The difference between gb1615 standard and gb1613 for industrial rubber sheet
At present, the GB5574-85 standard has been eliminated, the latest standard for industrial rubber sheet is GB/T5574-2008, and the method of rubber plate in GB/T5574-2008 is:Section 1: oil resistance, A- is not resistant to oil, B- medium oil resistance, C- oil resistance;Second section: nominal value of tensile strength of rubber sheet, unit MPaThird section: elongation at break. Near elongation at /100.Fourth section: rubber board hardness /10, add H letter.
Industrial rubber sheet 1615 and 1613 are industrial rubber sheet national standard GB5574-85, the following different rubber plate code, the GB has a lot of code below, specific each code name means as follows:First: rubber plate type: 1 - ordinary rubber plate, 2 - acid alkali rubber plate, 3 - oil resistant rubber plate, 4 - heat resistant rubber sheet.Second: rubber sheet hardness 10 figures, such as 4604 rubber sheet hardness code is 6, hardness is 60 + 5, Shao degrees.Third, fourth: rubber sheet tensile strength, such as 4604 rubber sheet, three or four place is 04, tensile strength is 4Mpa.
The difference is as follows:1615 rubber sheet is a common rubber sheet with a hardness of 60 and a tensile strength of 15Mpa.1613 rubber sheet is a common rubber sheet with a hardness of 60 and a tensile strength of 13Mpa.
