4.1 It is possible that insulating blocks or boards that are not true or square will not fit properly. It is possible that extra labor will be required to obtain proper fit and that this could affect the product performance as well as the appearance of the finished installation.4.2 This test method provides terminology and describes locations for obtaining consistent measurements of trueness and squareness of blocks and boards.1.1 This test method covers locations for measuring the trueness and squareness of rigid block/board thermal insulation. This test method does not purport to address the variability in board thickness. Thickness is addressed in other ASTM standards.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

2.1 This guide covers the calibration of row, band, and broadcast applicators. Attainment of accurate and more uniform application can reduce the quantity of active ingredient required for a given degree of control, thus improving environmental quality and safety at a more economical cost. A single-calibration procedure applicable in all situations is not feasible because of the nature of the variables involved in chemical applications.1.1 This guide is for those who prepare granular pesticide ground applicator calibration procedures. The purpose is to encourage methods that will improve uniformity and accuracy of application with granular applicators.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements see Section 4.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
