Precision Testing & Certification


The worldwide trend towards better quality products and the increasing emphasis on product reliability, safety and health standards have made testing and quality control an integral part of any manufacturing processes.

PTC has comprehensive and advanced facilities for testing plastic materials and processing machinery. All tests made are in accordance with national and international standards such as ASTM, BS, DIN, JIS, EUROMAP, IEC, SPC, etc. PTC can provide not just quantitative figures, but also in-depth analysis and interpretation of the measurements and testing results.
