This section GB/T Part of 413,835.
GB/T 13835.4-1992 "rabbit regain test methods" in this section instead.
This section compared with the GB/T 13835.4-1992 The main changes are as follows.
--- Increasing the GB/T 6529 (Chapter 2 of this edition) normative reference documents;
--- Delete method summary (Chapter 3 edition 1992);
--- Modified apparatus and appliances (Version 1992 Chapter 4; Chapter 3 of this edition);
--- Increased testing standard atmosphere (Chapter 4 of this edition);
--- Improved sampling methods and increased moisture regain test sample preparation method (Version 1992 Chapter 5; Chapter 5 of this edition);
--- Improved test procedure (Edition 1992 Chapter 6; Chapter 6 of this edition);
--- Increasing the normative Annex A (Excerpts Appendix A).
This section of Appendix A normative appendix.

Test method for rabbit hair fiber
Part 4. Regain oven method
1 Scope
GB/T 13835 in this section specifies the method for determining the fiber moisture regain rabbit oven method.
This section applies to the hot tank, said determination rabbit fiber moisture regain.
2 Normative references
The following documents contain provisions which, through reference GB/T 13835 in this section constitute provisions of this section. For dated reference documents
Member, all subsequent amendments (not including errata content) or revisions do not apply to this section, however, encouraged to reach under this section
Parties to research agreement to use the latest versions of these documents. For undated reference documents, the latest versions apply to this
section.
GB/T 6529 Textiles Standard conditioning and testing atmosphere
GB/T 8170 repair value expressed about the rules and limit values \u200b\u200band judgment
GB/T 13835.1 rabbit hair fiber test methods - Part 1. Sampling
3 apparatus and appliances
3.1 eight baskets oven temperature.
3.2 Balance, dividing the value of 0.01g.
3.3 Sheng-like container.
4 standard atmospheric testing
4.1 standard atmospheric test in GB/T 6529 provisions (a temperature of 20 ℃ ± 2 ℃, relative humidity of 65% ± 4%) is carried out.
4.2 in non-standard tests, such as the atmosphere, drying quality should be measured in the test sample value corrected to standard atmospheric conditions. root
According to the test when baking temperature and humidity of the atmosphere surrounding the oven, check the correction coefficient table is corrected coefficient, drying mass multiplied by the correction coefficient is corrected to standard
Drying mass values \u200b\u200bunder atmospheric conditions. Correction coefficient table in Appendix A.
5 Sampling and test sample preparation
5.1 In accordance with GB/T 13835.1 requirements, test samples extracted regain inspection.
5.2 said before taking baking test sample mass. from sample containers containing test samples quickly removed, with the balance weighing accuracy 50g test specimen, to the nearest
0.01g, each weighing accuracy of a test sample should not exceed 1min. A total of eight test specimens.
5.3 before baking test specimens shall be known as a good tear loose, place the piece of glossy paper torn loose, torn off all the debris should be put back to the test sample.
6 Test procedure
6.1 off the oven bake basket, open the oven power supply switch points, will say good test specimen to tear loose fluffy baked into the basket, the basket will bake only by
Checkmark into the oven bake basket hanging on a hook, shut the door.
6.2 until the inside temperature to rise to a predetermined temperature of 105 ℃ ± 2 ℃, the recording time.
6.3 Pre-drying time. pre-bake oven of different models at different times, ordinary eight baskets oven pre-heated drying time of 90min, to reach pre-drying time
After close basket and fan power, recording time, for the first time inside the weighing, make a record.
