摘　　要：依据GB/T 2910.1—2009、GB/T 2910.6—2009和SN/T 3315.4—2012,采用甲酸/氯化锌法、60%硫酸法和手工拆分法对C/CVP交织物进行定量分析比较试验。依据CNAS-TRL-002:2020和JJF 1059.1—2012,详细分析3种试验方法条件下测量不确定度之间的差异。结果表明,60%硫酸法的精密度要优于甲酸/氯化锌法,3种试验方法结果的不确定度之间存在差异,甲酸/氯化锌法的准确度要优于60%硫酸法,影响测量结果的主要来源是操作复现性引入的不确定度分量(A类)。According to GB/T 2910.1—2009,GB/T 2910.6—2009,and SN/T 3315.4—2012,the quantitative analy-sis and comparative experiments of C/CVP interwoven fabrics are carried out by the formic acid/zinc chloride method,the 60%sulfuric acid method,and the manual separation method.The differences in measurement uncertainty under the three experimental procedures are thoroughly examined according to CNAS-TRL-002:2020 and JJF 1059.1—2012.The results show that the precision of 60%sulfuric acid method is better than that of formic acid/zinc chloride method.The uncertain-ty of the three experimental procedures differs,and the formic acid/zinc chloride method is more accurate than the 60%sulfuric acid method.The uncertainty component(class A)introduced by operational reproducibility is the principal source influencing measurement data.
