Post by: Kent Longardner, Technical Sales Manager Have you ever wondered about about the impact of lumber's dimensional accuracy on wooden pallets and crates? Have your own wrong-size lumber story? Talk to me in the comments below. The next big step in moving the new procedures forward is expected by summer 2018 when the proposal goes to a vote. The Office of Weights and Measures (OWM) at the NIST has been working with the American Lumber Standards Committee (ALSC) since 2016 to develop new testing procedures for dimensional accuracy. As an example, a 6 inch hardwood board is actually 5.5". If you're wondering about hardwoods, thickness measurements are slightly different, but most hardwood widths follow the softwood standard. Everything from an individual inspector's sampling protocol to the device used for measuring can muddy the results. Inspectors do not have nationally agreed-upon testing procedures. The ISO paper sizes standard overview of ISO 216:2007 have more paper formats such as A1, A2, A3, A4, A5, A6, and more. A0 paper size is the largest size in the ISO A-Series. The designation stands for "surfaced 4 sides". The sizes of paper range from A0, the core with the dimensions 841 by 1189 mm (33.1 by 46.8 inches). Dimensional lumber is commonly labeled S4S. A 2020 research article notes that most males believe the average length of an erect penis is around 15.2 centimeters (cm) or 6 inches (in). The process of smoothing out board surfaces further reduces the original width or thickness. This equals anywhere from 0.012” to 0.6" for a 4 inch board.īoards with smooth sides are said to have a dressed surfaced. Depending on wood species - and specifically wood grain direction - shrinkage can range from 2% to 15%. As the wood dries (either in an oven or air dried) the dimensions reduce. Green lumber has higher moisture content. State and local inspectors spot check lumber dimensions at mills and retail locations but determining if softwood boards are within limits is complicated. Fittings follow this same pattern, a 1' fitting has a 1.315 inch opening to accept a 1 inch pipe, which actually measures 1.315 inches in diameter. How long is 3 inches How far is 3 inches in centimeters This simple calculator will allow you to easily convert 3 in to cm. For example, a 1 inch PVC Pipe is actually 1.315 inches in outside diameter, and 1.029 inches in inside diameter. The latest version is labeled the Voluntary Product Standard PS 20-15. PVC Pipe sizes are different than the size the pipe is called. The current standards are published by the government in a document titled the American Softwood Lumber Standard (PS 20). ![]() Today, regulating dimensional accuracy in the US falls under the responsibility of the National Institute of Standards and Technology (NIST). The US Department of Commerce standardized softwood dimensions for green and finished lumber back in 1969.
