BS 1970:2012 - The British Standards BS 1970 and BS 1970:2012 (updated version) define, for instance, the bottles’ filling characteristics, safety instructions, allowed materials and components as well as testing methods such as tensile tests for PVC bottles. Wikipedia

Edits and Omissions- As we present our products, we interpret and publish the content which we are supplied with. Because many of our products are part of a set of many or one in a color range of several - Descriptions are elaborated to include all the attributes in the group rather than tailored to one product. We try our best to fix as best as we can but often times we have to omit information that isn't clear to us. For example, we might state the color of the Cover but not the Bottle or the other way around. We try update as soon as we get better info. Customer comments always welcome: support@hotwaterbottle.com

PVC -  Several brands of Hot Water Bottles are made from different types of PVC - We cannot guarantee that they are all 100% PVC (Some may contain Latex Rubber and other unknowns?). Another problem lies in the way Product  Descriptions are passed on to us - Often times the the term "PVC" and "Rubber" are used interchangeably or are called "PVC Rubber". We are working with suppliers to find an accredited sources for "Allergy Free" products. Until then we recommend using top Brands like "Fashy" and for customers to do their own fact finding before purchasing from us. (Fashy- "Manufactured with the most advanced thermoplastic materials on the planet. Safe, effective, hygienic, virtually odor-free).

Phthalates - are a series of chemical substances, which are mainly used as plasticizers added to polyvinyl chloride (PVC) plastics for softening effects. Phthalates can potentially disrupt the endocrine system. (Wikipedia)

Infants and Hot Water Bottles - Hot water bottles are not intended for Babies and Toddlers under Three Years Old. This is a consensus repeated by many of the leading manufacturers.

Litres to Fluid Ounces -  2 Litres is very close to 67.63 Fluid Ounces and 1.6 Litres is very close to 54.1 Fluid Ounces. These are the most common equivalents listed and are the volumes for Large and Small collections.

Litres to Quarts - 2 Litres is very close to 2.1 Quarts

Rubber - People with Latex Allergies should avoid Rubber Products.

Small, Medium and Large - We removed the Medium size from the collections. As we ultimately have quote the manufacturers listed Size - We found too much of a crossover between (Small / Medium) and (Medium / Large) to make Medium a worthwhile distinction. We now have Small which mostly represents 1.6 Litres and lower and Large which is above this. We also didn't include an Extra Large Collection (Above 2 Litres). Products in this range are more easily Identified as Non Traditional
