Name:instrument for Impact resistant tests
Description:Topics: Impact resistant strength of road stud Objectives: Impact resistant Strength of RPM and solar RPM. Conditions and Procedures: according to ASTM 4280. Materials and Instrument: instrument for Impact resistant tests Lens Impact Strength: condition the markers in a convection oven at 55 degrees(130F)For 1h. While at the elevated temperature,impact the reflective face of the marker by allowing a 0.19kg(0.42lb)dart fitted with a 6.4mm(0.25in)radius semi-spherical head to drop 457 mm(18 in.)perpendicularly onto the approximate center of the reflective surface. For impact testing, set the marker on a steel fixture designed to hold the reflecting face horzizontal, and place the fixture on a solid surface, such as a concrete floor. Inspect for cracking and delamination. No damage or crack beyond diameter 12mm with the impact point as center.

Name:compressive stress machine
Description:Topics: compression resistance of road stud Objectives: compression resistance of raised pavement marker (hereafter "RPM) and solar powered raised pavement marker (hereafter "solar RPM). Standard: 160KN (RPM), 100KN (solar RPM) Materials and Instrument: compressive stress machine Conditions and Procedures: according to ASTM 4280 Mechanical performance of RPM & solar RPM: Put the RPM on the platform of compressive stress machine (compressive stress head/end surface bigger than the stressed surface of the RPM). Place a soft rubber sheet on the RPM, loading step by step at a speed of 20KN/min-30Kn/min. Stop loading till it is up to 160KN. Inspect the RPM, and it should not break or crack with a load of over 160KN; while the solar RPM should charge and discharge in good condition with a load of over 100KN.

Name:testing machine for flexibility of delineator post
Description:Topics: flexibility Objectives: flexible delineator etc, made of flexible plastic Conditions and procedures: conditions of flexibility tests according to international standard of traffic safety products Materials and instrument: new criteria Standard: tests for flexibility-resistance performance Ambient temperature: 15Celcius - 25Celcius. Install the traffic post in the testing machine according to manufacturers' instructions. There is a tyre with diameter 54cm and switch A and B on the machine as illustrated below. Operate the machine. The tyre runs from left to right at a speed of 20m/min and roll on the post; when the tyre comes to switch B, run it from right to left at the same speed and roll on the post. After 200 cycles test with this method, no crack, breakage or separation should be found on the post, its base or the reflective tape while the post should restore itself to what it was. Remaining declination of the post top toward any level directions should not go beyond 7% of the post height.
