【求助】求问一个EN71-9的计算方式

These limits have been derived from the results obtained on toy samples that were analysed by both this Static
headspace method (A.2) and the Thermal desorption method (A.3). The following values were assumed for the
mass of toy type and its reference volume: tent: 1 kg & 1 m3; inflatable toy: 500 g & 25 m3 (room volume, of which
10 % inhaled); helmet: 200 g & 0,01 m3 (internal volume). The limits should be regarded as indicative and, where
more accurate values can be substituted for the assumptions made, may be adjusted using the following formula
[which is derived from the relative loading factor (see A.3.6.2)]:
Adjusted emission limit = emission limit x assumed mass of toy x substituted reference volume
substituted mass of toy x assumed reference volume

标准有解释，不过看你的客户接不接受，因为严格来说是用热脱跗结果才能判定的。
