Description:Gb/t 1043 "determination of the impact properties of plastic beam is divided into two parts, the right part 1 gb/t 1043, equivalent to the iso 179-1: the plastics - determination of the impact properties of simply supported beam - part 1: the instrumented impact test" (English version), and iso/tc 61 / sc2 released in 2005, no. 1 modify the contents of a single merged into the text.
this part Iso 179-1:2000, exactly on the technical content.
this part instead of gb/t 1043-1993 "the hard plastic beam impact test method".
the gb/t 1043 the provisions of this part of the plastic beam under prescribed conditions to determine the impact strength of the method. Rules for several different types of samples and test. According to the material type, type of test specimen and notch type defines different test The number.
the provisions of this part used to study the types of test specimen under the condition of the specified impact behavior and assess the brittleness and ductility of the specimen under test conditions. Can also be used for the determination of the same material comparable data.
this section applies to the following range of materials: - hard thermoplastic moulding and extrusion materials, including the filling and enhanced materials, hard thermoplastic sheets; - hard thermosetting molding materials, including the filling and enhanced materials, rigid thermosetting plate, Include laminated material; - fiber unidirectional and multidirectional reinforced thermoset and thermoplastic composite materials, such as carpets, fabrics, textiles roving, chopped strand, composite and grated fiber reinforced material, roving, prepreg materials made of a sheet (presoak billet material), including the filling and enhanced materials; - thermotropic liquid crystal polymer.
this section does not apply to rigid foam material and foam sandwich structure. Usually long fiber reinforced composite material and thermal fluid Crystal polymer does not use notch specimen.
this part compared with gb/t 1043-1993 main change is:
- change the standard name, added to discuss, preface;
- to expand the scope of application, increasing the thermotropic liquid crystal polymer;
- terms and definitions content expansion and modification, the reference "lateral shock", "penetration layer shock", "vertical", "parallel to the direction," deleted "phase Several damage type of impact strength ", will return in steps;
- change the position gap degrees of gap, the gap opening in sample narrow longitudinal plane;
- sample size change;
- increases the precision of a chapter,
- expanded the content of the test report;
- increases the appendix a, "additional approach to study the surface effect",
- increases the appendix b" Precision data ".
