Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 19977-2005 "Textiles anti hydrocarbon oil repellency test" and GB/T 19977-2005 phase
Ratio, the main differences are as follows.
--- The scope of the "handlers washing and dry cleaning is recommended GB/T 8629 or GB/T 19981.2" adjust the injection, and
"GB/T 19981.2" changed to "GB/T 19981 (all parts)."
--- Chapter 6 reagent added "the longest shelf life of 3 years."
--- 9.1.1 and 9.1.2 of the deleted number is incorporated 9.1, the requirements of the device is adjusted to 7.3 and 7.4.
--- Removed in step 9.3 "by 10.2 Assessment of the sample test solution is effective level" of 9.4 and 9.5 modified the formulation, 9.5
The increase in "dropping up to six kinds of test solution on each specimen."
--- Revised 10.2 in "suspicious valid" condition.
--- Increase in Appendix B "oil repellent performance evaluation."
This standard uses redrafted Law Amendment uses ISO 14419.2010 "Textiles anti hydrocarbon oil repellency test" (in English).
This standard and ISO 14419.2010 as compared to the main differences are as follows.
--- Increase the applicable range of products that simplify the instructional content, delete the Note 2.
--- The normative reference document ISO standard to replace the corresponding national standards.
--- Delete Chapter 6 No. 0 in Table 1 and 6.2.
--- The 7.2 "white paper textile aspiration" to "white liquid-absorbent pad."
--- Chapter 10 will be summarized as follows. "10.1 droplets category or description"; "a level of 10.2 samples if the test solution of 'effective' assessment"; "10.3
Single specimens oil repellent grade determination. "Make the content clearer and easy to operate.
--- Increase in Appendix B "oil repellent performance evaluation."
The standard proposed by China Textile Industry Association.
The standard basis by the National Textile Standards Technical Committee of Standardization Technical Committee (SAC/TC209/SC1) centralized.
This standard is mainly drafted by. Textile Standard (Beijing) Inspection and Certification Center Co., Ltd. Jiang Su Xianghong printing.

Textile anti-hydrocarbon oil repellency test
1 Scope
This standard specifies the performance of the oil-repellent fabric method using a series of liquid hydrocarbons having different surface tension measurement.
This standard applies to all types of fabrics and products.
This standard is intended to provide guidance for the buildup of oil resistant properties. Standards can give a rough oil repellency grade, the higher the oil level is generally refused, the sample
Oil resistance material, particularly against liquid oils contaminated with better performance. This standard is particularly suitable for comparison of the same fabric treated with different finishes
Oil repellent effect after finishing. This standard can also be used to determine the washing and dry-cleaning oil repellency treatment on a sample of.
Note. washing and dry-cleaning handlers refer to GB/T 8629 and GB/T 19981 (all parts).
This standard does not apply to assess the anti-penetration properties of the sample of oil chemicals.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein
Member. For undated references, the latest edition (including any amendments) applies to this document.

3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Level grade
Indicative of the quality characteristics of a multi-level reference to any standard level of symbol hierarchy.
Note. The stage represents the standard reference levels are obtained with a level of quality of the sample.
3.2
Oil repellency oilrepelency
Fabrics absorb oil resistance properties of the liquid.
Principle 4
The selected series of hydrocarbons of different surface tension standard test solution was added dropwise to the sample surface, and then observed wetting, wicking and contacts
Case angle. Oil repellent grade to the highest test solution does not wet the sample numerals.
5 Safety Precautions
Safety Warning. These security measures are merely an information measures is to assist the test program but does not contain therein. This standard does not indicate
All possible security issues, when the material of the standard operation, the user has the responsibility to use appropriate and safe methods of material
Safety data records and other manufacturer's recommendations and other specific details should consult the manufacturer.
5.1 should follow good laboratory practice. When processing solution, to wear safety goggles and liquid impervious gloves.
