从国家监督抽查公布的结果表明,烧结普通砖产品质量极差,如1992年全国抽查95家砖厂的产品质量,结果是合格率只有17.9%,1993年全国抽查107家砖厂,合格率也只有28%.这充分说明砖瓦企业需要在执行国家标准,狠抓产品质量上下功夫,以保证国家基本建设的需要.烧结普通砖国家标准是强制性标准,根据标准化法,强制性标准企业必须贯彻执行.目前执行的GB5101一85《烧结普通砖》国家标准,已经过认真修订并通过审议,新国际GB5101—93将于1994年7月1日实施.新国标在尺寸偏差、强度等级,抗风化性能等方面都提出了新的试验方法和检验规则,产品质量的分等也有变化.在目前烧结普通砖的产品质量极差的现状下,更有必要充分做好执行新国标的准备工作.
The results from the national supervision and random inspection showed that the quality of sintered ordinary brick products is extremely poor. For example, in 1992, the quality of products of 95 brick factories across the country was checked. The result was that the pass rate was only 17.9%. In 1993, 107 brick factories were sampled across the country, and the passing rate was also Only 28%. This fully shows that brick and tile companies need to implement national standards, pay close attention to product quality and work hard to ensure the national infrastructure needs. Sintered ordinary brick national standards are mandatory standards, according to the standardization law, mandatory standards must be Implemented. The currently implemented GB5101-85 “Sintered Ordinary Brick” national standard has been carefully revised and passed. The new international GB5101-93 will be implemented on July 1, 1994. The new national standard is in size deviation, strength grade, resistance Weathering performance and other aspects have proposed new test methods and inspection rules, product quality classification has also changed. In the current situation of poor quality of sintered ordinary brick products, it is more necessary to fully prepare for the implementation of the new national standard.
