BS EN 16241 is a European standard that discusses slack adjusters used in railways to prolong the life of slack adjusters. BS EN 16241 outlines principles for designing, manufacturing, and type testing slack adjusters.
BS EN 16241 applies to double-acting slack adjusters designed to control the block (shoe) to tread (wheel) clearance of tread braked vehicles with conventional brake cylinders and rigging, without considering the track-gauge.
Note 1: These requirements cannot be written in sufficient detail to ensure good workmanship or proper construction. Each manufacturer is therefore responsible for taking every necessary step to make sure that the quality of workmanship and construction is such as to ensure accordance with good engineering practice.
Note 2: The term used for this device by UIC is “Brake rigging adjuster”.
BS EN 16241 on the slack adjusters used in railways is useful for:
A slack adjuster is a device to compensate for the wear of brake shoes, wheel treads, and brake rigging pivots to maintain a nominal block to tread clearance.
BS EN 16241 guideline assists you with requirements on maintenance of block to tread clearance, take up, payout, shock, vibration, space envelope, maximum load absorption, service life, ambient temperature, other environmental conditions, humidity, rain, snow, ice, hail, solar radiation, resistance to pollution, and external appearance for slack adjuster for railways.
BS EN 16241 guides on, materials on type test methods, sampling for a typing test, test requirements, test procedure, check of physical geometrical characteristics, check of geometrical characteristics, operation at extreme temperatures, maximum load absorption, life test, approval validity, and test report for slack adjuster for railways.
BS EN 16241 also assists in routine tests, designations, identification, and marking for slack adjusters for railways.
With compliance and obedience and of BS EN 16241 you can enhance the performance of slack adjusters used in railways. In addition, the methods provided support you to assess slack adjusters properly and will prolong the life of slack adjusters.
