This standard JB/T 53048-1999 replaces JB/T 53048-92 and specifies quality grades, test methods, and sampling and evaluation procedures for corrugating machines. Products are classified into two grades: qualified and first-grade. Assessment items include corrugation quality, parallelism of corrugating roll axes, tooth surface roughness, service life, and working noise. First-grade products require automatic temperature control and thermal insulation of corrugating rolls. The standard applies to corrugating machines covered by JB/T 7542-1994, and was proposed by the National Packaging Standardization Technical Committee and drafted by Hefei General Machinery Research Institute.
本标准JB/T 53048-1999替代了JB/T 53048-92，规定了瓦楞机产品的质量等级、试验方法及抽样评定方法。产品分为合格品和一等品两个等级，考核项目包括瓦楞质量、瓦楞辊轴线平行度、齿面粗糙度、寿命和工作噪声等。一等品要求对瓦楞辊温度进行自动控制并隔热保温。标准适用于JB/T 7542-1994规定的瓦楞机产品，由全国包装标准化技术委员会归口，合肥通用机械研究所起草。

本标准规定了瓦楞机产品的质量等级，试验方法和抽样、评定方法。
瓦楞机产品根据其质量水平和使用价值分为合格品和一等品两个等级。
瓦楞机产品质量除符合JB/T 7542 规定外，各考核等级的项目指标及要求还应符合表1 及3.2 的规定。
评定产品质量等级，必须符合该等级全部考核项目的指标要求，或按达到的最低一项指标定等级。
一等品：对瓦楞辊温度进行自动控制并隔热保温。
This standard specifies the quality grades, test methods, and sampling and evaluation methods for corrugating machine products.
Corrugating machine products are divided into two grades: qualified product and first-grade product, based on their quality level and use value.
In addition to complying with JB/T 7542, the product quality of corrugating machines shall also meet the item indicators and requirements for each assessment grade as specified in Table 1 and clause 3.2.
When evaluating the product quality grade, it must meet the indicator requirements of all assessment items for that grade, or the grade shall be determined by the lowest indicator achieved.
First-grade product: automatic control and thermal insulation of corrugating roll temperature.
