1. 范围1.1这个规范涵盖了以下五个试验：1.1.1试验A——奥氏体不锈钢的腐蚀结构分类的草酸腐蚀试验（包括从第3节到第7节）1.1.2试验B——检测奥氏体不锈钢晶间腐蚀敏感度的硫酸铁-硫酸试验（包括从第8节到第14节）1.1.3试验C——检测奥氏体不锈钢晶间腐蚀敏感度的硝酸试验（包括从第15节到第21节）1.1.4试验E——检测奥氏体不锈钢晶间腐蚀敏感度的铜-硫酸铜-硫酸试验（包括从第22节到第31节）1.1.5试验F——检测奥氏体不锈钢晶间腐蚀敏感度的铜-硫酸铜-50%硫酸试验（包括从第32节到第38节）1.2以下因素制约制约着这个规范：1.2.1所有的六个检测都要检测碳铬化物晶间腐蚀感度1.2.2铬镍钼钢中的σ相在硝酸中可导致高腐蚀速率，σ相在微观结构中也不一定可见。

1.2.3在钛或铌合金和钼合金轴承钢中的σ相在硝酸和硫酸铁-硫酸溶液中会有高腐蚀速率，铸铁轴承不锈钢合金，这种σ相在微观结构中也不一定可见。

1.3草酸腐蚀试验是一种快速的确定不锈钢试样的等级方法，这种牌号的不锈钢不会产生碳铬化合物的晶间腐蚀。

在特定的腐蚀测试条件下，这种试样腐蚀速率低，因此可以从实验中排除看是否可接受的。

1.4硫酸铁-硫酸试验，铜-硫酸铜-50％硫酸的试验，以及硝酸测试这些实验以重量减少为基础，从而为相关的试样评估提供了一个定量方法。

相反，铜-硫酸铜-16％硫酸试验主要对弯曲试样进行表观检查，因此只能确定试样是否合格。

Important safety informationHMEC 26-2 | 1Important safety information̈Please read this instruction manual carefully and completely before using the product.̈Always include this instruction manual when passing the product on to third parties.̈This instruction manual is also available on the Internet at or .Preventing health problems and accidents̈Always maintain a distance of at least 3.94“ (10 cm) between the ear cups and the cardiac pacemaker or implanted defibrillator since the product generates permanent magnetic fields.̈Keep product, accessory and packaging parts out of reach of children who could swallow smaller pieces.̈Switch the product off after use to conserve battery power. Remove the rechargeable batteries if the product will not be used for extended periods of time.̈If during flight operation you, as the pilot, operate your connected device using the headset, this can limit your attention. During flight operation, do not use the headset for making phone calls or listening to music.̈With the NoiseGard TM noise compensation switched on, typical aircraft sounds (for example, those from engines, propellers, warning alarms, etc.) may sound different to you. Before operating any aircraft, make sure that, withImportant safety information2 | HMEC 26-2NoiseGard TM switched on, you can hear and recognize these sounds. Set the volume to safe levels that do not interfere with your ability to hear informational sounds and warning alarms.̈The product is capable of producing sound pressure exceeding 85 dB(A). In many countries 85 dB(A) is the maximum legally permissible level for continuous noise exposure during the working day. Do not listen at high volume levels for long periods of time to prevent hearing damage.Preventing damage to the product and dysfunctions̈Always keep the product dry and do not expose it to extreme temperatures (hairdryer, heater, extended exposure to sunlight, etc.) to avoid corrosion or deformation.̈Only clean the product with a soft, dry cloth.̈Never repair or attempt to repair a defective product yourself.

With NoiseGard™ switched off, the headset can be used as a conventional headset.̈Set the NoiseGard™ ON/OFF switch 3 to the desired position:ON NoiseGard™ is switched on.The LED 2 lights up, indicating the battery chargestatus (see page 13) or power supply via theaircraft DC power supply system.OFF NoiseGard™ is switched off.The LED 2 is off.Using the headsetAdjusting the volumeThe two slide volume controls 1 allow you to adjust the volume for the left and right channel separately.Switching between mono and stereo modeThe mono/stereo switch 4 allows you to switch between mono (k ) and stereo (k k ) mode, depending on the audio system.Changing the left and right stereo channelThe position “R ” or “L ” of the BOOM switch 5 corresponds to the position of the microphone on the left or right side of the mouth. When the microphone boom is rotated to permit left or right side microphone orientation, the BOOM switch allows you to correctly assign the audio channels (L/R) to the appropriate headphone sides. This enables the correct orientation of the volume controls and any stereo audio signals. To move the BOOMswitch, use a pointed tool.This headset is capable of producing high sound pressure levels. Higher volumes or longer durations can damage your hearing!̈Set the volume to a medium level. Make sure that you can hear critical sounds such as warning alarms.Using the headsetPowering NoiseGard™ via two (rechargeable) batteries ̈Insert two 1.5 V AA alkaline batteries (IEC LR 6) or two 1.2 V AA rechargeable batteries (IEC LR 6). Observe correct polarity when inserting the batteries.The operating time with batteries/rechargeable batteries is approx. 60 hours. With NoiseGard™ switched on (see page 11), the LED 2 provides information on the remaining battery/rechargeable battery capacity:Activating the “auto shut-off” functionThe battery-saving “auto shut-off” function automatically switches the NoiseGard™ electronics off when the headset is disconnected from the audio system or when the aircraft avionics are switched off. The headset is delivered ex-works with the function deactivated. You can activate “auto shut-off” as follows:LED 2Meaning lights up yellow The battery capacity is sufficient.lights up redThe batteries are flat. Replace the batteries.Using the headseẗacoustic signals in the immediate vicinity. Unwanted background noise is filtered out, only allowing the voice of the other person to pass through the headset.̈Press the button A to switch the TalkThrough function on. The LED < lights up. Press the button again to switch TalkThrough off.Connecting a mobile telephoneThe 2.5 mm jack socket 8 allows you to connect a mobile telephone. For this purpose, the NoiseGard™ active noise compensation must be switched on and the microphone connector must be connected to the aircraft radio/audio. A suitable adapter for your mobile telephone with 2.5 mm jack socket is available from your specialist retailer.TalkThrough can only be used when the NoiseGard™active noise compensation is switched on .Making telephone calls or operating the mobile telephone limits your attention and may cause accidents.̈During flight operation, do not use the headset for telephone calls!Using the headseẗConnect the audio cable to the 2.5 mm jack socket 8 on the control unit I and to the corresponding jack socket on your mobile telephone.You can adjust the volume of the mobile telephone via the headset’s control unit. However, the functions of the mobile telephone cannot be controlled via the headset’s control unit.̈Operate your mobile telephone as usual and observe the instructions of the manufacturer.The latest list of compatible mobile telephones is available on our website at .Connecting an additional audio playerThe 3.5 mm jack socket 6 allows you to connect and listen to an audio player (not supplied) through the headset. For this purpose, the NoiseGard™ active noise compensation must be switched on.Listening to music or operating an audio devicelimits your attention and may cause accidents.̈During flight operation, do not use the headset for listening to additional audio sources!Using the headseẗConnect the audio cable to the 3.5 mm jack socket 6 on the control unit I and to the corresponding jack socket on your audio player.Attaching the belt clipThe belt clip allows you to attach the control unit to the seat belt so that the control unit doesn’t hinder you.̈Make sure not to squeeze any connection cable.This headset is capable of producing high sound pressure levels. Higher volumes or longer durations can damage your hearing!̈Set the volume to a medium level. Make sure that you can hear critical sounds such as warningalarms.Using the headsetAttaching the cable clipThe cable clip allows you to attach the headphone cable to your clothing so that the cable doesn’t hinder or distract you.̈Loop the cable through the clip so that the headphone cable doesn‘t hinder you.Care and maintenanceCare and maintenanceCleaning and maintaining the headseẗBefore cleaning, pull out the plugs of the product from the connections in the aircraft.̈Only use a soft, dry cloth to clean the product.Replacing the ear padsFor reasons of hygiene, you should replace the ear pads annually.̈Grasp the edge of the ear pad and pull sharply.̈Attach the new ear pad to the ear cup by pressing firmly around the ear pad until you hear all 12 latches lock into place.CAUTIONLiquids can damage the product!Liquids entering the product can short-circuit the electronics or damage the mechanics. Solvents or cleansing agents can damage the surface of the product.̈Keep all liquids far away from the product.For reasons of hygiene, you should replace the headband paddings annually.̈Pull the Ziploc type fastening strips of the old headband paddings apart. If necessary, use a pointed tool.̈Put the new headband paddings around the headbands.̈Attach the new headband paddings by joining the fastenings strips.Accessories and spare partsAccessories and spare partsBy changing the cables, you can simply retrofit different control units (see page 9 and 10) or connectors (see page 23) to your headset.Accessories•Cable -CP Cat.
