Section two. Standard lamp data sheets

Lamps for cycle headlamps and rear lamps operating at up to 6 V. Methods of test and conditions of compliance to ensure quality and interchangeability.

This British Standard specifies requirements for lamps for use in cycle headlamps and rear lamps that operate at supply voltages up to 6 V. It specifies the technical requirements that ensure quality and interchangeability and it describes the methods of test to be used, together with the conditions of compliance to be applied to the results, to decide whether a batch of lamps is acceptable.

Section 1 specifies general requirements for lamps and section 2 consists of individual standard lamp data sheets giving details pertinent to each type of lamp.
