: I cannot speak for the quality of product datasheets in the construction industry.
But for example, in consumer electronics, 150 watts is simply not the same power everywhere.
Impulse, continuous load, sinusoidal, RMS, music or even PMP power, at what distortion rate, with white or pink noise, one channel or all channels driven, 4 ohms, 6 ohms, 8 ohms.
Frequency responses: -3dB, -6dB, 1W at 1m or 0.5m?
All have been seen in official technical datasheets.
And of course binding.
Just like battery life in mobile phones or notebooks. Sound emissions in washing machines, refrigerators, and dishwashers. What were the measurement conditions? According to what usage scheme was it carried out? Datasheets usually remain silent about this.
But if nothing is said about the measurement conditions, any number can be considered binding or you have to admit that every number is actually non-binding.
I do not know now how it is for example with abrasion and hardness classes of floors, maybe there is a cross-manufacturer standard or agreement on levels and measurement conditions here. But I would doubt that these also take long-term tests or realistic conditions into account, which of course occur in everyday life. Solar radiation for example: one floor might show discoloration or lose abrasion resistance after two summers, the next remains like on the first day.
Usually, this is not the case for products used by end customers.
So insofar I trust more on evaluations on the internet and try to read between the lines than to trust the non-transparent information of a manufacturer with whom I have no experience myself.
Datasheets are a first clue to filter in a confusing product landscape. But if you then have one to three favorites, you are well advised to rely on experiences. Even better, if these are experiences from experts – but independent ones and not blindly adopting manufacturer specifications.
