ISO 2145 is a special type of paper used for writing and printing technical documents like manuals or engineering plans. Imagine you're playing with your favorite toy and you want to draw a picture of it to show your friends how to play with it. You need paper to draw on, right? But not all paper is the same. Some paper is thicker or thinner, some is smoother or rougher.
ISO 2145 is a type of paper that has specific properties to make it ideal for technical documents. It's usually white, and it's designed to be strong and durable so it doesn't tear easily. It's also has a smooth surface which makes it easier to write on and print on.
When people write or print on this paper, they can use special symbols and numbers to organize the information. This makes it easier for people who read the document to understand it. For example, if you were writing a manual about how to put together a toy car, you might use symbols to show which pieces connect to each other, and you might include numbers to show the order in which the pieces should be assembled.
So, to sum it up, ISO 2145 is a type of paper specially designed for technical documents that is strong, smooth, and organized with symbols and numbers to make them easier to understand. It's like the perfect paper for all your engineering and technical needs.
