Product Code:SAE J2003 Title:Internal Combustion Engines--Piston Rings Coil Spring Loaded Oil Control Rings (Cancelled Jun 2008) Issuing Committee:Piston And Ring Standards Committee Scope:This SAE Standard is equivalent to ISO Standard 6626.Differences, where they exist, are shown in the appendix with associated rationale.This document specifies the essential dimensions of piston ring types DSF-C, DSF-CNP, SSF, GSF, DSF, DSF-NG, and SSF-L coil spring loaded oil control rings.For the cast iron part the recommended material is class 10 according to SAE J1590. For special applications material classes 20 to 50 may be used.Variation in face design and spring groove from these may be used, as recommended by individual manufacturers, in plain or chromed versions.The tangential forces of coil spring loaded oil control rings can be varied over a wide range. Explanations and recommendations are given in Section 6.The normal range for axial width of coil spring loaded oil control rings (3 to 8 mm inclusive) is divided into 0.5 or 1.0 mm steps. In Tables 9 to 14 dimensions are given for coil spring loaded oil control rings within an axial width of 4.75 mm (i.e., 3/16 in) for existing applications in inch units.This document applies to coil spring loaded oil control rings up to 200 mm inclusive for reciprocating internal combustion engines. It may also be used for piston rings of compressors working under similar conditions.【英文标准名称】:Plastics-RecycledPlastics-CharacterisationofPolypropylene(PP)recyclates;EnglishversionofDINEN15345:2008-02 【原文标准名称】:塑料.回收的塑料.聚丙烯(PP)回收材料的特征 【标准号】:EN15345-2007 【标准状态】:现行 【国别】: 【发布日期】:2008-02 【实施或试行日期】: 【发布单位】:欧洲标准学会(EN) 【起草单位】: 【标准类型】:() 【标准水平】:() 【中文主题词】:松散材料密度;特征;收费;组分;交付;测定规程;评定;均聚物;测量;测量技术;塑料;塑料加工;聚丙烯;特性;质量保证;质量控制;回收材料;再循环;试样;抽样方法;卖货商;测试;热塑性聚合物 【英文主题词】:Bulkdensity;Characterisations;Charge;Composition;Delivery;Determinationprocedures;Evaluations;Homopolymers;Measurement;Measuringtechniques;Plastics;Plasticsprocessings;Polypropylene;PP;Properties;Qualityassurance;Qualitycontrol;Recyclates;Recycling;Samples;Samplingmethods;Sellers;Testing;Thermoplasticpolymers 【摘要】: 【中国标准分类号】:G32 【国际标准分类号】:13_030_50;83_080_20 【页数】:14P.;A4 【正文语种】:英语
