◆ 澳标AS/NZS 4859.1:2018
AS/NZS 4859.1:2018 Materials for the thermal insulation of buildings - General criteria and technical provisions
AS/NZS 4859.1:2018 标准概述了建筑物隔热材料的一般标准和技术规定。
单个材料或绝缘类型的具体要求:
(1) 硬质泡沫聚氨酯(RC/PUR)-AS 1366.1;
(2) 硬质多孔聚异氰尿酸盐(RC/PIR)-AS 1366.2;
(3) 硬质泡沫聚苯乙烯模塑(RC/PS-M)-AS 1366.3;
(4) 硬质多孔挤塑聚苯乙烯(RC/PS-E)-AS 1366.4;
(5) 脲醛泡沫保温原位凝固泡沫-AS 4073。
(a) Rigid cellular polyurethane (RC/PUR) - AS 1366.1;
(b) Rigid cellular polyisocyanurate (RC/PIR) - AS 1366.2;
(c) Rigid cellular polystyrene Moulded (RC/PS-M) - AS 1366.3;
(d) Rigid cellular polystyrene Extruded (RC/PS-E) - AS 1366.4; and
(e) Urea-formaldehyde foam thermal insulationIn situ set foam - AS 4073.
The scope of this Standard does not cover requirements for fire performance
◆ AS/NZS 4859.1:2018新标准有哪些变化?
更新了导热值(R值)的计算和声明方式。修订后的标准AS/NZS 4859.1:2018的大变化与热试验和性能标签的正式声明有关:热测试:对于根据本标准评估的每种材料,需要对至少10个测试结果进行统计评估。该统计评估应根据统计调整的平均值确定测试产品的R值和导热系数,该平均值代表50%的分位数,单侧公差区间的置信度为90%。表示为R50/90或λ50/90。相同的统计评估适用于所有绝缘材料,真空绝缘板除外。
◆ How is it Changing AS/NZS 4859.1:2018?
√ A statistical assessment of at least 10 test results is required for each material assessed under the standard.
√ This statistical assessment shall determine the R-value and thermal conductivity for the products tested from the statistically adjusted mean values representing a 50% fractile with 90% confidence for a one-sided tolerance interval. To be expressed as R50/90 or λ50/90.
√ The same statistical assessment is applicable for all insulation materials, except for vacuum insulation panels.
