密度是水处理剂类产品的一个重要的质量指标。现行有效的GB/T22594-2008是这类产品密度测定的一个通用标准。根据密度瓶法测定液体密度的原理,确证了该标准的密度瓶法计算公式的相关表述存在问题,并对此问题进行了深入地分析,提出了针对此标准密度瓶法的可操作性修改建议。目的在于提醒标准的使用者正确使用该标准,敦促标准的管理方尽快修订该标准。
Density is an important quality indicator for water treatment chemicals. The currently valid GB / T22594-2008 is a common standard for the densitometry of such products. According to the principle of measuring the density of liquid by the density bottle method, the problems existing in the expression of the standard density bottle method are confirmed, and the problems are analyzed in depth. The suggestions of operability modification for the standard density bottle method are put forward . The purpose is to remind standard users to use the standard correctly and urge the standard administrator to amend the standard as soon as possible.
