W.S.Tyler测试筛网
W.S.泰勒早在逾100年前就奠定了试验筛标准的基础。可重复的试验结果以及来自实验室的粒度分布曲线对于质量控制方案而言具有极其重要的意义。
试验筛网和试验筛均是按照所有适用标准进行制造，并受到健全的质量管理体系的监督。除非另有约定，提供的所有试验筛均会附带一份免费的合规证书。
W.S.Tyler提供三种等级的测试筛：
标准型：附带合规证书。等同于ASTME11合规筛网。
认证：附带NIST可追溯直方图。等同于ASTME11检验筛网。更多信息请参见筛分分析与校准部分。
认证-PLUS：附带NIST可追溯直方图。等同于ASTME11校准筛网。详见第35页的筛分分析与校准部分以获取更多信息。
测试筛分信息/指南
有关具体规格的信息，请参考标准ASTME11和ISO565、3310-1。
