(Practice)Standard Practice for Manufacturing Quality Control of Consumer Trampoline Bed Material
Standard Practice for Manufacturing Quality Control of Consumer Trampoline Bed Material
SIGNIFICANCE AND USE
CTM must be properly manufactured in a manner consistent with a minimum level of quality control as determined by in-house testing of the final product. This practice suggest types of tests, the methods of the testing and the minimum testing frequencies.
It should be clearly recognized that manufacturers may perform additional tests or at a greater frequency than required in this practice, or both. In this case the manufacturer’s quality control plan will take precedence over this practice. The quoted tests and test methods in Table 1 must appear in the QC plan and QC report.
It should also be recognized that purchasers and installers of CTM may require additional tests or a greater frequency than called for in this practice or both. The organization(s) producing such project specific specification or quality assurance plan should recognize that such requirements are beyond the current state of the practice. If such a request is made by the purchasers or installers, they should clearly communicate the requirements to the manufacturer or supplier during the contract decisions in order that disputes do not arise at a subsequent time.
This practice provides a means by which samples of CTM may be selected to provide a statistically valid sample for selection of test specimens without previous knowledge of the variability that may exist between production units.
The principles stated in Practice D4271, and the illustrative text in that practice can be used by the test method authors in preparing sampling statements.
SCOPE
1.1 This practice covers the manufacturing quality control of Consumer Trampoline-Bed Material (CTM), describing types of tests, the proper test methods, minimum testing frequencies, and best practices for sampling.
1.2 This practice is intended to aid manufacturers, suppliers, purchasers, installers, and end users of CTM in establishing a minimum level of effort for maintaining quality control.
1.3 This practice does not address manufacturing quality assurance, product acceptance testing, or conformance testing. These are independent activities taken by organizations other than the CTM manufacturer.
1.4 This practice covers procedures for sampling CTM for the purpose of manufacturing quality control (MQC). These procedures are designed to ensure the correct number of representative samples are obtained and properly reported by the manufacturer.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.6 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.
