In addition, we use a high level of training of our personnel in the use of the tools and methodology so we can achieve these low PPM rates. To control our defective rate, Xmultiple uses a systematic and scientific approach to design and manufacturing in our facility. It is the result of careful planning, design, and execution. Quality can not be inspected in after the fact.
We can now control the process in order to control the quality. The monitoring and measurement systems we have today have paved the way for improved quality. One bad part for the entire plant for 24 hours! This is what Xmultiple has achieved and we meet our customers expections for the lowest possible defective rates. Or to put it another way, one bad part per day! In this example we did not say one bad part per day per person or job, or shift or machine. That means that the manufacturer would be allowed 25 pieces for every 1, pieces or defective parts per year. Let's assume most customers requirements are 25 PPM. The manufacturers plant operates around 5 days a week, 50 weeks per year or days a year in most cases. Let's say, a manufacturer produces 10, parts per year for their customer. How to calculate PPM is best explained in an example. To calculate: For example, if you had 25 pieces defective in a shipment of 1, pieces. Now the rate for most connectors and components is targeted at 25 PPM or 0. However, production and quality control procedures have improved and expectation was increased to 0. PPM Parts per million is a measurement used by many customers to measure quality performance. Copyright Leaf Group Ltd.Xmultiple's Engineering Department.

Just remember that you need to keep the same units, and the process is simple.
Then you can use the following formula to find the concentration. In general, though, you can always calculate PPM using one approach and a simple formula. Another easy example is a rare case when you can easily mix masses and volumes and convert to PPM. To perform the conversion, then, simply multiply the value in percent by 10, or 10 4. One of these is the conversion from a percentage value to a PPM value because 1 PPM is just 10, times bigger than one percent. There are a couple of situations where a PPM calculation is very easy to do.
In the same way you might say you have a 7 percent solution, you might say that you have a 36 PPM solution.
