12/16/2023 0 Comments Point to point measure![]() At a certain temperature we can detect that condensation has started to form, meaning the surface temperature of the pipe has dropped to the point where the surrounding air is no longer able to hold the humidity in gaseous form. When you turn on the shower, the flow of cold water begins to lower the surface temperature of the pipe and cool the air around it. Let’s assume that your bathroom is at 50%RH with a temperature of 21☌. If the hot and cold pipes in your shower aren’t insulated, you may have noticed that water droplets form on the surface of the cold pipe. This is the temperature to which air must be cooled to become saturated with water vapor, and one easy way to understand this phenomenon is to think about taking a shower. An easy method is to measure a retail sample and use the specs from it as a base line to determine your own specs.Following on from our previous post on relative humidity (RH), let’s look at the second most commonly used humidity parameter – dew point temperature. If you’re wondering how to determine your base size specs, we won’t be covering that in this series. The grade will automatically calculate if you used the VLOOKUP formula. The POM you created in step 1 should automatically appear if you used the VLOOKUP formula.Įnter your base size specs for each of your POM’s. Use the VLOOKUP formula from Section 1 of this series to link your POM list to your Graded Spec page.Īdd your POM identifier / code to the appropriate column. Input the grade as a +/- in comparison to the base size. Be sure to give each POM it’s own unique code (number).Īdd the tolerance appropriate for each POM.Īdd your size range and determine your grade using the information from Section 3 of this series. HOW TO SET UP YOUR POM & GRADED SPEC PAGESĬreate your POM’s using the formula above. The POM and Graded Spec section starts at 02:20: For information on how I set up the graded spec page and the POM page template in the tech pack, head to Section 1 of this series. Those POM’s can then be added to your Graded Spec Page with your specific garment measurements. #004 - WAIST WIDTH (1/2 MEASURE): MEASURE WIDTH FROM SIDE TO SIDE AT WAIST.Īs I said before, your POM page will house all of your POM’s, your tolerance, and your grade. You always want to clearly define the type of measurement, location, and starting and stopping point when writing POM descriptions. ![]() Here’s my fool-proof formula for writing POM descriptions. When you review your sample, if the measurements fall outside of that tolerance you can reject the sample or tell the factory to go back to spec (BTS) for the next sample. For example, your tolerance for sleeve length may be +/- 1/2” meaning you are willing to accept a sample that falls 1/2” above or below the spec you requested. Your tolerance for prototyping is typically more strict than your tolerance for production. Tolerance is the amount you are willing to accept POM’s off of spec. Your POM numbers also correspond to your How To Measure Guide where you and your factory can reference your brands standards for how to measure your garments. Not only that, but POM codes act as a shorthand identifier for prototype review comments. The function will pull all of the information from your POM library and automatically calculate your graded specs for your size run, simply by adding the POM code on the Graded Spec page. POM numbers allow you to quickly fill out your POM’s on your Graded Spec page in the Tech Pack using the VLOOKUP function I teach in section 1. Using your POM library you can include POM’s specific to the style to create the spec page for the development of your garment. The Graded Spec page is where you will spec your garment for your full size run. It’s important to create a clear standard with your factory by having a corresponding How to Measure Guide that illustrates how to measure each point. On this page you will also include the tolerance for each point and the grade for your brand. The POM page is a library where you will house your standards for speccing your garment. Let’s remind ourselves what the Points of Measure page in our Tech Pack is. Learn what tolerance is and how to determine tolerance for your unique POM’sĬreate your very own How to Measure Guide Use POM codes and my fool-proof formula to develop your own POM library Set up a POM page in the Tech Pack and use it to spec your garment Here’s what you’ll learn in this section: Hey guys, welcome back! Here in Section 5 we are going to be diving into Points of Measure.
