Glossar - B
Drinking water approval for Belgium
A defined quantity of some product or material produced under the same conditions. A distinction is made between material, production and shipping batches.
Material batch = all parts manufactured from a raw material shipment.
All parts manufactured from a continuous production process undertaken without change is referred to as a production batch. All components making up a shipment of goods are a shipping batch.
'Oxygen' certificate issued by the BAM (German Material Research and Testing Institute)
The licence applies only for specific operating conditions:
Temperature max. oxygen pressure
to 60°C 50 bar
> 60°C to 100°C 40 bar
> 100°C to 140°C 30 bar
One of the most widely recognised functions of the BAM is checking pyrotechnic items, e.g. fireworks. Only pyrotechnic items with certification from the BAM may be sold in Germany. Other high-profile public activities of the BAM are the certification of protective capsules for hazardous goods in shipment, the further development of non-destruction tests for the early identification of damage and the avoidance of accidents, and the development and provision of reference materials for analytical chemistry, e.g. in environmental laboratories.

XX = application key number
XXX = consecutive number
P = material abbreviation
XX = Shore A hardness
D = only necessary when Shore D is required
M = only necessary when compound release is required
Both soot and mineral bulking agents are added to rubber in great quantities to make it possible to process it and to obtain the desired vulcanisation properties, especially hardness. Most bulking agents have a more or less 'hardening' effect on the vulcanised material. What is understood as 'hardening effect' in the rubber industry is the improvement of a series of vulcanisation properties, such as resistance to abrasion, elongation at tear, tensile value, and resistance to tear propagation and abrasion. However there is hardly any bulking agent with the effect of reinforcing all of these properties at the same time. It is therefore appropriate to speak of reinforcing effects only in connection with specific mechanical properties.
