This test method is intended to apply to the testing of all types of plastics, including cast, hot-molded, and cold-molded resinous products, and both homogeneous and laminated plastics in rod and tube form and in sheets asgm.

Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The effect upon these properties of change in moisture content due to d5770 absorption depends largely on the type of exposure by immersion in water or by exposure to high humidityshape of the part, and inherent properties of the plastic.

Formally confirming that your products and services meet all trusted external and internal standards. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. Send us a request Wilton UK: With nonhomogeneous materials, such as laminated forms, the rate of water absorption may be widely different through each edge and surface.

Factors affecting water absorption include: This second function is particularly applicable to sheet, rod, and tube arms when d5700 test is made on the finished product. Assurance Testing Inspection Certification.

For materials of widely varying density, relation between water-absorption values on a volume as well as a weight basis may need to be considered.

Certification Xstm confirming that your products and services meet all trusted external and internal standards. Immediately upon cooling the specimens are weighed. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. For example, Table 1 shows the time to approximate time saturation for various thickness of nylon Specimens are removed, patted dd570 with a lint free cloth, and weighed.

Time to saturation is strongly dependent on specimen thickness. Link to Active This link will always route to the current Active version of the standard. Need help or have a question? Even for otherwise homogeneous materials, it may be slightly greater through cut edges than through molded surfaces.
