What is ISO 16014-2 – SEC calibration for polymers about? ISO 16014-2 is the second part of the ISO 16014 multi-series about polymer characterization using size-exclusion chromatography (SEC). ISO 16014-2 specifies the universal calibration method for determining the average molecular weight and the molecular weight distribution of polymers using SEC. The average molecular weight and the molecular weight distribution are calculated using a universal calibration curve instead of the conventional calibration curve.   Note: This test method is classified as a relative method as described in ISO 16014‑1, but the average molecular weights and molecular weight distributions calculated by the method are equal to, or nearly equal to, the absolute values. Who is ISO 16014-2 - SEC calibration for polymers for ? ISO 16014-2 on SEC calibration for polymers is useful for: Manufacturers of polymers products Testing laboratories / researchers Design engineers / product development personnel Quality control personnel Why should you use ISO 16014-2 - var dom = document.getElementById("std_map_cont"); var myChart = echarts.init(dom); option = { title: { text: 'BS ISO 16014-2:2019 引用关系图' }, tooltip: {}, animation: false, animationDurationUpdate: 1500, animationEasingUpdate: 'quinticInOut', series : [ { type: 'graph', layout: 'force', /*force: {initLayout: 'circular',repulsion:50,gravity: 0.01,edgeLength:[50,500]},*/ force: {repulsion:20,edgeLength:5}, circular: {rotateLabel: true}, /*symbol: 'rect',*/ /*symbolSize: [150,30],*/ roam: true, draggable: true, /* focusNodeAdjacency: true,*/ roam: true, /* label: { normal: { show: true, position: 'right', formatter: '{b}', } }, */ edgeSymbol: ['circle', 'arrow'], edgeSymbolSize: [2, 6], edgeLabel: { normal: { textStyle: { fontSize: 10 } } }, data: [ {name: "BS ISO 16014-2:2019",symbol: 'circle',symbolSize:20, itemStyle:{ normal: {color:'#669933'}}, } ], // links: [], links: [ {source:'BS ISO 16014-2:2019',target:'',lineStyle:''} ], lineStyle: { normal: { opacity: 0.9, width: 2, curveness: 0 } } } ] }; myChart.setOption(option);
