ISA (International Society of Automation) tolerance system is used to specify the acceptable variations in dimensions and fits for mechanical parts. It consists of a combination of numbers that represent the qualities of tolerance and grades of fit. These numbers are used to determine the acceptable range of dimensions and fits for different types of applications.
The correct answer to the question is option 'D', which indicates that the ISA tolerance system consists of 16 qualities of tolerance and 21 grades of fit. Let's understand what these numbers mean in the context of the ISA tolerance system.
1. Qualities of Tolerance:
The qualities of tolerance in the ISA system represent the degree of variation allowed in a dimension. These qualities are indicated by numbers ranging from 1 to 45, with each number representing a specific quality of tolerance. The higher the number, the greater the tolerance allowed. In this case, the system consists of 16 qualities of tolerance.
2. Grades of Fit:
The grades of fit in the ISA system represent the acceptable range of clearances or interference between mating parts. These grades are indicated by numbers ranging from 1 to 99, with each number representing a specific grade of fit. The lower the number, the tighter the fit, and the higher the number, the looser the fit. In this case, the system consists of 21 grades of fit.
The combination of these qualities of tolerance and grades of fit allows engineers and manufacturers to specify the acceptable range of dimensions and fits for different types of applications. For example, a tight fit may be required for precision instruments, while a looser fit may be acceptable for general-purpose machinery.
In conclusion, the ISA tolerance system consists of 16 qualities of tolerance and 21 grades of fit. These numbers represent the acceptable variations in dimensions and fits for different types of applications. It is important for engineers and manufacturers to understand and apply this system correctly to ensure the desired level of precision and functionality in mechanical parts.
