Southern power grid PC material with important test meter box the tender documents, PC material manufacturers will see
1, non-metallic materials list box (PC material panel)
2, the tensile strength: 60 Mpa or greater
3, the bending strength: 95 mpa or higher
4, thermal deformation temperature: 130 ℃ or higher testing instruments: model KP8006 thermal deformation, vicat softening point temperature tester;
5, flame retardant grade: V - 0 testing instruments: model KP8010 plastic and plastic parts \ vertical burning test machine;
6, dielectric strength: p 16 kV/mm testing instruments: model KP8009 solid insulation electrical dielectric strength testing machine;
Simply supported beam with 7, impact strength, impact strength should be 50 kj/m2 or. Testing instrument: model KP8137A support beam impact testing machine;
8, dielectric strength: the support for 50 + / - 5 hz, 2000 v power frequency voltage arcing, breakdown occur 1 minutes don't. Testing instrument: model KP8028A arc resistance tester;
9, climate impact: from the high temperature of 100 ℃ for 4 hours and to 40 ℃ for 4 hours at low temperature environment, restore to 20 ℃ environment, list box is not deformation, not cracking.
Compressive performance: 10, 100 kg weight placed on a table box window or any position for three minutes, table boxes don't crack damage.
11, impact resistant: table box under the condition of fixed screw tightening, from 2 m high free fall test, body intact. Resistance to impact hammer.
12, corrosion resistant, resistant to corrosion, bubble is 4 hours in 0.5% hydrochloric acid solution or 3% of the concentration of acid and alkali solution 1 ml in the face for 1 hour, no obvious corrosion phenomenon.
Above project as a supplement to conventional test
