What is the difference between ASTM and AATCC?
ASTM International’s Committee D13 develops test methods and specifications for textile materials. In general, AATCC methods tend to focus on colorfastness, wet testing, and chemical analysis. ASTM tests evaluate physical properties of textiles. AATCC and ASTM have published several joint Testing Supplements.
What are AATCC standards?
The American Association of Textile Chemists and Colorists (AATCC) publishes standards for test methods of fiber analysis, colorfastness, color measurement and other textile elements. More than 200 accepted procedures are available.
What is AATCC test method?
The American Association of Textile Chemists and Colorists develops the test methods the textile industry uses to ensure product quality. AATCC textile products allow you to maintain and run a standardized testing environment to assist you in reaching world-class reliability.
What is ISO and AATCC?
Like AATCC, the International Organization for Standardization (ISO) publishes test methods for evaluating textile materials. In fact, many ISO colorfastness and water resistance tests are taken directly from AATCC test methods.
What ASTM means?
American Society for Testing and Materials
Home » Resources » Glossary » American Society for Testing and Materials (ASTM) Currently known as ASTM International, “American Society for Testing and Materials”, ASTM is a developer of international voluntary consensus standards.
What is Aatcc 79?
AATCC 79, 2018 Edition, 2018 – Test Method for Absorbency of Textiles. Purpose and Scope. The test method is for the determination of the water absorbency of yarns, fabrics and garments. It can be used on textiles of any fiber content or construction, including woven, knit and nonwoven.
What is ISO in textile?
ISO is an acronym that stands for the International Organization for Standardization. The term comes from a Greek word ISOS, meaning equal. The International Organization for Standardization is a group of people from many industries who work to create world-wide uniform industrial standards.
What is maximum salt amount for Turquoise?
Considering that the maximum solubility of sodium sulfate is 500g/L (30°C), and the volume of the chemical tank is limited (generally no more than 800L), when using more diverse mineral powder, the method of adding it in batches should be adopted.
What is Colour fastness to sea water?
Colorfastness to sea water test in intended to determine the resistance of the color of dyed, printed, or otherwise colored textiles to immersion in sea water. Artificial sea water is used in this test because natural sea water is variable in composition, and is often difficult to obtain.
What are textile testing standards?
ISO textile testing standards includes tests to ensure the colorfastness of dyed goods. A whole set of standards is in place for evaluating the electrostatic propensity of materials, or the degree to which they give off an electric shock if they’re rubbed or come into contact with other materials.
What are the 5 types of standards recognized by ASTM?
ASTM stands for the American Society for Testing and Materials and has created six types of standards that relate to manufacturing processes such as testing, materials classification and operation. The six types are test method, specification, classification, practice, guide and terminology standards.
Is ASTM a code or standard?
ASTM is an organization that defines and publishes technical standards related to the quality of materials that can be used in the manufacturing of various products and pieces of equipment. ASTM code is made up of the standards that have been developed by committees within ASTM.
What is Oeko Tex 100 certified?
What Is Oeko-Tex Standard 100? Developed in the 1990s by the International Oeko-Tex Association, the Standard 100 is the most well-known and trusted certification for product safety. It is granted to articles tested free of high levels of over 100 toxic substances.
What is GPT and FPT in textile testing?
What are GPT and FPT in textile testing? GPT stands for Garment Performance/ Package Test, and FPT stands for Fabric Performance/ Package Test.
What happens when turquoise gets wet?
Turquoise is a compound that includes metals such as aluminum, copper or iron. Water and oil can cause some of these metals to oxidize, or in other words rust. As a result of oxidation, the stones can actually change color.
Is turquoise rarer than diamonds?
By definition of rarity (not market size) turquoise is rarer than diamonds. Diamonds deserve their place in the world of gemstones as a commerce gemstone. They are an easy gemstone and subject to learn about and grade.
How is color fastness measured?
The colour fastness following exposure to light of a material is defined as the level of change in colour it undergoes when exposed to light (ISO 105 B02:1994). This is measured using a specimen of the fabric to be tested.
How many types of color fastness are there?
Light fastness, wash fastness, and rub fastness are the main forms of colour fastness that are standardized. The light fastness of textile dye is categorized from one to eight and the wash fastness from one to five, with a higher the number indicating better fastness.
What are the 3 types of fabric testing?
Textile Testing.
What is difference between ASME and ASTM?
Basically ASTM creates the material specifications and standard test methods to determine compliance. ASME selects those ASTM materials which will perform adequately in boiler or pressure vessel service and accepts them with stated limitations.
What are the 4 types of standards?
Standards can also be classified according to their degree of formality, depending on who initiates the standardisation process.
- Formal standards.
- Informal standards.
- Proprietary standards.
What is difference between ASTM and ASME?
Is OEKO-TEX trustworthy?
OEKO-TEX® labels are a trusted solution. Our labels help you make safer and more sustainable decisions. Toxins on some textiles can harm your health through breathing, skin contact and saliva. STANDARD 100 by OEKO-TEX® certified products have been tested for harmful substances to protect your health.
Does OEKO-TEX mean no formaldehyde?
Oeko-Tex is a one-size-fits-all certification. By design, the Oeko-Tex 100 protocol must work for all fibers including polyester, nylon, cotton, and rayon. So, Oeko-Tex allows formaldehyde, or it wouldn’t work for the one-size-fits-all approach.
What is FOB in textile?
FOB is the abbreviation of Free On Board. In the context of garment manufacturing industry, FOB means the price for the garment. This price includes the following components: fabrics, trims, accessories, cost of labor and profit from A to Z.
