What is moisture content test?
The basic method is to carefully weigh the specimen in its original state, drying the water contained in the specimen, then re-weighing. Precisely HOW this is done depends upon the material.
What is ASTM D2216?
ASTM D2216 : Standard Test Methods for Laboratory Determination of Water (Moisture) Content of Soil and Rock by Mass. Item.
What is ASTM d4643 all about?
Standard Test Method for Determination of Water (Moisture) Content of Soil by the Microwave Oven Method. 1.1 This test method outlines procedures for determining the water (moisture) content of soils by incrementally drying soil in a microwave oven.
What is ASTM test method?
ASTM test methods are petroleum industry standards, accepted worldwide for quality and reliability. ASTM test methods for petroleum and refined products include: Petroleum and Petrochemical Test Directory. ASTM Tests for Petroleum, Fuels and Petrochemicals.
What is the purpose of moisture content?
Moisture content of the food material is important to consider the food is suitable before the consumption, because moisture content affects the physical, chemical aspects of food which relates with the freshness and stability for the storage of the food for a long period of time and the moisture content determine the …
Why is moisture content test done?
Determine the natural content of the given soil sample. In almost all soil tests natural moisture content of the soil is to be determined. The knowledge of the natural moisture content is essential in all studies of soil mechanics.
What is moisture content of soil?
The moisture content of soil is described as the ratio of the mass of water held in the soil to the dry soil. The mass of water is determined by the difference before and after drying the soil.
What is oven drying method?
The drying oven method is a thermogravimetric method (loss on drying) in which the sample is dried for a defined period of time at constant temperature. The moisture content is determined by weighing the sample before and after drying and determining the difference.
Why is ASTM important?
ASTM helps to ensure that only quality, raw materials are used to produce bearings and other industrial goods. What is ASTM? – ASTM (formerly American Society for Testing and Materials) is the governing body of the plastics industry and the group responsible for classifying the quality of raw materials.
What is the principle of moisture content?
The principle of the thermogravimetric method of moisture content determination is defined as the weight loss of mass that occurs as the material is heated. The sample weight is taken prior to heating and again after reaching a steady-state mass subsequent to drying.
What is the difference between moisture content and water content?
The key difference between moisture content and water content is that moisture content determines the amount of water vapour and other volatile components present in a sample, whereas water content determines the amount of water in a sample.
What is the purpose of ASTM?
ASTM is one of the world’s largest standards developing organizations. An independent, not-for-profit organization, ASTM serves as a forum for producers, users, consumers, and those having a general interest (representatives of government and academia) to meet on common ground and develop voluntary, consensus standards.
What is the meaning of ASTM?
ASTM stands for the American Society for Testing and Materials. The ASTM sets safety standards for many different materials, including those that go into sports equipment – including protective helmets designed for equestrians. The ASTM consults with experts in various fields (including medical)…
What is the equation for moisture content?
Calculate the moisture content on a wet-weight basis using the following formula: Moisture content (%) = W2 – W3 x 100 W2-W1. where, W1 = weight of container with lid; W2 = weight of container with lid and sample before drying; and W3 = weight of container with lid and sample after drying.
What is in the ASTM standard?
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 .
