What Are the Brass Ring Moulds Used For?
Building-materials laboratories, lime and plaster producers and civil engineering courses use the rings to check that a lime or plaster will not pop, pit or blister after it is applied. The ring is set on its glass plate, filled with the test material and struck off level, and the pats are examined after the required exposure. The taper helps release each pat; wipe the ring and plate clean after every test.
Frequently Asked Questions
How many ring moulds does one pat test need?
Three. Order rings in multiples of three so that each sample of lime or plaster can be tested as a full set.
What size is each ring?
Each ring measures 100 mm in diameter and 5 mm deep, with an internal taper of 5° that helps the finished pat come away cleanly.
Is a glass plate included?
Yes. Every ring mould is supplied complete with a glass plate, which forms the base of the pat during casting.
Who makes the Brass Ring Mould Pat Test?
