3.1 This guide is not intended to be all-inclusive. There may be additional aspects of performance and safety that need to be addressed in order to have a comprehensive study of the subject matter.3.2 The suggested preliminary guideline summaries that follow were developed by a consensus of bowhunters with many years of field experience, industry people with knowledge in the design and manufacture of broadheads, and individuals experienced in the distribution and retail areas of the business who have close contact with end users.1.1 This guide covers the formulation of preliminary guidelines in six areas of broadhead performance and safety.1.2 The first three guidelines, flight, penetration, and sharpness, are related to performance, but they can have some bearing on safety. The last three, impact resistance, assembly and attachment methods, and packaging, determine to a great degree the safety level of the broadhead in the hands of the end user.1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.

5.1 This test method is considered satisfactory for quality control testing.5.2 If there are differences of practical significance between reported test results for two laboratories, comparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, use test samples as homogeneous as possible, drawn from the material from which the disparate test results were obtained, and randomly assigned in equal number to each laboratory for testing. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If a bias is found, either its cause must be found and corrected, or future results for the source material must be adjusted in consideration of the known bias.5.3 The stiffness of fabric relates to its resistance to bending with further processing and use. It measures the fiber and yarn bending capabilities, the cohesion of individual fibers and yarns relative to their displacement and binders or finishes that hold them in place.1.1 This test method covers the determination of the stiffness of fabrics by measuring the force required to push a specimen into a slot of predetermined width with a metal blade working at a predetermined capacity.NOTE 1: For other methods for testing stiffness, refer to Test Methods D1388, D4032, and D5732.1.2 This test method is applicable to fabrics of any fiber content whose stiffness does not exceed the capacity of the Penetrator Beam apparatus. Specimens can be taken from fabrics, rolls, or end products.1.3 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.1.4 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.1.5 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.

5.1 By following this practice it is possible to make reproducible flushes when using the same raw materials. Therefore, if someone wishes to evaluate the effect a different raw material has on a flush, it is possible to evaluate this effect by noting the change that occurs from a control flush to the experimental flush. This change can be, but is not limited to; such things as strength after vacuum, grind, grit, gloss etc. This practice can be used by ink companies, pigment companies or varnish companies. This practice is not meant to give absolute values but is meant to be used as a relative practice in which a control flush is made using a standard formula and the experimental flush is compared to the control flush. This practice is not meant to determine the absolute performance of a formula in production. Again it can be used to give a relative idea of how a formula will perform in production when a correlation has been established between laboratory flushing and production flushing.1.1 This practice covers guidelines for the evaluations of flushing vehicles for pigment dispersion using a vacuum modified sigma blade mixer, or vacuum flusher.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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.
