Zhejiang Longfilament Geotextile What are the testing standards?
Zhejiang Longfilament Geotextile As a highly important product, the country's testing standards for it are critically significant. So then, Zhejiang Longfilament Geotextile What are the testing standards, exactly? Let’s take a look and introduce them to everyone below.
1. Polyester Zhejiang Longfilament Geotextile The criteria for determination
If more than one batch fails or if there are any failing technical performance indicators, an additional sample must be drawn—doubling the original number—from the same batch for retesting of the specific failing items. If the retest still reveals any failures, the entire batch is classified as non-compliant. However, if the retest results are satisfactory, the batch is deemed compliant.
2. Zhejiang Longfilament Geotextile The sampling
Zhejiang Longfilament Geotextile The quality of the product is determined on a batch-by-batch basis: three rolls are randomly selected and tested according to the GBT17639-2008 standard. From the samples that pass inspection, an additional sufficient number of test specimens are randomly chosen.
3, Zhejiang Longfilament Geotextile The testing batch
Zhejiang Longfilament Geotextile Products are inspected on a batch-by-batch basis, using the same formulation, specifications, and production process. For products manufactured continuously under identical conditions, batches consist of up to 50 tons. However, if daily production is low and the total output over a 6-day production period falls short of 50 tons, then the entire 6-day production run will be treated as a single inspection batch.
4. Zhejiang Longfilament Geotextile Type testing
The type-testing items cover all technical performance requirements specified in the national standards. Under normal circumstances, such testing is conducted once every two years; however, it should be carried out immediately if any of the following conditions arise:
1. When production is halted for more than 6 months and then resumes;
2. When there are significant changes to the product's raw materials, formulation, or manufacturing process;
3. Trial qualification assessment for newly developed products or existing products being transferred to a different factory for production.
4. When the factory inspection results differ significantly from the previous type-test results;
5. Factory Inspection of Long-Silk Geotextiles from Shaoxing, Zhejiang
Testing conducted according to the national GBT17639-2008 standard.
