Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.

With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers the physical dimensions and characteristics of a laboratory burner used for small-scale burning tests on plastic materials, with the supply gases including methane, propane, and butane. The burner shall consist of a burner barrel that threads onto a one-piece base, which is equipped with an orifice and a needle valve that restricts the orifice opening and regulates the gas velocity through the burner, and a gas inlet, which consists of a serrated fitting for connection to the gas supply. A lock nut for securing the barrel onto the base may be provided optionally. The mixing tube of the barrel shall be manufactured with a uniform bore, and the barrel, threads, and serrated fitting shall be free of flash and burrs.
