laboratory measurement.
• Use the specified method - the document gives the method for determining density, which is what makes results comparable between tests and between organizations.
• Relate the result to panel assessment - the density result may be used to estimate the density of wood-based panels under EN 326-1, clause 6, so the measured value can support higher-level product evaluation.
• Work with wood-based panels in general - the scope covers wood-based panels broadly, so the method is not limited to one narrow panel type in the wording given here.
• Treat the outcome as a test result - the standard’s practical value is in quality control, conformity checking, and comparison of materials, where a consistent density figure is needed.

What terms does SIST EN 323:1996 define?

SIST EN 323:1996 uses a small set of core terms that matter for the test method.

• Wood-based panels - the panel products covered by the standard; density is determined for samples taken from them.
• Test pieces - pieces prepared from the panels for measurement; they are the actual objects tested.
• Density - the property the standard measures; in practice, it is the basis for comparing panel material and quality.
• EN 326-1 - the referenced standard whose clause 6 may use the density result to estimate panel density.
• Clause 6 - the part of EN 326-1 named in the scope as a place where the density result may be used.

Who uses SIST EN 323:1996?

SIST EN 323:1996 is used by testing laboratories, wood-based panel manufacturers, quality managers, and buyers who need a common way to check density. It is relevant in the wood products sector whenever a density value from a test piece must be measured, recorded, or compared with other results.

What changed in SIST EN 323:1996 from the previous edition?

SIST EN 323:1996 is identical to EN 323:1993.

Which standards are used with SIST EN 323:1996?

EN 326-1 is named in the scope as the standard whose clause 6 may use the density result from this method. It provides the context for estimating wood-based panel density from the test piece measurement.

What does the SIST EN 323:1996 document contain?

SIST EN 323:1996 contains the test method for determining density of wood-based panel test pieces. The document’s practical content is the measurement procedure that turns a sample into a density result.

It also connects that result to EN 326-1, clause 6, so the document supports not only laboratory measurement but also downstream panel assessment. For readers, that means the standard is useful wherever density needs to be measured in a repeatable way and then used in product evaluation.
