Foreword
This revised standard adopts ISO 1420.2001 "Rubber or plastic coated fabrics - Determination of resistance to water."
This standard is based on ISO 1420.2001 re-drafting, and ISO 1420.2001 The main differences are as follows.
1. Normative documents of international standards to replace national standards;
2. Deleted range described specimen shape, increasing the terms "may refer to other waterproof fabric execution ';
3. Increasing the test results or not explain;
4. Increasing the final determination of hydrostatic values (6.4) and the representation of the results.
Instead of the standard FZ/T 01004-1991 "Standard Test Method for Coated Fabrics resistance to water (hydrostatic pressure test)."
This standard FZ/T 01004-1991 made the following modifications.
1. Increase the normative references;
2. Test Method consists of four into a unified;
3. The elimination of the low and high pressure test equipment instrument, to a general-purpose test equipment;
4. Increasing the specimen shape and size requirements;
5. Abolition of the "standard atmosphere" and "water" chapters, the humidity and atmospheric testing standards do not make specific provisions, the humidity will be time to at least
16h;
6. Revised test procedure;
7. Added "Test results" chapter.
The standard proposed by China Textile Industry Association.
This standard by the National Standardization Technical Committee based textile branch (SAC/TC209/SC1) centralized.
This standard is drafted by. National Textile Products Quality Supervision and Inspection Center.
The main drafters of this standard. Li Chun, Lizhi En, Lister, Yan Chunhong.
This standard was first published in 1991, this revision is the first time.
Determination of resistance to water penetration of the coated fabric
1 Scope
This standard specifies the method within a fixed period of time applying hydrostatic pressure on coated fabrics, coated fabrics Determination of resistance to water.
This standard applies to coated fabrics, other waterproof fabric can be implemented by reference.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
GB 6529 textiles conditioning and testing - Standard atmospheres
Principle 3
Under specified conditions, the test sample coated fabric side by the rising water pressure, until the pressure reaches a predetermined value. In Regulation
Given time to see if there is penetration occurred or continue pressing until penetration occurs.
4 Instrument
4.1 Summary
Instrument consists of an open container with a specimen holder device components. Bottom of the container has an inlet, and filled with room temperature water inlet pipe
Connected. Above there is a specimen sample to prevent deformation, cracking metal mesh, metal mesh aperture periphery grow up to 30mm, the straight
Made of 1.0mm ~ 1.2mm diameter wire.
4.2 Range and Accuracy
You can use a pressure gauge or manometer measuring hydrostatic pressure.
Pressure gauge. connected to the test head, the water pressure up to 19.6kPa (200cm water column) with an accuracy of ± 1%.
Pressure gauge. maximum range of at least 100kPa (1020cm water column).
4.3 Test Area
Caught in the open container of sample test area of 100cm2, that is, as the sample is a square side length
