ap(2004)5欧盟橡胶指令欧盟橡胶指令，官方名称为AP(2004)5号指令，是指为了保护消费者和环境安全而制定的指导性法规。

该指令从2004年开始实施，旨在限制和监管橡胶制品中含有的有害物质，以减少对人类和环境的危害。

本文将详细介绍欧盟橡胶指令的背景、主要内容和目标，并分析其对橡胶制品行业和相关利益方的影响。

指令的背景在过去的几十年中，随着工业和科技的发展，橡胶制品广泛应用于各个领域，如汽车制造、建筑和医疗领域。

然而，橡胶制品中含有的某些化学物质，如苯胺和致癌物质苯并(a)芘，对人类和环境可能会产生危害。

为了确保橡胶制品的安全性和环保性，欧盟决定制定橡胶指令进行监管。

指令的主要内容和目标欧盟橡胶指令的主要目标是限制和监管橡胶制品中的有害物质。

其中最重要的限制物质是苯胺类化合物和苯并(a)芘。

这些物质被认为对人类健康有潜在危害，并且在使用过程中可能会释放出来，对环境造成污染。

指令要求橡胶制品的生产商必须确保其产品不含超过法规规定限制值的有害物质。

生产商必须进行相关化学物质分析和测试，以确保产品符合欧盟标准。

同时，指令还规定了相关的测试方法和要求，以确保测试结果的准确性和可比性。

除了限制和监管有害物质，指令还对橡胶制品的标识和认证进行规范。

符合指令要求的产品必须标明相关的认证标志，以便消费者辨识和选择安全和环保的产品。

此外，指令还强调了生产商的责任和义务，要求他们提供相关的安全数据和技术文件，以便监管机构进行审查和验证。

指令对橡胶制品行业的影响欧盟橡胶指令的实施对橡胶制品行业有着重要的影响。

首先，该指令促使生产商对产品质量和安全性进行更加严格的控制和管理。

生产商必须加强对原材料和生产过程的监管，以确保产品不含有害物质，从而提高产品的质量和可靠性。

其次，指令推动了橡胶制品行业的技术创新和发展。

为了满足指令的要求，生产商需要不断改进产品设计和制造工艺，以减少有害物质的使用。

这将促进行业的创新和进步，加快替代有害物质的研发和应用。

Also refer toInternational Rectifier application notes AN1028 and AN1029 for further footprint design guidance.• Place as many vias around the Power pads (V IN , V SW , and P GND ) for both electrical and optimal thermalperformance.o Vias in between the different power pads may overlap the pad opening and solder mask edgewithout the need to plug the via hole. Vias with a 13mil drill hole and 25mil capture pad were used in this example.• A minimum of six 10µF, X5R, 16V ceramic capacitors per iP2004 are needed for greater than 25Aoperation. This will result in the lowest loss due to input capacitor ESR.• Placement of the ceramic input capacitors is critical to optimize switching performance. In cases wherethere is a heatsink on the case of iP2004, place all six ceramic capacitors right underneath the iP2004 footprint (see Bottom Component Layer). In cases where there is not heatsink, C1 and C6 on the bottom layer may be moved to the C1x and C6x locations (respectively) on the top component layer (see Top Component Layer).

BAT Battery voltage inputBAT is the battery voltage sense input,refer-enced to SNS.This is created by a high-impedance resistor-divider network con-nected between the positive and the negativeterminals of the battery.SNS Charging current sense inputSNS controls the switching of MOD based onan external sense resistor in the currentpath of the battery.SNS is the reference po-tential for both the TS and BAT pins.IfSNS is connected to V SS,then MOD switcheshigh at the beginning of charge and low atthe end of charge.LED1–LED2Charge status outputsPush-pull outputs indicating chargingstatus.See Table2.Vss GroundV CC V CC supply input5.0V,±10%power input.MOD Charge current control outputMOD is a push-pull output that is used tocontrol the charging current to the battery.MOD switches high to enable charging cur-rent to flow and low to inhibit chargingcurrent flow.DIS Discharge control outputPush-pull output used to control an externaltransistor to discharge the battery beforecharging.INH Charge inhibit inputWhen low,the bq2004E/H suspends allcharge actions,drives all outputs to high im-pedance,and assumes a low-power opera-tional state.When transitioning from low tohigh,a new charge cycle is started.2bq2004E/HFunctional DescriptionFigure2shows a block diagram and Figure3shows a state diagram of the bq2004E/H.Battery Voltage and Temperature MeasurementsBattery voltage and temperature are monitored for maximum allowable values.The voltage presented on the battery sense input,BAT,should represent a two-cell potential for the battery under charge.A resistor-divider ratio of:RB1 RB2=N2- 1is recommended to maintain the battery voltage within the valid range,where N is the number of cells,RB1is the resistor connected to the positive battery terminal, and RB2is the resistor connected to the negative bat-tery terminal.See Figure1.Note:This resistor-divider network input impedance to end-to-end should be at least200kΩand less than1MΩ.A ground-referenced negative temperature coefficient ther-mistor placed in proximity to the battery may be used as a low-cost temperature-to-voltage transducer.The tempera-ture sense voltage input at TS is developed using a resistor-thermistor network between V CC and V SS.See Figure1.Both the BAT and TS inputs are referenced to SNS,so the signals used inside the IC are:V BAT-V SNS=V CELLandV TS-V SNS=V TEMPDischarge-Before-ChargeThe DCMD input is used to command discharge-before-charge via the DIS output.Once activated,DIS becomes active (high) until V CELL falls below V EDV,at which time DIS goes low and a new fast charge cycle begins.The DCMD input is internally pulled up to V CC(its inac-tive state).Leaving the input unconnected,therefore, results in disabling discharge-before-charge.A negative going pulse on DCMD initiates discharge-before-charge at any time regardless of the current state of the bq2004.If DCMD is tied to V SS,discharge-before-charge will be the first step in all newly started charge cycles. Starting A Charge CycleA new charge cycle is started by:1.Application of V CC power.2.V CELL falling through the maximum cell voltage,V MCV where:V MCV= 0.8∗V CC±30mV3.A transition on the INH input from low to high.If DCMD is tied low,a discharge-before-charge will be executed as the first step of the new charge cycle.Oth-erwise,pre-charge qualification testing will be the first step.The battery must be within the configured temperature and voltage limits before fast charging begins.The valid battery voltage range is V EDV<V BAT<V MCV where:V EDV= 0.4∗V CC±30mV3bq2004E/HFigure 1.Voltage and Temperature MonitoringThe valid temperature range is V HTF <V TEMP <V LTF ,where:V LTF = 0.4∗V CC ±30mVV HTF = [(1/3∗V LTF ) + (2/3∗V TCO )]±30mVV TCO is the voltage presented at the TCO input pin,and is configured by the user with a resistor divider between V CC and ground.The allowed range is 0.2to 0.4∗V CC .If the temperature of the battery is out of range,or the voltage is too low ,the chip enters the charge pending state and waits for both conditions to fall within their al-lowed limits.During the charge-pending mode,the IC first applies a top-off charge to the battery .The top-off charge,at the rateof of the fast charge,continues until the fast-charge are met or the top-off time-out period is exceeded.The IC then trickle charges until the fast-charge conditions are met.There is no time limit on the charge pending state;the charger remains in this state as long as the voltage or tempera-ture conditons are outside of the allowed limits.If the voltage is too high,the chip goes to the battery absent state and waits until a new charge cycle is started.Fast charge continues until termination by one or more of the six possible termination conditions:n Delta temperature/delta time (∆T/∆t)n Peak voltage detection (PVD)n Negative delta voltage (-∆V)n Maximum voltage n Maximum temperature nMaximum timePVD and -∆V TerminationThe bq2004E/H samples the voltage at the BAT pin once every 34s.When -∆V termination is selected,if V CELL is lower than any previously measured value by 12mV ±4mV (6mV/cell),fast charge is terminated.When PVD termination is selected,if V CELL is lower than any previ-ously measured value by 6mV ±2mV (3mV/cell),fast charge is terminated.The PVD and -∆V tests are valid in the range 0.4∗V CC <V CELL <0.8∗V CC .4bq2004E/HFigure 2.Block Diagram5VSEL InputVoltage TerminationLow DisabledFloat -∆V HighPVDVoltage SamplingEach sample is an average of voltage measurements.The IC takes 32measurements in PVD mode and 16measurements in -∆V mode.The resulting sample peri-ods (9.17ms and 18.18ms,respectively)filter out har-monics centered around 55Hz and 109Hz.This tech-nique minimizes the effect of any AC line ripple that may feed through the power supply from either 50Hz or 60Hz AC sources.Tolerance on all timing is ±16%.Temperature and Voltage Termination Hold-offA hold-off period occurs at the start of fast charging.During the hold-off period,-∆V and ∆T/∆t termination are disabled.The MOD pin is enabled at a duty cycle of 260µs active for every 1820µs inactive.This modulation results in an average rate 1/8th that of the fast charge rate.This avoids premature termination on the voltage spikes sometimes produced by older batteries when fast-charge current is first applied.Maximum voltage and maximum temperature terminations are not af-fected by the hold-off period.∆T/∆t TerminationThe bq2004E/H samples at the voltage at the TS pin every 34s,and compares it to the value measured two samples earlier.If V TEMP has fallen 16mV ±4mV or more,fast charge is terminated.The ∆T/∆t termination test is valid only when V TCO <V TEMP <V LTF .Temperature SamplingEach sample is an average of 16voltage measurements.The resulting sample period (18.18ms)filters out har-monics around 55Hz.This technique minimizes the ef-fect of any AC line ripple that may feed through the power supply from either 50Hz or 60Hz AC sources.Tol-erance on all timing is ±16%.Maximum Voltage,Temperature,and TimeAnytime V CELL rises above V MCV ,the LEDs go off and cur-rent flow into the battery ceases immediately .If V CELL then falls back below V MCV before t MCV =1.5s ±0.5s,the chip transitions to the Charge Complete state (maximum voltage termination).If V CELL remains above V MCV at the expiration of t MCV ,the bq2004E/H transitions to the Bat-tery Absent state (battery removal).See Figure 3.Maximum temperature termination occurs anytime V TEMP falls below the temperature cutoff threshold V TCO .Charge will also be terminated if V TEMP rises above the low temperature fault threshold,V LTF ,after fast charge begins.Corresponding Fast-ChargeRate TM1TM2Typical Fast-Charge Safety Time (min)Typical PVD, -∆V Hold-Off

TM pin. Time settings are available for corresponding charge rates of C/4,C/2,1C,and2C.Maximum time-out termi-nation is enforced on the fast-charge phase,then reset, and enforced again on the top-off phase,if selected. There is no time limit on the trickle-charge phase.Top-off ChargeAn optional top-off charge phase may be selected to follow fast charge termination for the C/2through4C rates.This phase may be necessary on NiMH or other battery chemistries that have a tendency to terminate charge prior to reaching full capacity.With top-off en-abled,charging continues at a reduced rate after fast-charge termination for a period of time equal to 0.235∗the fast-charge safety time(See Table1.)Dur-ing top-off,the MOD pin is enabled at a duty cycle of 260µs active for every1820µs inactive.This modula-tion results in an average rate1/8th that of the fast charge rate.Maximum voltage,time,and temperature are the only termination methods enabled during top-off.Pulse-Trickle ChargePulse-trickle charging may be configured to follow the fast charge and optional top-off charge phases to com-pensate for self-discharge of the battery while it is idle in the charger.In the pulse-trickle mode,MOD is active for260µs of a period specified by the settings of TM1and TM2.See Table1.The resulting trickle-charge rate is C/512. Both pulse trickle and top-off may be disabled by tying TM1and TM2to V SS or by selecting Mode2in the dis-play.Charge Status IndicationCharge status is indicated by the LED1and LED2out-puts.The state of these outputs in the various charge cy-cle phases is given in Table2and illustrated in Figure3.In all cases,if V CELL exceeds the voltage at the MCV pin,both LED1and LED2outputs are held low regard-less of other conditions.Both can be used to directly drive an LED.Charge Current ControlThe bq2004E/H controls charge current through the MOD output pin.The current control circuitry is designed to sup-port implementation of a constant-current switching regulator or to gate an externally regulated current source.When used in switch mode configuration,the nominal regulated current is:I REG= 0.225V/R SNSCharge current is monitored at the SNS input by the voltage drop across a sense resistor,R SNS,between the low side of the battery pack and ground.R SNS is sized to provide the desired fast charge current.If the voltage at the SNS pin is less than V SNSLO,the MOD output is switched high to pass charge current to the battery.When the SNS voltage is greater than V SNSHI,the MOD output is switched low—shutting off charging current to the battery.V SNSLO= 0.04∗V CC±25mVV SNSHI= 0.05∗V CC±25mVWhen used to gate an externally regulated current source,the SNS pin is connected to V SS,and no sense re-sisitor is required.7bq2004E/Hbq2004E/HFigure 3.Charge Algorithm State Diagram8Absolute Maximum RatingsSymbol Parameter Minimum Maximum Unit NotesV CC V CC relative to V SS-0.3+7.0VV T DC voltage applied on any pin ex-cluding V CC relative to V SS-0.3+7.0VT OPR Operating ambient temperature-20+70°C CommercialT STG Storage temperature-55+125°CT SOLDER Soldering temperature-+260°C10 sec max.T BIAS Temperature under bias-40+85°CNote:Permanent device damage may occur if Absolute Maximum Ratings are exceeded.Functional opera-tion should be limited to the Recommended DC Operating Conditions detailed in this data sheet.Expo-sure to conditions beyond the operational limits for extended periods of time may affect device reliability.DC Thresholds(T A=T OPR;V CC±10%)Symbol Parameter Rating Tolerance Unit NotesV SNSHI High threshold at SNS result-ing in MOD = Low0.05*V CC±0.025VV SNSLO Low threshold at SNS result-ing in MOD = High0.04 * V CC ±0.025 VV LTF Low-temperature fault0.4*V CC±0.030V V TEMP ≥V LTF inhib-its/terminates charge V HTF High-temperature fault(1/3*V LTF) + (2/3*V TCO)±0.030V V TEMP≤V HTF inhibitschargeV EDV End-of-discharge voltage0.4*V CC±0.030V V CELL<V EDV inhibitsfast chargeV MCV Maximum cell voltage0.8*V CC±0.030V V CELL>V MCV inhibits/terminates chargeV THERM TS input change for∆T/∆tdetection-16±4mV V CC= 5V,T A= 25°C-∆V BAT input change for-∆Vdetection-12±4mV V CC= 5V,T A= 25°CPVD BAT input change for PVDdetection-6±2mV V CC= 5V,T A= 25°Cbq2004E/H9Recommended DC Operating Conditions(T A= T OPR)Symbol Condition Minimum Typical Maximum Unit NotesV CC Supply voltage 4.5 5.0 5.5VV BAT Battery input0-V CC VV CELL BAT voltage potential0-V CC V V BAT- V SNSV TS Thermistor input0-V CC VV TEMP TS voltage potential0-V CC V V TS- V SNSV TCO Temperature cutoff0.2*V CC-0.4*V CC V Valid∆T/∆t rangeV IHLogic input high 2.0--V DCMD,INHLogic input high V CC- 0.3--V TM1, TM2, DSEL, VSEL V ILLogic input low--0.8V DCMD,INHLogic input low--0.3V TM1, TM2, DSEL, VSELV OH Logic output high V CC- 0.8--V DIS, MOD, LED1, LED2,I OH≤-10mAV OL Logic output low--0.8V DIS,MOD,LED1,LED2,I OL≤10mAI CC Supply current-13mA Outputs unloadedI SB Standby current--1µA INH= V ILI OH DIS,LED1,LED2,MOD source-10--mA@V OH= V CC- 0.8VI OL DIS,LED1,LED2,MOD sink10--mA@V OL= V SS+ 0.8VI LInput leakage--±1µA INH, BAT, V = V SS to V CC Input leakage50-400µA DCMD, V = V SS to V CCI IL Logic input low source--70µA TM1, TM2, DSEL, VSEL,V = V SS to V SS+ 0.3VI IH Logic input high source-70--µA TM1, TM2, DSEL, VSEL,V = V CC- 0.3V to V CCI IZ Tri-state-2-2µA TM1,TM2,DSEL,and VSEL should be left disconnected (floating)for Z logic input stateNote:All voltages relative to V SS except as noted. bq2004E/H10分销商库存信息:TIBQ2004EPN BQ2004HPN BQ2004ESNTR BQ2004HSN BQ2004ESN BQ2004ESNTRG4 BQ2004HSNTR BQ2004HSNTRG4BQ2004EPNG4 BQ2004ESNG4。

因此，现阶段适用于所有食品接触橡胶制品的欧盟法规是欧盟出台的框架性法规和针对具体物质的指令。

任何进口到欧盟的食品接触橡胶制品必须遵循框架性法规中的通用要求以及指令中涉及橡胶制品所用物质的安全卫生要求。

1、（EC）No 1935/2004 法令通用安全规范要求（EC）No 1935/2004 法令《关于拟与食品接触的材料和制品暨废除80/590/EEC 和89/109/EEC 指令》于2004 年底取代早期实施的框架性指令89/109/EEC 及80/590/EEC 而成为欧盟新的食品接触材料框架性条例，由于法规是以法令（Regulation）形式颁布，意味着各成员国无需进行任何转换，而必须直接完整地接受和遵守执行。

因此从某种意义上可以说其法律效力更强。

（1）适用范围和对象No 1935/2004 条例适用范围包括所有预期或可能与食品接触的材料及制品（其中包括：打印油墨、胶标签）。

但是，它不适用于那些作为古董用途的材料及制品以及构成食品的一部分并可以被直接食用的覆盖层或涂料、涂层（如糖衣、肠衣等）制品。

此外，用于公共及消费者用水供应系统的材料及制品也不在该指令的适用范围内，而受另行制定的专门条例管辖。

（2）通用要求作为框架性的条例，它规定了适用于所有食品接触材料的总原则和规定，内容包括适用范围、通用安全要求，活性、职能包装，新物质授权的申请，标签，符合性声明，可追溯性，安全措施等28 个条款。

条例的核心条款是规定了所有食品接触材料必须满足的通用要求：A 食品接触材料和制品，包括活性和智能材料和制品，其生产应符合良好生产规范，从而在正常或可预见的使用条件，其成分向食品的迁移总量不致造成：●危害人体健康；●导致食品成分发生不能接受的变化；●降低食品所特有的感官特性（使食品的味道，气味，颜色等改变）；B 食品接触材料和制品的标签、广告以及说明不应误导消费者。
