Tests for mechanical and physical properties of aggregates - Methods for the determination of resistance to fragmentationWhat is BS EN 10972 about? BS EN 10972 is the second part of the BS EN 1097 series of documents that describes the reference method, the Los Angeles test, used for type testing and in case of dispute (and an alternative method, the impact test) for determining the resistance to fragmentation of coarse aggregates (main text) and aggregates for railway ballast. For other purposes, in particular factory production control, other methods are possible

The rules in ISO 2859‑4 have been devised such that there is only an acceptably small risk of contradicting the declared quality level when in fact the actual level conforms to the declared level

The guidance in PD 5304:2019 includes:

Tolerances on flatness

It’s also important to take into account that these requirements apply to luminaires with ignitors built in and separate from ballasts

PD CEN/TR 16625 on flexible sheets for waterproofing is useful for:
