|Other elements for reference purposes only:|
Brinell hardness 90 – 100 approximately.
Unless contracted at the time of negotiation, other elements above do not give Buyer right to reject and may only form the basis for further discussion in the event material assays outside of these maxes.
Sponge, in range 12 – 70mm.
TG100: Original producer steel drums under argon, uniform net weights per lot.
TG-TV: Original producer steel drums, uniform net weights per lot.
Lot Size & Tolerance
10 MT (+/- 2%)
Standard documentation, as per MMTA Consolidated Regulations, plus detailed packing list and producers original, or photocopy of, producers quality certificate.
Weighing & Sampling
As per MMTA Consolidated Regulations.
1. TG 90 is an acceptable delivery under a TG 100 contract.
2. In the case of Chinese or Japanese material, analysis to be mutually agreed at the time of contract, with quality certificates of the appropriate sales organisation.
3. Sponge units may reduce in size during transportation and handling.

Open all containers, note any different markings or indications of heterogeneity or contamination. Opening all the containers may well be impractical, alternatively open at least the number of drums for a 10 MT parcel, increasing by a 20% of that number for each subsequent sub lot of 10 MT. That is to say [N + 20% N/2] drums for 20 MT, [N + 20% N/3] drums for 30 MT, etc.
If there are no indications of material heterogeneity then sample on an incremental basis of 10 MT sublots. If heterogeneity is suspected select the incremental groups accordingly but in sublots of 10 MT or less. Tip 10% of the opened drums and using the appropriate shov-el take samples top middle and bottom. The increments for each sublot should be mixed and an appropriate sample selected with each individual piece being drilled, taking the nec-essary precautions, and placed in an argon flushed container. All opened drums must be refilled with argon and resealed after inspection and sampling.
The drillings from each incremental sub lot should be mixed, drillings or pieces subdivided if necessary, to produce a homogeneous bulk sample in each instance.
Two options are then open:
(a) Quality samples can be drawn from each homogenised sub lot bulk sample for analysis.
(b) A composite can be prepared from portions of each of the sublots to give a total parcel bulk sample from which total parcel quality samples may be drawn.
The balance of the sub lots being held for reference purposes.
