Natural stone standards and testing

For this type of situation, the stone supplier enterprises or construction units should ask the site supervisors to witness the sampling and sent to the stone quality inspection center for inspection or directly commissioned stone quality inspection center for sampling and inspection, stone quality inspection center will send inspectors to the site to extract and seal the sample and bring it back for inspection. Witness sampling of the inspection report will indicate that only the incoming samples are responsible for, the reason is that the stone quality inspection center does not understand the specifics of the stone sampling, because the site supervisors witnessed the taking of samples, so the report is recognized at the site; stone quality inspection center on-site sampling and inspection of the entire batch of stone will be responsible for the inspection report will no longer indicate that only to the incoming samples are responsible for, but it will be indicated in the batch of samples of the number of samples, specifications, sampling Location and so on. Re-inspection of the project is generally set by the project itself, the conventional physical four, granite increased radioactivity report. In China's building code from time to time required to test the freezing performance of stone and other tests, which is not required in the stone product standards, but the stone test method standards have the project, such tests are generally selected according to the project requirements, the inspection report is only data, no judgment, for engineering design reference.

Stone inspection department is also more, the name of the province, city, county have built the corresponding building materials quality inspection station, coupled with the liberalization of the inspection market, cross-industry cross-sectoral inspection agencies compete with each other, there is also a part of the establishment of private inspection agencies, making the inspection market shows the strength of the fight, the fight for the service of the disputes situation. Stone industry in Beijing has an impact on the inspection agency is mainly the National Building Materials Industry Stone Quality Supervision, Inspection and Testing Center, the National Building Materials Testing Center, Beijing Building Materials Quality Inspection Station, which is also recognized by the Beijing Municipal Construction Committee of the three stone inspection agency. Speaking from the instrumentation of building materials testing center is the boss, the most advanced, but with the Beijing Building Materials Quality Inspection Station belongs to a comprehensive inspection agency, stone inspection is not a professional strengths. National Building Materials Industry Stone Quality Inspection Center is the stone industry's authoritative testing organizations, bear all the stone industry standards for the preparation of revisions and standards of interpretation and implementation of the stone industry testing is equipped with adequate equipment, not only quality and quantity to complete the stone inspection tasks, but also in the new situation to convert the concept of improving the sense of service, focusing on the development of the entire stone industry and technological advances, tracking foreign Advanced technology and information, all-round service for the stone industry.

Stone testing commissioned by the program is very simple, first of all, according to their actual needs, with the necessary samples, to the stone quality inspection department to fill out a duplicate commissioned inspection form can be. Stone quality inspection department will be notified to receive the report of the time or as required to send the report, for the test is not clear or samples can be called at any time to the quality inspection department for advice, for the commissioning of door-to-door sampling test or other forms of inspection can be directly commissioned by phone or fax commission. Stone Quality Inspection Center will be happy to serve the user, the following table is a routine inspection of the sample specifications and inspection cycle, the user should be in accordance with the actual requirements of the sample sent in advance, otherwise there will be a delay in the schedule, because strictly according to the stone standard inspection cycle can not be compressed time.
