SIST EN 1164:2000 is a Slovenian standard from SIST that adopts EN 1164:1998. It gives a laboratory test method for feather and down, used to judge cleanliness by measuring turbidity in an aqueous extract. In practice, it helps laboratories, suppliers and buyers assess whether feather and down ready to be used contains unwanted soluble or undissolved matter.
What does SIST EN 1164:2000 specify?
SIST EN 1164:2000 specifies a method for checking one aspect of the cleanliness of feather and down ready to be used. The check is based on determining the amount of dissolved and undissolved matter present in an aqueous extract.
For users, that means the standard is about a test result you can measure in a lab, not a visual inspection or a general quality statement. It gives a common way to compare materials and document cleanliness in a repeatable way.
What are the key requirements of SIST EN 1164:2000?
SIST EN 1164:2000 focuses on preparing an aqueous extract and using its turbidity as the basis for the cleanliness check. The practical point is that the material is not judged directly; it is first transferred into water so the extract can be examined.
The most important points are:
- Aqueous extract - The feather and down are examined through the liquid obtained from them. In practice, this means the sample must be handled in a way that makes its soluble and suspended matter measurable.
- Turbidity - The standard uses turbidity as the indicator of cleanliness. For the reader, this means the test outcome depends on how cloudy the extract is.
- Undissolved matter - The method considers material that remains suspended rather than dissolving. This matters because suspended particles can show contamination or insufficient cleaning.
- Dissolved matter - The method also considers material that goes into solution. This matters because water-soluble residues can affect the cleanliness assessment even when the liquid looks clear.
- Feather and down ready to be used - The standard applies to material prepared for use, not to raw or unrelated products. In practice, this is the stage where a buyer or processor needs a quality check.
- Cleanliness aspect - The method covers one specific quality aspect, not the full performance of the filling material. That means the test supports a focused acceptance or control decision, rather than replacing broader product specification checks.
- Test method format - The document is a test-method standard. For users, this means it is meant for laboratory work, results comparison and reporting under a common procedure.
What terms does SIST EN 1164:2000 define?
Feather and down are the filling materials covered by the standard, used here as the product under test.
Aqueous extract means the liquid obtained by treating the sample with water so that substances from the material can be examined.
Turbidity is the cloudiness of the extract, used as the observable sign linked to cleanliness.
Undissolved matter is material present in the extract as particles or residue rather than as dissolved substance.
Dissolved matter is material that passes into the water and contributes to the extract even if it cannot be seen as particles.
Cleanliness in this standard means the condition being checked by the turbidity test, specifically the presence of unwanted matter in the extract.
Who uses SIST EN 1164:2000?
SIST EN 1164:2000 is used by laboratories that test feather and down, by manufacturers and processors of filling materials, and by buyers or quality managers who need a common cleanliness check. It is relevant wherever feather and down are assessed before use, especially in supply and quality-control work.
The standard is also useful for anyone who needs comparable test results between suppliers or batches. Using the same method helps reduce disputes about whether the material has been cleaned to an agreed level.
What changed in SIST EN 1164:2000 from the previous edition?
SIST EN 1164:2000 is identical to EN 1164:1998.
What does the SIST EN 1164:2000 document contain?
SIST EN 1164:2000 contains the standard’s bibliographic pages and the test method for determining turbidity in an aqueous extract of feather and down. The document is presented as a European standard adopted in Slovenia and identified for textile auxiliary materials.
Its technical content is a laboratory method rather than a product specification. The reader should expect instructions for carrying out the extract-based cleanliness check and using the result to assess feather and down ready to be used.
