今天这篇文章，主要简单介绍下UL 962家具补充条款的相关内容。

SUPPLEMENT SA - CLASS 2, LPS or SELV MOTOR AND HEATING CIRCUITS IN FURNISHINGS
补充条款-class 2, LPS 或 SELV 电机和发热电路在家具中的内容

SA1 Scope
SA1.1 The requirements of this supplement address potential fire hazards associated with low voltage motors and low voltage heating circuits powered by Class 2, Limited Power Source (LPS) and Safety Extra Low Voltage (SELV) circuits used in furnishings.
SA1.1本补充要求解决与低电压相关的潜在火灾危险电机和低压加热电路供电的CLASS2 电路，有限电源(LPS)和安全家具中使用的特低电压(SELV)电路。

SA1.2 Class 2, Limited Power Source (LPS) or Safety Extra Low Voltage (SELV) circuits powering low voltage motors and low voltage heating used in furnishings shall comply with UL 962 except as modified by the requirements contained in this supplement.
SA1.2用于家具中的低压电机和低压加热的CLASS2，有限电源(LPS)或安全特低压(SELV)电路应符合UL 962，除非对本附录中的要求进行了修改。

SA2 Glossary
SA2.1 For the purposes of this supplement, the following definitions apply.
SA2.1为了本附录的目的，适用以下定义

SA2.2 MOMENTARY CONTACT SWITCH – A switch that requires constant pressure to hold it in the on position, and does not include means for locking in the on position.
SA2.2瞬时接触开关-一种需要恒压将其保持在开启位置的开关，不包括锁定在开启位置的方法。

SA2.3 SAFETY EXTRA LOW VOLTAGE (SELV) CIRCUIT – An isolated secondary circuit that under normal operating conditions and single fault conditions provides a voltage that is 30 V rms (42.4 V peak) or 60 V DC or less. The current may exceed Class 2 limitations. These circuits are derived from a source evaluated to the SELV requirements in the Standard for Information Technology Equipment – Safety – Part 1: General Requirements, UL 60950-1 for the application of these requirements.
SA2.3安全特低电压(SELV)电路-在正常工作条件和单故障条件下提供30v有效值(峰值42.4 V)或60v直流或更少的电压的隔离二级电路。电流可能超过class2限制。这些电路来自于根据信息技术设备标准-安全-第1部分:通用要求，UL 60950-1中SELV要求评估的源。
