well, that's partly true.
It depends on which standard they are refering to. In US, they uses ASTM,
Japan - JIS, UK - BS, Malaysia - SIRIM, German - DIN, International - ISO.
Other considerations are - on what basis are the rims being certified,
what tests have been done, what is the threshold of the test, sampling
process and so on. The standards also varies, some focus on the
manufacturing process, some on the end product performance. but now a days
i think both factors are taken into consideration. I dunno much about the
standardization thing but I do know that it's sometime confusing. That's
why SIRIM approved products are sometime not up to end-user's expectation.
It has nothing to do with the standard (whether it's good or not), it's
about which few tests has been carried out, the threshold of the tests and
the nature of the tests.
Let say, a test reports that a rim can sustain 600kg (simply put) of load
without deformation in shape and strength. Does it means that the rim is
good? Not really. The in-lad testing method never 100% represent the real
on-road usage. A simple 1.5"-deep hole, if hitted at 40km/h - definitely
can be handled. But if it's being hitted at 100km/h, that's another story.
the impact could be much larger than 600kg.
There'll be a damn whole page if we want to talk abou the standards but..
well.. no one knows better than the organizations. So why confuse
ourselves? Haha!!
