1、FAQ – Testing Reports

As a general principle, testing reports based on tests undertaken in a third part testing lab only will be recognized under the CCC scheme. Reports based on TMP/WMP need special approval to be recognized (not recommendable).

2、Resins Testing

As a professional reliability third-party testing organization, T,C&A Lab can provide Resins Testing service according to ISO, ASTM standards and industry requirements.

3、Testing

By providing independent third-party evaluation services, we ensure that your projects, products, processes, and operations not only meet but exceed stringent market regulations and standards. This external verification process is key to maintaining trust and integrity in your business practices.

The Effect of the Addition of Polypropylene Fibers to Primer on the

The primer was made of epoxy resin modified with the addition of 0.5%, 1%, 1.5% and 2% of polypropylene fibers. One reference sample was made without the addition of fibers.

SILVA: TestPrime

From the results of the PCR, TestPrime computes coverages for each taxonomic group in all of the taxonomies offered by SILVA. These coverages can then be inspected in our taxonomy browser, making it easy to quickly identify strengths and weaknesses of a particular pair of primers.

Phase morphology modulation of silicone

In this study, phase control of silicones in modified epoxy resins was achieved by modulating the curing process, and a series of silicone-modified epoxy resins with different phase sizes were prepared.

第三方测试（Third party testing）

acceptable, and generate test results report. Third party regression test: When the old code is modified, the test is repeated to confirm that the modification does not introduce new errors or causes other code errors. Automatic regression testing will greatly reduce the cost of system testing, maintenance, upgrading and other stages.
