This Standard is the revised draft of GB 6545-1986 Corrugated Fiberboard – Determination of Bursting Strength. This Standard was drafted as per the rules specified in GB/T 1.1-1993 Directives for The Work of Standardization - Unit 1.Drafting and Presentation of Standards - Part 1. General Rules for Drafting Standards. This Standard replaced GB 6545-1986 since the date of implementation. This Standard was proposed by China Light Industry Association. This Standard shall be under the jurisdiction of National Technical Committee for Standardization of Paper Industry. Drafting organization of this Standard. China National Pulp and Paper Research Institute. Chief drafting staffs of this Standard. Li Lanfen, and Zhang Shaoling. This Standard was first-time published on June 10, 1986. Corrugated Fiberboard - Determination of Bursting Strength1 ScopeThis Standard specifies using the hydraulic increase method to determine the bursting strength of the corrugated fiberboard. This Standard is applicable to the corrugated fiberboard with bursting strength of 350~5500kPa.2 Normative ReferencesThe following standards contain provisions which, through reference in this Standard, constitute provisions of this Standard. At the time of publication, the editions indicated are valid. All standards are subject to revision. The parties who are using this Standard shall explore the possibility of using the latest version of the following standards. GB 450-1989 Paper and Board - Sampling for Testing GB 10739-1989 Paper Board and Pulps - Conditioning of Samples and Testing Atmospheres3 DefinitionsFor the purpose of this Standard, the following definition apply.4 Test PrinciplePlace the sample on the adhesive film; clamp it with the sample clamp; and then apply pressure evenly to make the sample and the adhesive film freely protrude until the sample ruptures.5 Test Instrument5.1 Sample chuck system The diameter of the upper chuck is (31.5±0.5) mm, and the diameter of the lower chuck hole is (31.5±0.5) mm. The upper and lower clamp rings shall be concentric, and the maximum error shall be no greater than 0.25 mm. The two clamp rings are parallel to each other and flat. The contact surface is evenly stressed during the test. 5.2 Adhesive film The adhesive film is round and composed of elastic material. The adhesive film is firmly clamped, and its upper surface is about 5.5mm lower than the top surface of the lower clamp ring.6 Sample Taking and Handling6.1 The sample shall be taken according to the provisions of GB 450.7 Preparation of SampleThe sample area must be larger than the chuck of the burst tester; and the sample must not have watermarks, creases or obvious damage.8 Test ProceduresCut samples and test under the atmospheric conditions specified in 6.2. Open the sample chuck; clamp the sample in the middle of the two sample chucks; then start the analyzer; and gradually increase the pressure at a rate of (170±15) mL/min.9 Result ExpressionThe test is carried out on 10 samples each attached to the film on the front and back sides, and is expressed by the arithmetic mean value (kPa) of all tested values.10 Test ReportThe test report includes the following contents. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al. |
