Remarks You may have a look at our Certificate of Accreditation and Scope of accreditation on our official website https://ptsbg.eu/en/services/pt-provider/. Important about the test samples from “Asphalt mixture”: Preparation of test samples for determination of “maximum density” shall be performed according to EN 12697-28:2020 “Bituminous mixtures - Test methods - Part 28: Preparation of samples for determining binder content, water content and grading”, as it is stated in EN 12697-5:2019. Preparation of test samples for determination of “bulk density”, “stability” and “flow” shall be performed according to the procedure of EN 12697-30:2018 “Bituminous mixtures - Test methods - Part 30: Specimen preparation by impact compactor” at 140 ⁰C and 75 blows on each side. Important about the test samples from “Bitumen”: Preparation of test samples shall be performed according to EN 12594:2014 “Bitumen and bituminous binders - Preparation of test samples”. Important about sampling from “Aggregates (fine or all-in material)” for subsequent testing: Preparation of test samples shall be performed according to EN 932-2:1999 Tests for general properties of aggregates - Part 2: Methods for reducing laboratory samples”. The participation fee includes: taking and reducing of the samples, preparing of the test subjects, homogeneity and stability tests, packing, distribution/shipping, statistical analysis, preparing and receiving of a report in Bulgarian and English languages (PTS-F 4.8-1) and a certification of participation (PTS-F 4.9-1) in interlaboratory comparison and proficiency testing. The report will be sent via mail. The certificate of participation will be sent via mail (scanned copy) and via post office (original)!
