國內(nèi)俄羅斯標準緊固件測試問題

請問各位專家，國內(nèi)是否有測試俄羅斯標準緊固件的機構(gòu)呢？可否提供下 以下（附件）為測試標準 Method of test for high work life fasteners. 1. Requirements to test equipment. 1.1. Test should be held on test plants, which provide accuracy of measurements of force not worse than 2% 1.2. Frequency of loading should be 3..5 Hz with force 0-5000 kg-force. 1.3. Tested fasteners should be mounted in holders made of construction steel with breaking point not less than 100 kg force/sq.mm. Scheme of holding device is on figure 1. Fig. 1. Scheme of holding device. 1-tested bolt, 2-nut, 3,4-washers, 5-upper holder, 6-upper puller, 7-lower holder, 8-lower puller 1.4. Washers made of construction steel with breaking point not less than 80 kg-force/sq.mm should be mounted under head of bolt and nut. See drawing 2. Fig.2. Washers. 1-for bolts with head over surface, 2-for bolts with hidden head, 3-for nuts, bolts and studs. 1.5. Inner diameter in washers should be 0.2 mm more than bolt rated diameter. 1.6. Accuracy of thickness of washers not more than 0.03 mm 1.7. During tests axes of loaded parts should be coincident. 1.8. Nuts with breaking point 90..110 kg force/sq.mm should be used for holding tested parts. Height of nuts should be not less than rated diameter of tested bolt (stud). 1.9. When studs are tested it’s recommended to mount self-stopping nut at one side to prevent unscrew while mounting. 2. Method of work life tests 2.1. Work life tests of fasteners should be held in not tight screw condition. Min load 0-50 kg force. Frequency 3..5 Hz. Sine force application. Increasing of load frequency up to 10 Hz is allowed. 2.2. 10 parts from each shipment should be tested. Load is applied until base number from table 1 is reached. 2.3. Max load should be set according with rated diameter of tested parts. Table 1. Rated diameter of bolt (stud), mm Max load, kg force work life, number of cycles 12 2750 300 000 10 1950 300 000 2.4. Bolts and studs meet technical requirements if none of first 5 bolts (studs) was destroyed during 300 000 load cycles. If one of bolts (studs) was destroyed, than next 5 bolts are tested. If one of these 5 fails, whole shipment don’t pass the test. If second 5 bolts pass the test, than whole shipment is considered high work life fasteners. 2.5. Shorter test with extended load is allowed. See table 2. Table 2. Rated diameter of bolt (stud), mm Max load, kg force work life, number of cycles 12 3350 200 000 10 2300 200 000 Bolts and studs meet technical requirements if none of first 5 bolts (studs) was destroyed during 200 000 load cycles. If one of bolts (studs) was destroyed, than next 5 bolts are tested. If one of these 5 fails, whole shipment don’t pass the test. If second 5 bolts pass the test, than whole shipment is considered high work life fasteners. 2.6. Report document should be performed after tests. Type of test plant, load range, type and material of tested part, max load during test and number of cycles should be mentioned in this document.
