BS EN ISO 9239-1 uses measurements in the test method which provide a basis for estimating one aspect of fire exposure behaviour of floorings

To ensure that materials used for nosing and the methods used for jointing nosing to treads are adequate to resist vertical impact loading

BS EN 60444 9 is the ninth part of an international standard that focuses on the measurement of quartz crystal unit parameters. BS EN 60444 9 describes two methods for determining the spurious (unwanted) modes of piezoelectric crystal resonators. It specifies the following methods: Method A i. e., full parameter determination, which allows the determination
