No. IS0 5446-1980 (E) see IS0 565. 5.3.2 If the purchaser requires particle size ranges and/or tolerances other than those given in table 7, these shall be agreed upon between supplier and purchaser. 5.4 Extraneous contamination The material shall be as free as possible from extraneous con- tamination. 6 Testing 6.1 Sampling for chemical analysis and sieve analysis 6.1.1 Sampling for chemical analysis and sieve analysisa shall preferably be carried out by the method specified in IS0 3713sj, but other methods of sampling having similar precision may also be used. 6.1.2 Sampling is usually carried out at the supplier s stockyard, unless otherwise agreed. Wherever sampling is car- ried out, representatives of both supplier and purchaser may be present. 6.1.3 If required, arbitration sampling shall be carried out by an arbitrator chosen by mutual agreement between supplier and purchaser. Sampling shall be carried out by the method specified in IS0 371331, but other methods of sampling having similar precision may be agreed upon between supplier, pur- chaser and arbitrator. The sample obtained by arbitration shall be accepted by both parties. 6.2 Analysis 6.2.1 The chemical analysis of ferromanganese shall preferably be carried out by the method specified in IS0 4159, but other methods of chemical analysis having similar precision may also be used. 6.2.2 Ferromanganese shall be furnished with an analysis cer- tificate, established by the supplier, for the manganese content and, if agreed, the contents of other elements either specified in tables 1 to 6 or additionally agreed and, upon request of the purchaser, with a sample representative of the consignment. 6.2.3 In case of dispute, one of the following two procedures may be used. 6.2.3.1 Contradictory analysis The chemical analysis shall be carried out on the same sample and preferably by the method specified in IS0 4159. Other methods of chemical analysis having similar precision may be used, but shall be agreed upon between supplier and pur- chaser. If the difference between the results of the two analyses is within x %4), the mean value shall apply. If the difference ex- ceeds x %, then, provided that no other agreement is reached, arbitration analysis shall be carried out by an arbitrator chosen by mutual agreement between supplier and purchaser. 1) The point of delivery is defined as that point where the responsibility for the consignment passes from supplier to purchaser. If neither the supplier nor the purchaser is responsible for the transportation, then the point at which the values become valid shall be agreed upon. 2) Sieve analysis of ferroalloys will form the subject of IS0 4551. 3) A method of sampling specific to ferromanganese will form the subject of IS0 4553. 4) The value of x will be specified later. In the meantime, the value should be agreed upon between purchaser and supplier. 2 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/28/2007 00:05:52 MDTNo reproduction or networking permitted without license from IHS -,-,- IS0 5446-1990 (E) 6.2.3.2 Arbitration analysis disputed values or not more than y %tr outside one of these values.
