1.1本规程涵盖有涂层和无涂层机织平织物和单件机织物（OPW）的检查和分级程序，以及由此类织物制成的切割件的检查和挑选程序，所有这些都用于制造安全气囊垫。 1.2为便于参考，各检验规程的范围、实践总结、意义和用途、仪器、取样、程序和报告章节分别列出。 检验实践 部分 织物卷 7. 切割件 & OPW公司 8. 1.3这些做法可用于区分可能对安全气囊袋制造或性能产生不利影响的织物缺陷和不会产生不利影响的织物缺陷。 1.4经买方和供应商同意，可使用本规程中规定以外的程序和仪器，并在报告中确认与本规程的具体偏差。 1.5以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 这些做法适合纳入规范。本规范中提及的材料或座垫规格应指买方和供应商之间就安全气囊用织物的检查和验收达成的任何类似协议。 这些规程包括术语、条件、设备和程序，通过这些术语、条件、设备和程序对安全气囊织物卷或切割件进行检查和分级。 考虑到织物性能、材料处理设备或安全气囊设计或其组合，包含这些实践的规范可能会偏离这些规范。 每当出现此类偏离标准的情况时，都会将其记录在报告中。 这些做法承认，在正常生产过程中，将生产出含有缺陷的可接受的织物卷；随后，将从轧辊上切割工件，并在那时剔除表1-5中限制的缺陷。 使用这些方法目视检查织物结果的准确性受到检查员检测、识别和评估移动织物或切割部分缺陷严重程度的能力的影响。 这种能力可能受到视力、观察距离、织物横移速度、照明条件、检查员纪律和培训以及合适视觉辅助工具的可用性和准确性的影响。 当用于识别和量化缺陷的视觉辅助工具的精度或比例在买方和供应商之间不同时，使用这些实践可能会导致系统性偏差。

1.1 These practices cover procedures for the inspection and grading of coated and uncoated woven flat and one-piece woven (OPW) fabrics, and for the inspection and culling of cut parts made of such fabrics, all of which are used in the manufacture of inflatable restraint cushions. 1.2 For ease of reference, the scope, summary of practice, significance and use, apparatus, sampling, procedure, and report sections are listed separately for each inspection practice. Inspection Practice Section Fabric Rolls 7 Cut Pieces & OPW 8 1.3 These practices can be used to distinguish those fabric imperfections that may adversely affect inflatable restraint cushion fabrication or performance from those imperfections that will not. 1.4 Procedures and apparatus other than those stated in these practices may be used by agreement of the purchaser and supplier with the specific deviations from these practices acknowledged in the report. 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. ====== Significance And Use ====== These practices are suitable for incorporation in a specification. Any reference to material or cushion specification in these practices shall mean any similar agreement between the purchaser and supplier relating to the inspection and acceptance of fabric intended for inflatable restraint use. These practices constitute the terminology, conditions, equipment, and procedures by which rolls of inflatable restraint fabrics or cut parts are inspected and graded. A specification incorporating these practices may deviate from them to account for considerations of fabric property, material handling equipment, or inflatable restraint cushion design, or a combination thereof. Whenever such deviations from standard occur, they are recorded in the report. These practices acknowledge that, in the normal course of production, acceptable rolls of fabric will be produced containing imperfections; subsequently, pieces will be cut from the rolls and those pieces that contain imperfections restricted in Tables 1-5 will be culled at that time. The accuracy in the results from visually inspecting fabric using these practices is affected by the ability of the inspector to detect, identify, and evaluate the severity of an imperfection in a moving fabric or in a cut part. Such ability can be affected by visual acuity, viewing distance, fabric traverse speed, lighting conditions, inspector discipline and training, and the availability and accuracy of suitable visual aids. Systematic bias may result from using these practices whenever the precision or scale of the visual aids used to identify and quantify imperfections differs between the purchaser and supplier.
