1
|
A substance which is capable by chemical reaction in itself of producing gas at such a temperature, pressure and such a speed as could cause damage to surroundings or which is designed to produce an effect by heat, light, sound, gas or smoke or a combination of these as a result of non-detonative self-sustaining exothermic chemical reactions.
在某一温度、压力或速度条件下,自身会产生化学反应,对周围环境带来伤害,或经设计自身能发生非爆炸性放热化学反应,产生热、光、声、气体或烟雾或以上综合效果的物质。 |
Gas
气体
e.g Oxygen, propane, nitrogen
如氧、丙烷,氮 |

|
At 500C has a vapour pressure greater than 300 kilopascals absolute,or is completely gaseous at 20°C and at a standard pressure of 101.3 kilopascals.
温度为500C,蒸汽压绝对值超过300千帕,或在101.3千帕标准气压,且温度为20°C时完全为气态 |
Flammable
Liquid
易燃液体

具有燃点的液体
(a) above 61°C and which is carried at a temperature above its flash
point: or
(b) of 61°C or below except-
(b)温度为61°C或以下,除过下列情况-
· a liquid with a flash point equal to or more than 35°C which
does not support combustion;
· a viscous substance; or
· a flammable gas.
· 燃点大于等于35°C但不支持燃烧的液体;
· 粘性物质;或
· 易燃气体。

Flammable
Solids
易燃固体
E.g. sulphur
如硫 |
4.1
|
· A solid which is steadily combustible, or may cause/contribute towards fire through friction;
· a self-reactive or related substance which is liable to undergo a strongly exothermic reaction;
· 可燃,或通过摩擦可能导致/引发火灾的固体;
· 会发生强烈放热反应的自身反应或类似的物质;
· 对其爆炸性质进行了处理的经处理爆炸物质。 |
Spontaneously
combustible
substances
自燃物
E.g. cotton, carbon, phophorous
如棉、碳,磷 |
4.2 |
A substance which is liable to spontaneous combustion under conditions met in carriage or liable to self-heating when in contact with air, and liable to catch fire.
在运输条件下容易自燃或在与空气接触之后容易自热或容易着火的物质。 |
Substance which in contact with water emits flammable gas
与水接触会释放出易燃气体的物质
e.g lithium, sodium, potassium
如锂、钠,钾 |
4.3 |
A substance which in contact with water is liable to become spontaneously combustible or to give off a flammable gas
在与水接触后容易变成自燃物或释放出可燃气体的物质。 |
Oxidising
Substance
氧化性物质
e.g. Hydrogen peroxide, ammonium nitrate, potassium permanaganate

5.1
|
A substance other than on organic peroxide, which although not necessarily combustible, may by yielding oxygen or by a similar process cause/contribute to the combustion of other material.
除有机氧化物之外,本身不一定为可燃物,但是能释放出氧气或通过类似反应导致/引发其他物质燃烧的物质。 |
Organic
Peroxide
有机过氧化物
e.g. polyester resins/fillers
如聚酯树脂/填料 |
5.2 |
A substance which is –
具备以下条件的物质-
(a) an organic peroxide; and
(b) an unstable substance which may undergo exothermic self accelerating
decomposition.
