(a) Purpose.  This part 1633 establishes flammability requirements that all mattress sets must meet before sale or introduction into commerce. The purpose of the standard is to reduce deaths and injuries associated with mattress fires by limiting the size of the fire generated by a mattress set during a thirty minute test.

(b) Scope.

(1) All mattress sets, as defined in § 1633.2(c), manufactured, imported, or renovated on or after the effective date of this standard are subject to the requirements of the standard.

(2) One-of-a-kind mattress sets may be exempted from testing under this standard in accordance with § 1633.13(c).

(c) Applicability.  The requirements of this part 1633 shall apply to each “manufacturer” (as that term is defined in § 1633.2(k)) of mattress sets which are manufactured for sale in commerce.

§ 1633.2 Definitions.

Test Requirement 测试要求：

(1)受测床垫在30 min的测试中,其峰值热释放值不得超过200 kW;
(2)测试前10 min热释放总量不得超过15MJ;
(3)制造商必须按照规定的方法测试至少三个样品,如果有一个样品未能同时满足上述两项要求,则判定为不合格。此外,该法规还对质量控制、记录保存、标签等作了要求。

两个T型burner 火源(气体为丙烷，一个火源在床垫表面，另一个在侧面) 让床垫的侧面要接受燃烧50秒，而床垫上面部分要持续燃烧70秒后才将火源移开。

Performance Requirements 评判要求

1.在测试开始后30分钟内的任何时间最大散热速率不超过200KW;
2.在测试的前10分钟的散热总量为25MJ，为了安全，当火扩大以至对设备不安全时需要扑灭，操作人员可中止测试并记录失败。(每一个样品都满足以上要求才Pass)

Limit 限量:

1)The peak rate of heat release should be less than 200kW within 30 minutes
2)The total heat release should be less than 15MJ in the first 10 minutes of the test

Sample Size 样品数量 / 送样规格: see below

1) 3 sets of completed products or prototypes
2) All tests must be conducted on specimens that are no smaller than a twin size, unless the largest size mattress set produced is smaller than a twin size, in which case the largest size must be tested. A Twin size means any mattress with the dimensions 38 inches (in) (965 millimeters) x 74.5 in. (1892 mm); all dimensions may vary by 1/2 in. (13mm)
3) Testing of mattress sets. Mattresses labeled for sale with a foundation shall be tested with such foundation. Mattresses labeled for sale without a foundation shall be tested alone.

Lead Time / TAT (Turn Around Time) 测试周期: 常规服务 Regular service 7-9 working days
