In America, the ASTm (American Society for Testing and materials) regulates gypsum and related building materials and systems through Technical Committee C11. iv. All Rights Reserved. precipitate gypsum from the soil extract by adding acetone. 4.3.1 Gypsum Ready-Mixed Plaster or Gypsum WoodFi-bered Plaster—Screen the dried sample through a 150-µm (No. Mix vigorously (about 150 complete circular strokes per determine the compressive strength of gypsum plaster and minute) for 1 min with a metal spoon, stiff-bladed spatula or gypsum concrete and is used … The requirements specified will also focus on dimensional requirements such as width, length, end squareness, thickness, and edges. 1.1 These test methods cover the physical testing of gypsum, gypsum plasters, and gypsum concrete. The test is an empirical test that measures the workability of fresh concrete. The following types of False Ceilings will be covered. For example, for wood materials, screws should be ⅝” long and 3⁄4” for nails. View Only: Prior Editions of Code-Referenced Documents, 2015 Study on Respirable Crystalline Silica.

If the solution is to be analyzed for its chemical constituents, the saturated paste should stand for 12 hours or more (over night). For more information about our gypsum board testing and certification services, contact us. This specification covers gypsum boards which include the following: gypsum wallboard for use on walls, ceilings, or partitions and that affords a surface suitable to receive decoration; pre decorated gypsum board for use as the finished surfacing for walls, ceilings, or partitions; gypsum backing board, coreboard, and shaftliner board for use as a base in multilayer systems or as a gypsum stud or core in semisolid or solid gypsum board partitions, or in shaft wall assemblies; water-resistant gypsum backing board to be used as a base for the application of ceramic or plastic tile on walls or ceilings; exterior gypsum soffit board for exterior soffits and carport ceilings that are completely protected from contact with liquid water; gypsum sheathing board for use as sheathing on buildings; gypsum base for veneer plaster; gypsum lath for use as a base for gypsum plaster application; and gypsum ceiling board for interior ceilings and walls. C474-15 Standard Test Methods for Joint Treatment Materials for Gypsum Board Construction Repeat the test using this solution. A non-load bearing wall consisting of gypsum panels attached to steel studs was constructed for fire testing. NTA offers a single-source solution for all of your needs related to gypsum wallboard testing, inspection, certification, evaluation, and follow-up services. The concrete slump test is used for the measurement of a property of fresh concrete. Having all the required services performed by a single vendor saves you a significant amount of time and money. If the soil contains gypsum the conductivity can increase by 1 or 2 mS/cm upon standing. The most recommended procedure is a bilateral comparison in which expert judgements or criteria based on fitness for the desired purpose are applied.
