Can gypsum board inspection** be done? What are the gypsum board testing items and standards? How much does gypustboard fracture load testing cost? How long does it take for a drywall inspection report to be issued? Foshan Huajin's third-party material testing laboratory can provide all kinds of gypsum board testing services, including quality testing, composition testing, breaking load, combustion performance, water absorption, impact resistance, RoHS testing, etc. As a third-party testing center, the institution has CMA, CNAS certification and testing qualifications, complete testing equipment, scientific and reliable data, and can issue a nationally recognized gypsum board test report within 5-10 working days.
Gypsum board is a material made of building gypsum as the main raw material. Gypsum board is a kind of light weight, high strength, thin thickness, easy processing, sound insulation, heat insulation and fire protection and other good performance of building materials, is one of the current focus on the development of new lightweight board. Common gypsum boards are generally divided into three types: ordinary paper gypsum board, waterproof (water-resistant) gypsum board, and fireproof gypsum board.
With the rapid development of the construction industry, the use of gypsum board is becoming more and more extensive. The inspection of gypsum board has also become one of the important measures to ensure the quality of construction. So should the gypsum board inspection report go to **? How much does the inspection cost? Below, this article will answer these questions.
First, the inspection principle of gypsum board:
The inspection of gypsum board is an important part of ensuring that gypsum board meets national standards and related quality requirements. The inspection principles of gypsum board usually have the following aspects:
1.The inspection should be carried out in accordance with the national standard for gypsum board, and only gypsum board that meets the standard can be recognized and finally used in construction projects.
2.The inspection should cover key performance indicators such as the quality, size, tensile strength, density and moisture content of the gypsum board to ensure the quality of the gypsum board.
3.The inspection should be carried out by a professional testing agency to ensure the accuracy and reliability of the test results.
Second, what items are tested by gypsum board:
There are many gypsum board testing items, and the testing items are different according to the different conditions of use and the environment. Common test items are: flame retardant grade, fire resistance limit, surface water absorption, dimensional deviation, breaking load, diagonal length difference, adhesion between the face protection paper and the core material, impact resistance, areal density, appearance quality, water absorption, wedge-shaped edge section size, hardness, fire stability, etc.
Third, the cost of gypsum board inspection report:
The cost of the gypsum board inspection report needs to be determined on a case-by-case basis. Factors such as different testing institutions, different regions, and different amounts of gypsum board will have an impact on **. Generally speaking, the cost of a gypsum board inspection report is calculated on a per square meter or per sample. There may also be additional costs involved, such as sampling costs and shipping costs. Taking these factors into account, the cost of the entire inspection process is generally between 1,000 yuan and 3,000 yuan.
Fourth, gypsum board testing standards:
1. JC T 799-2016 Decorative gypsum board: It stipulates the terms and definitions, classification and marking, general requirements, technical requirements, test methods, inspection rules, packaging, marking, transportation and storage of decorative gypsum board.
2. GB T 9775-2008 gypsum board: This standard specifies the terms and definitions, classification and marking, requirements, test methods, inspection rules, marking, packaging, storage and transportation of gypsum board.
3. JC T 997-2006 Decorative gypsum board: This standard specifies the classification and marking, requirements, test methods, inspection rules, marking, packaging, transportation and storage of decorative gypsum board.
5. Conclusion: Gypsum board is an indispensable part of the construction industry, and the inspection of gypsum board can ensure the quality and safety of construction. In order to ensure the accuracy and reliability of the gypsum board inspection results, it is recommended to choose a qualified testing agency to handle the gypsum board inspection report, and at the same time carefully understand the charging standards of various services before the test, so as to avoid unnecessary troubles in the later stage.
